I found my way to these boards out of desperation, but I'm hoping to stay since it seems rather neat.
In any case, I installed my new sound system into my truck a little over a week ago, and it was running great until two days ago. I just turned the truck on, and I noticed if I turned up the volume that the speakers would cut off and the amp goes into a protect mode. I've tried turning down the gain, volume displacement, and bass boost, but it still does it. I can turn the volume up to a higher number than before though, but my stock speakers in the back over power them. Any ideas? I also tried to give a better ground too.

2 x JBL GTO938 ( 100W at 2 Ohms)
2 x Kicker 6.5" CompVT Car (125W at 2 Ohms, also these are NOT hooked up at the moment, because I'm having a hard time find room to make it look stock still)
