I basically want to be able to power my door speakers with my amp. If the speakers are connected to the HU, and I connect the amp to the HU, so I still need to run cables from each speaker into the amp? It is a 2 channel amp. I figured once i got the dash out i could pull the speaker connections from the HU and just connect them to the amp, but then that means more wiring, because I plan to mount both of my amps in the trunk. I figured if i connected them to the amp, I might lose the fade, or the balance as well. I want to stick with my 4 door speakers, I put in kenwood 6x8's a while back, and I know they have much more potential than the stock ones. If I could, I would want midbass and, highs comming from the 6x8's, and then the bass comming from my subs.
