After having problems for a while I finally fixed my problem. All this time I thought it was a voltage problem or something with my amp or subs. They wouldn't perform for crap and it wasn't loud at all. I spent hours on the phones with the makers of my components but found out nothing. I got mad and ripped it all out of my ride. For some reason I hooked it up with it sitting in the middle of my shop and played it using my phone mp3. Guess what...it worked damn good. I went to radio shack to pick up some new rca cables. They told me it wouldn't fix my problem but as usual I ignored them. It fixed my problem completly. Always replace the cheaper pieces of the puzzle first and never listen to radio shack. You got questions, we pretend we got answers.
