I even flipped the bass boost switch and there is hardly any bass coming out of them. They're kicker 6x9'* too, so they're supposed to have a bit of a punch.
What I did to solve the bass problem was splice the original outputs to the rear 6x9'* (which had only bass) into a high level to RCA converter, to a mono amp. That part was actually pretty easy.
i had JBL speakers before and they had 2 connections on them, one for the speaker and one for the 3 tweeters on top
so what i meant is keep the speaker running off the same wire but connect the tweeter in the middle to the doors, and i think that should get it going
but, never tried it
