Question about Sony XM-2150GSX Car Audio Amplifier
I had my 12" subwoofer connceted to the 350 watt mono amplifier working fine, and I turned my amp/car off to get gas. Upon restarting my car and turning the amp back on, the subwoofer is not giving off any sort of sounds. The amplifier's power light is on. I have made sure the wiring for the subwoofer was connected and it was. I have tried everything from rewiring my amp to rewiring my radio just to make sure everything was secure. Any and all help will be very much appreciated.
You can find the color codes for a 1999 Buick Regal here. There is no dedicated amp remote wire. Neither is there a power antenna wire.
You could use the 12V "switched lead (yellow) from the radio or any switched 12V lead directly from the vehicle fuse box. I'd wire it through a dash mounted toggle switch so as to be able to turn the amp on and off manually.
The Sony 2150GSX is a 2-channel amp with the speaker terminals on either side. You do not want to ground the subwoofer itself, only the ground terminal should be connected to bare metal on the vehicle chassis or body as close to the amp as possible. The ground wire does not need to be run to the negative battery terminal.
A ground on one of the speaker leads will probably cause the amp not to power up. A ground on a speaker wire usually activates the amps protection circuit, causing it to not operate until the fault is corrected.
Hope this helps.

YOU NEED NO CHACK THE GROUND CABLE SOMETIMES WITH THE SAME POWER THAT THE AMP NEED START TO BURN THE CABLES AND IF THE GAUGE OF THE CABLE IS NOT THE CORRECT CAUSES THAT PROBLEM TRY TO PUT 2 GROUND CABLES (GREY) IN DIFERENT PLACES AND IT MUST WORK!
