I have a stock HU, Alpine mono block amp, 2 Kenwood subs and a converter thing you splice into your rear speakers for the aux for the amp. Everything is wired up like normal 12v to the battery, remote is spliced into my non-existent sun roof.
Everything worked fine for a while but now it is weird because the subs will work for like 10 seconds when I first start up my car then they will quit but the amp light will stay on. I felt the amp after this once and it is warm but not hot by any means. The subs will work fine if I leave my car with the key turned back.
Normally I can figure out sound system problems cause they are straight forward but this is really pissing me off.
Edit: I also checked the voltages on everything. I am getting a good ground and the fuse is fine.
