Well, my whole system is ready to go as all part are now in. I was just about to start with wiring audio first and decided to test a new amp that I just got off ebay (MTX 404). I powered everyting (power to battery directly for testing, remote to ACC and stock speakers through harness). Front speakers sound just fine, but rear ones a just kind of a quite buzzing noise, I can hear that it's the audio, but it's just quite and buzzing. I thought maybe it's my wiring to the harness, but when I connect the rear speakers to front output, it's fine. So I'm concluding that it's the rear outputs of the amp.
Is that right? Is it possible to have 2 out of 4 channels be fried? If that's the case, that would really suck as I was excited to finish everything on the weekend.
Thanks
