See if a) the head unit has a separate subwoofer output control, and make sure it's activated; b) the amplifier you're using for the subs has the gain control properly turned up; c) if neither of these fixes the problem, make sure all of your amp fuses are intact; d) make sure the subwoofers are in a properly-sized enclosure (too much or too little airspace can affect the sound output).

I have a pioneer GM-X524 amp connected to a TS-W253C subwoofer and it isn't working. It has 12v power to it and a solid ground, but the power light wont come on and the sub isnt working


there should be 3 power related cables connected to the amplifier:

1-From battery to amp via fuse (positive)
2-From chassis of car to amplifier (negative)
3-From head units (power continuous) (blue or blue/white cable) to the amplifiers remote connection.
this connection enables the amplifier to switch on when the head unit is switched on and off when the headunit is switched off.
I hope this helps and let me know if I can further assist you.

Signs of a blowed 15 inch subwoofer


Melted voice coil? Short circuited voice coil due to overload? does your amplifier work properly? Is the (-) properly grounded? If the SUB is in working condition and there is nothing wrong with the amplifier.
1) The amp is not powerful enough to run the sub
2) The amp is not properly grounded or powered
3) Remote Sensor wire is not connected
4) RCA Cables or Hi - input sensors are not connected
Check out the installation to verify or the sub may be damaged

How can i set up the amp alpine model mrd-m1000


The basic steps to set up a car amplifier are these: 1. Disconnect the car battery's negative terminal before doing ANY electrical work on your vehicle. Failing to do so can damage your equipment or cause injury to your person. 2. Determine where you are going to mount your amplifier. This can be in the trunk, on the back of a seat, under a seat, etc. Pick a place with good airflow, otherwise your amp may overheat while playing. 3. Run the ground wire from the mount location to a ground location. The ground location should be a location where you can securely connect the cable to the vehicle chassis, and the connection should be metal-to-metal, without any paint in between. 4. Run the speaker cables to the amp. This means any cables coming directly from subwoofers as well as RCA cables coming from the head unit. Don't forget the remote wire from the head unit. 5. Run the positive (live) power wire directly from the vehicle battery to the amp. You will most likely have to drill through the vehicle firewall in order to get the cable through. 6. Connect the ground wire to the ground location. 7. Connect the speaker wires and remote wire to the amp. Make sure these cables are connected on each end to the proper inputs. 8. Connect the ground wire to the amp. 9. Insert the fuse into the in-line fuse on the live power cable, within 2 feet (24 inches) of the positive terminal connection.If your cable didn't come with an in-line fuse, you will have to buy a fuse separately, strip the power cable, cut it, and insert the fuse in the specified location. 10. Connect the power wire to the amp first, and then to the battery. 11. Power up your system, and play some music!

Unable to receive optimum output. The bass is totally flat !


Hi, ok the Bose Acoustimass III system consists of two small cube speakers and one subwoofer unit called the Acoustimass bass module. If the subwoofer stops working, three points can be the cause of the failure. The Bose Acoustimass III is a passive system, meaning the speakers do not power themselves, but instead are connected to a receiver or amplifier. Thus, the amplifier, the speaker between the amplifier and the subwoofer, or the subwoofer itself could be the issue.

Things You'll Need:

* Amplifier
* Speaker cable
* Extra subwoofer


Instructions


Disconnect the speaker cable from the back of the Bose Accoustimass bass module and connect it to a subwoofer that is known to be working. If the subwoofer works, the bass module needs to be replaced.


Disconnect the speaker cable from the back of the receiver or amplifier you are using and from the back of the subwoofer in Step 1.


Connect a speaker cable that is known to be working between the back of the receiver or amplifier and the back of the Accoustimass module. If the module starts working, then the cable was the issue.


Disconnect the speaker cable from Step 3 from the back of the amplifier or receiver, then connect the cable to the subwoofer port on the back of an amplifier or receiver that is known to be working. If the subwoofer works, the receiver was the issue. If the subwoofer still does not work, verify that the speaker cable is in the subwoofer port of the receiver/amplifier and that the cable is connected securely to the subwoofer.



If you think you did the connection properly,Fine... If not you can use the manual from the below link and know how to connect it properly..

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

    I have a dual xpe2700 amp and it wont power on and i have everyting hooked up


    Firstly, there are some things you have to check.
    Make sure that the battery or source of power has the required power to turn it on.
    Also, make sure that the power cable is properly connected and is not broken or damaged.
    If all of the above are checked and are in good order but it still won't power on, then it is Amp that is damaged.
    In this case, you must send it to a technician to help you work on it and rectify any errors or issues.
    Hope this was helpful?
