No.. God no.
I mean.. I cant completely knock them, they accept pretty good amounts of power, and can shake your windows...But that's really about it.
There are better products in that price range that will produce better 'sound' for your money.
But hey, like you said, you got the whole...
Rockford 3sixty.1 and 3sixty.2 (the .2 is much better)
Alpine PXA-H650
Audiocontrol... um... DQL-8?? something like that
and the JBL MS-8 (to be released eventually)
Sounds like something is effe'd in the stock wiring..
You can either take it apart and investigate, get the dealer to look at it.. or just ignore it...
