Why does my new setup sound like ***?
So I installed a RF 500X to a set of Polk Audio MM6501 for my fronts and a pair of Polk Audio db650 for my rears..
Before hooking them up to my amp and running them directly off my deck they sounded OK (I'm 99% sure and will verify soon).. Ever since hooking up to my AMP and running off my CarPC they sound like total ***.. The rears sound like they are blown even at low volume but I know they aren't..
Few things to note:
* The front left woofer (6 3/4") isn't hooked up yet. Can't find the wires.
* The door speakers don't fully cover the opening. The fronts came with brackets but they still don't fully cover the hole.. The rears I had to fab my own and they don't cover fully either.
* I eliminated the CarPC and ran audio from my iPhone to the AMP and still had same quality issues..
Things to check?
