Piece of shit car stereo! I should really stick to working on engines! Ok...I put a Sony amp an one 12" speaker in my car, it worked fine for a couple days...then started to work on and off...then stopped working all together. The LED on the amp was still on though...just no sound. So I figured it was the amp, and went out and bought a Fosgate amp. It worked for 5 minutes, and stopped. Same thing, the LED stays on..but no sound. Here's the kicker though...when the amp isnt working, the LED gets dim..but only in bridged mode. If I run the speaker off the left channel, the LED is fully bright and if I run the speaker off the right channel, the LED doesnt even come on! And still no noise no matter what channel its running off of. I tried running a new remote turn on, tried running new speaker wires and new RCA cables. The stereo has 2 RCA outputs, and neither helped. The speaker is 4 OHMs, the Amp is 150x1 @ 4 OHMs bridged and is 2 OHMs stable. The ground is good and secure.
