Re: new speaker/amp recomendations?
+1 on replace the speakers first and then work from there. The stocks are ok at low levels but disort very quickly if pushed.
On speakers I'd suggest the Kenwood p680c's I have installed...
Installed Kenwood 6x8 p680c speakers
I'm very happy with them and while I don't listen to heavy base music a friend was playing some in my truck and it was pretty impressive.
