ok, so i came across some Rockford Fosgate 6 1/2" speakers, i installed them using the O.E mounts(speakers were too small to use themselves) yes, the OE speakers come apart if you melt the plastic welds, but anyway, what color wire is positive and negative?? because i have the white wire on the pos. side, and now those Rockfords are loud, but but have no midrange hardly at all. its a dual cone speaker, with the tweeter in the middle. the OE speakers would vibrate the doors, but now those others dont even come close. do i have the wires backwards, or is the OE JBL's better?? pleases advise???
