How hook amp up to a oem integration SNI-15 line output convertor


The amp needs an RCA input to communicate with the head unit. SOLDER the wires that come out of the head unit for the front speakers to the SNI-15, making sure that the polarity and right/left is correct. Do this for the front and rear speakers if you have a 4 channel amp. Cut the wires if you add new speakers and run the new wire from the speakers or sub box directly to the amp, or skin back the wire insulation and tap on if you use the factory speakers :( then plug your RCA cable from the SNI-15 to the input side of the amp. Don't forget that most new cars have their own amp so you might have to locate it and bypass the speakers wires around it. Don't make a mess in case you have to put everything back to factory for resale. You can avoid all this by installing a new/modern head unit with built in RCA outputs for front, rear, and sub woofer. I hope this helps. Ray

Amp stopped playing riding down the road, power light turned off. came back on when i unplugged the rca's and cuts back off when i try to plug them back in.


Faulty RCA cables, Or worse possible solution is if your amp stopped playing when it was pumping at high volume, you may have blown the RCA connectors inside your head unit Or inside your amp. If possible try another known good working amp with the wires you already have, If same happens, try different RCA cables. If problem persists after trying these, Its your head unit RCA connecters or amp RCA connectors. To rule out your amp connectors, try your amp in a friends car if possible, to rule out your head unit, try another good known working amp in your car with the wiring you already have

How do you connect the amp with the stereo


  • Choose where to put your new amp. If you are installing subwoofers it's usually best to put the amplifier in the trunk next to or attached to your subwoofer enclosure. If you are going to power your main car speakers with the amplifier then it may be better to put the amp under the passenger's seat.

  • 2

    Purchase the following wiring for the amp: A thick power cable (the thickness required depends on the total wattage of your amp, ask a sales rep or consult your amplifier's manual for the proper gauge) that will have to reach from your battery to the amp (the power cable should also have an inline fuse to protect the amplifier); 3 feet of ground cable of equal thickness as the power cable; an RCA signal cable to carry the left and right signals from your head unit to the amp; a "remote on" wire which can be any thin wire (20 to 24 gauge) that will also run from the head unit to the amp; speaker wire (if you are powering subwoofers you should only need about 3 feet of 12-gauge wire per sub, if you're going to power your main speakers you will need enough 16-gauge wire to reach each speaker from the amp, 12 feet per speaker is usually safe).

  • 3

    Gather the following tools: Screwdrivers, wire cutters, wire strippers, pliers, a utility knife, sandpaper, masking tape with a pen for labeling, 2 crimp-on o-ring ends for the power and ground cables. If you're hooking the amp to your speakers, you'll also need 2 crimp-on female spade connectors for each speaker.

  • 4

    Find a manual with instructions on taking off the dash of your car (not the whole dash--just the head unit, in order to hook wires to the back), and also to get at your car's speakers if you are hooking the amp to them.
    The Installation

  • 1

    Disconnect the ground (negative) cable from your battery. Never work on the electrical system of your car with this connected.

  • 2

    Attach the side with the fuse of the thick positive (+/red) power cable to the connector on the positive terminal of your battery; the o-ring can be sandwiched in the bolt on the connector that connects your car to the battery. Now put the fuse in the fuse holder.

  • 3

    Run the power cable through the firewall of your car (there is usually an opening on the driver's side) and to your amplifier. If your amp is in the back it is usually best to run this wire under the plastic molding that goes along the bottom edge of your car. Be careful where you run the wire because the power cables should never be near the signal or speaker wires.

  • 4

    Find a metal bolt or screw on the metal of your car near the amp to connect the ground cable to. This should be as close to the amp as possible, never more than 3 feet. Unscrew it and clean the metal surface with sandpaper. Attach the ground to it with the o-ring and screw it back down firmly.

  • 5

    Remove your head unit and run the signal and remote on wires from behind the head unit to your amp. Connect the RCA connectors and the remote on wire to the back of your head unit.

  • 6

    (If you are installing subwoofers and not running your normal speakers off the amplifier skip to step 7.) Run the 16-gauge wire from each one of your speakers to the amplifier. On the amp side use the masking tape to label each wire so you know which speaker it is. On the speaker end-strip a 1/4 inch off the ends of the wires and crimp on the female spade connectors with your pliers. Connect the spade connectors to your speakers making sure to match the positive (+/red or white) with the positive terminal and the negative (-/black) with the negative one.

  • 7

    Connect everything to your amplifier. Only strip off as much as you need off the end of each wire to make a solid connection, you don't want any exposed wire hanging out. If you have subs, attach them to the amp with the 12-gauge speaker wire.

  • 8

    Secure your amp to something. If it is in the back you can screw it directly to your subwoofer enclosure. If it is under a seat you may just want to get some straps that hold it down.

  • 9

    Reconnect your car's negative cable to the battery. Test your system and make sure everything works, going around to see that every speaker is on before you put everything back together

    How do I wire the system


    You would require an amplifier wiring kit which will contain all the wires to get power and signal to your amplifier; six feet of 14-gauge speaker wire for the subwoofers. Your speakers should have come with their own speaker wires.

    The amp connects to your head unit via an RCA cable and often a "remote on" wire, and also connects directly to your car battery through a fused "hot" wire and to the car's chassis with a short ground wire.


    The complete installation process is as follows

    #1

    Disconnect the ground (negative) cable from your battery first and foremost. NEVER work on the electrical system of your car with this connected.

    #2

    Install your new speakers. Start by removing the paneling of the speaker enclosure. Unscrew and disconnect the old speaker.

    Ideally the speaker wire will be connected to the old speakers with a metal clip that can then slide right on to your new ones. If not, cut the wire off the old speakers, strip about half an inch of it, then cut the last 6 inches or so off the speaker wire that came with your speakers so you have the proper connectors with a little wire attached, strip a half inch of those wires and twist connect them to the existing speaker wire. Bend the twists so they are in-line with the wire and wrap each connection in electrical tape so no wire is showing to protect them.

    Attach the connectors to your new speaker. Make sure to connect the negative wire (-/black) to the negative terminal on the speaker and the positive wire (+/red or white) to the positive one. Screw the speaker in place. If you have component speakers, and therefore a crossover, make sure the crossover is secured in the speaker compartment so that it does not bounce around while you drive.

    Wait to put the speaker enclosures back together until you have installed the head unit.

    #3

    Follow the instructions you got for removing whatever part of the dash covers it and take out your existing head unit. Connect the car stereo wire harness to the connector that was attached to your old radio and attach the other end to your new one. Connect the antenna cable (the single wire with the big plug at the end) to your new head unit as well.

    If the speaker wires are separate from the harness connect them using the method of stripping, twisting, and taping described above. Do this one at a time or use masking tape to label the wire to avoid confusion. If you are having trouble figuring out which wires go to which speaker or which is positive and negative read the tip at the bottom of this section.

    Do not put your new head unit into the dash yet-you still need to connect the amplifier to it. Put the speaker enclosures back together now.

    #4

    Attach the thick positive (+/red) power cable for your amplifier to the connector on positive terminal of your battery. The kit you purchased should have come with an o-ring on one end of the wire (you may have to crimp it on yourself, if so do it on the end with the fuse), this ring can be sandwiched in the bolt on the connector that connects your car to the battery.

    #5

    Put the fuse in the fuse holder.

    #6

    Run the power cable through the firewall of your car (there is usually an opening on the drivers side) and along to the back of the car where your amp is. It is usually best to run this wire under the plastic molding that goes along the bottom edge of your car, you never want the power cable to come near any speaker wires. At the same time run the remote on wire (a really thin wire from the amplifier wiring kit), through the dash where the head unit will sit, along with the power cable to the amp.

    #7

    On the other side of the car run the RCA signal cable through the dash from the head unit to the amp (it's a pair of wires together with connectors on each end).

    #8

    In the back of the car pick exactly where your amp and subwoofers are going to go. Part of choosing this is that the thick black ground cable (negative) needs to have a place to connect to the metal frame of your car. This should be as short as possible, you never want the ground cable to be longer than 3 feet.

    #9

    Find a good screw or bolt, take if off and sandpaper the metal surface that the o-ring will make contact with, then screw it down tightly.

    #10

    Attach the RCA signal cable and the remote on cable to your head unit and attach the power, ground, RCA signal, and remote on wires to your amp.

    #11

    If you have not already done so, place your subwoofer box in the trunk and attach your amplifier to it if that is what you are doing. If you are not going to screw your amp to the subwoofer box then it must be secured to something else.

    #12

    Attach the 14-gauge speaker wires to the left and right channels of the amplifier and to the speaker connectors of the subwoofer box.

    #13

    Mount your head unit into the dash. Double check all of the connections on the back of it to make sure they are secure. Then slide your head unit into its slot in the dash and screw it securely in place. Before you re-attach the dash, reconnect the ground (negative) cable to your car battery and turn the stereo on and move around the car listening to each speaker to make sure everything is working properly. Then put the dash back on. You are all done!


    Hope this helps

    Need wiring diagram


    Step 1 Understand the basics of all car stereo systems. A car stereo system consists of 4 main components and the wiring that connects them. These are the head unit, the main speakers, optional amplifiers and the subwoofers, which are also optional but generally considered a necessary part of any good system.
    Step 2 Know that the core of any car stereo is the head unit, which is the cassette or CD player that goes in the dash. All the other components are connected to the head unit by at least one pair of wires.
    Step 3 Know about car speakers. The main speakers are usually 2 in the front and 2 in the back, although with what are known as component speakers, each speaker is broken down into two speakers: one for the highs and one for the bass. Each speaker or speaker set (known as a channel) connects to the head unit via a pair of wires. Generally if you are installing a new head unit you want to install new speakers.
    Step 4 Know about amplifiers. Amplifiers provide extra power to your speakers and/or extra channels of power for additional speakers. The most common use for an amplifier (amp) is to power subwoofers. The amp connects to your head unit via an RCA cable and often a "remote on" wire, and also connects directly to your car battery through a fused "hot" wire and to the car's chassis with a short ground wire. This article assumes the use of a single amplifier connected to a pair of subwoofers. If you do not have these components simply ignore the steps specific to the amp, doing so will not affect the rest of your installation.
    Step 5 Know about subwoofers. Subwoofers are part of any good stereo system. They provide the deep bass that small speakers cannot achieve. Subwoofers are connected to the amplifier which can usually be mounted right to the subwoofer box. If you do not have subwoofers you can simply ignore the steps specific to them.
    Preparing for the installation
    Step 1 Be properly prepared. This is extremely important since you do not want to realize you're missing something in the middle of the installation.
    Step 2 Purchase the following: A car stereo wire harness which connects the existing wiring for your old head unit to your new one (this will be specific to BOTH the model and year of your car AND to the make of your new head unit); an amplifier wiring kit which will contain all the wires to get power and signal to your amplifier; six feet of 14-gauge speaker wire for the subwoofers. Your speakers should have come with their own speaker wires.
    Step 3 Obtain a guide to removing the dash, doors panels (or whatever compartment the speakers are in), and floor molding of your car. You may be able to find a guide for this online. If not, you can get a repair manual for your car at most automotive stores and online).
    Step 4 Gather the following tools: Screwdrivers to fit the job, pliers, wire cutters, wire strippers, a utility knife, sand paper or a file, electrical tape, a 9-volt battery, and any other tools that the instructions for installing the head unit and your car guides specify.
    Installation Process
    Step 1 Disconnect the ground (negative) cable from your battery first and foremost. NEVER work on the electrical system of your car with this connected.
    Step 2 Install your new speakers. Start by removing the paneling of the speaker enclosure. Unscrew and disconnect the old speaker.

    My car amp works produces distorded noise . As I plug in the rca cables i noticed that if just the tip of the connector touches i get a good sound but if i insert the whole connector it becomes distorded...


    You have a grounding issue.

    The RCA inputs of the amp are many times NOT tied to chassis ( the chassis of the car ) ground.

    Same goes for the RCA outputs of your head unit.

    The speaker outputs of your amp SHOULD NOT EVER be tied to chassis ground.

    • make sure that no speaker wire from the amplifier is touching or attached to ground.
    • Make sure that your amplifier ground (GND )( of the 3 power inputs.....GND, +12V, Rem) is securely mounted to a bare metal spot on the frame. Best practice is to have the amp GND, and the head unit GND at the exact same physical point.
    • Make sure that your RCA cable shield ( not the center tip, but the part around it ) is not touching the chassis.
    • Make sure that you have not nicked the wire while installing it and are accidentally getting a connection to the frame of the car.
    • Make sure that the head unit is grounded properly.
    • IF for some reason you have an equalizer between the head unit and the amplifier, make sure it has its own switching power supply INSIDE the EQ.
    Bad grounds are a pain to troubleshoot......best of luck....Rob

    How do i install a subwoofer and amplifier to an exhisting car audio system


    Hi,

    The basic would be to wire the sub amp to your batteries with the trigger/remote wire powered by your car stereo/head unit. When your head unit is turned on it will in turn power up the sub amp. Of course the sub woofer need to be wired to the amp. For the signal/audio wiring, normally, the head unit has a stereo RCA female connectors at the rear intended to be connected to external amps through a pair of shielded/audio cable terminated both ends with RCA males. Some units have a special RCA specifically for subs. Most eternal amps also uses RCA for their inputs.

    If the existing car audio system has already an external amp and your plan is to add on to this, the audio/signal from the head unit could be split to provide both for the existing and the new sub amp.

    If the existing car audio does not have an external amp and their are no RCA connectors at the rear of the head unit, it is still possible to connect an external/add on amp by using an adapter that connects to the speaker wires of the head unit and converting it out to line level (through RCAs) appropriate for the input of the amp.

    Hope this be of help/idea. Pls post back how things turned up or should you need additional information. it would also be nice if you can post brand/model of your head unit and intended sub amp.

    Good luck and kind regards.

    Protection light turn on with sound


    It's likely that the amp is defective but you should check the shield ground of the RCA signal cables before sending the amp off for repair.

     

    Disconnect the RCA cables from the amp.

     

    With your multimeter set to ohms, measure the resistance from the outer shield of the RCA cable to chassis ground. If it's more than a few ohms, that could be causing your problem.

     

    If this is higher than a few ohms, short the meter's leads together to make sure the meter will go down to 0 ohms.

     

    To check the shield ground of the head unit (assuming that the head unit is driving the amp directly), disconnect the RCA cables from the head unit and measure the resistance from the RCA output shield to the case of the head unit. It should essentially read 0 ohms.
