Re: Integra install problem

Assuming that your car is a negative grounded car, it should not make any difference in the power supply if the metal is galvanised, zinc conducts electric the same. As long as the ground connection is good, it should work fine.

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

    Have just purchased a cde-100 for an mx3. Does the "mounting sleeve" come with the unit? If so, is it attached to the unit as shipped? I am studying the installation instructions. Are there more explicit...

    mounting sleeve is on the radio when you buy it in most of my experiences.

    reinforcing the HEAD UNIT-(the cd player itself) with metal straps means that the DIN(the hole the radio goes into in your dash, either single or double) dash piece is probably made of a softer material, and you should mount a small metal strap, usually does not come with the unit, to the units mounting sleeve, and then mount it to the inside of the dashboard of the car with some screws or bolts. this will keep the cd player from moving around, bouncing, etc while you drive over bumps and such.

    you could probably get some metal mounting straps either from the box the radio comes in (very few come with them) or get a dash install kit from an auto parts store or a walmart for your car that will probably include all of the things you need including the dash piece, any mounting hardware, and metal straps the factory recommends or deems necessary, and even a wiring harness adapter.

    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.

    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.
    Step 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.
    Step 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.
    Step 5 Put the fuse in the fuse holder.
    Step 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.
    Step 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).
    Step 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.
    Step 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.
    Step 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.
    Step 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.
    Step 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.
    Step 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. That's all!

    Good luck.

    My subs sound distorted and dont pound right 2 12in cvr kickers and a kingwood 2 channel amp think its not wired right

    Are you sure the polarity is correct on the sub's connectors? This is very important as reversing them will cause the sub to pound inward instead of out. Make sure the wires are thick enough and that the amp's + connector goes to the red(or +) connector on the sub and that the amp is grounded properly to a clean piece of metal on the car's body. This ground wire should also be as short as possible. Also make sure the fine-tuning for the bass level on the amp is adjusted correctly and that the sub's enclosure is the correct specification ie. Ported or sealed, right size, etc.

    Ground wire

    make sure that the wire is grounded to your frame, or any other unpainted metal surface. if no unpainted surface is available, get some sandpaper, and 2 gold, copper, or silver washers (in order from best connection to worst) from your local hardware store. find a bolt near the amp, that wont make something fall apart. take the bolt out, and sand the paint off underneath it. make sure to get all the paint and primer off. put the 2 washers on the bolt, and put the ground wire between the washers. then tighten the bolt nice and tight. this will give you the best possible ground connection, without running the ground to the neg of the battery. if this still doesnt work, try running the ground to the neg of the battery. if that doesnt work, then you should have your amp looked at. hope this helps

    The car sub I have still beats with no music and makes sounds

    Probably that ground, seat bolts are bad 'cause they rust, seat belts are even worse 'cause they have some sort of coating on them to keep them tight but it screws up their grounding characteristics.
    Find a good solid metal place to ground to as well.
    Also, make sure the head unit is grounded well and if all else fails, try a new patch cord from the head unit to the amp. Process of elimination is needed to solve these problems.

    Popping noise in new stereo install

    Does this only happen when you turn the stereo on? If so, it's perfectly normal. It happens when the amplifier in your stereo powers up. It's an older car with "unshielded" wiring that isn't going to be grounded properly. Oh, and to answer your question, yes, the plus (+) and minus (-) are for positive (+) and negative (-) terminals. Make sure that red is on positive and black is on negative. Reversing the polarity (installing the wires backwards) normally won't make the system stop working but it can damage your new speakers.

    You also should make sure that you've connected the stereo ground. It will probably be screwed onto the back of the stereo and if there isn't a provided green wire in the bundle coming from the car than you'll just need to find a place to attach it to the car's metal chassis.

    My subwoofers have a heart beat to them

    Ok.... FIRST COMMON PROBLEM: recheck your ground connection. Make sure that your amps ground wire is securely bolted to the metal body of your car. Not only that- yo uhave to scrape or use sandpapar to make sure that the terminal is touching bare metal.. this is a very common problem. Nobody realizes that the ground connection is just as impoarant as the power connection... Next unplug youir rca cables from the amp. If the heartbeating goes away then mabye you have a rca cable or deck issue. If you can wiggle the rcas at the amp and make it heartbeat more or less.. then perhaps the rca terminals have come unsoldered form the circuit board... in any case without me looking at it personally this is about all i can tell you. CHeck your connections and GOOD LUCK!!!!!
