Quick question guys...all I did was turn the key to the 'on' position and the stereo won't work at all now. HU, speakers and amp are all Pioneer. Front left speaker was acting up, but why would that cause amp to go out? Power light on amp won't come on. Checked every fuse in the car, on the amp (2 on the outside, internal one maybe but I'd have to take it apart), and inline fuse. I don't really want to drive home for 4 hours in silence....any ideas? Thanks guys.

PS - Sometimes when turning car off or on, the speakers would pop/crackle. Any way to prevent this, as it never happened with stock set up?

 

Start from the beginning and move on.

Remote Wire is connected, and making contact?
Power Wire same?
Grounded properly?
Everything is wired up correctly?
Any Weird smells coming from the Amp?

Sounds to me like there is a short or possibly poor connection somewhere.

 

Everything is wired properly and it is getting power, yet it does not turn on. I've checked with a multimeter and inspected the wiring by hand. The amp doesn't smell strongly of burning or smoke or anything. It might have been shorted out, but I can't seem to find any kind of reset switch on the amp.
