I have a question about my power distribution.

First of all I have a Pioneer Deck - DEH-P6400
A Sony Amp - (1000W) - XM-2165GTX
A JL Audio - 12" - W3v2

My question is, my wiring is hella shotty. When I turn the stereo up past 20 (not very loud) it will either play for a little while and then cut out, it will turn back on if I turn the volume down though. Or, the amp will go into protection mode and turn itself off. Is it my wiring or is it something else?
By the way, this 1 12" pounds hard and is actually blown but still works awesome. (I have a new Sub on the way, the new Sony pentagonal)

Thanks for any help in advance
