wiring aftermarket head unit in lincoln ls

[dhavol]

ok, so a few details before i start, i have a 2003 lincoln ls V8 premium, with the two 3.5" speakers the four 6x8 door speakers and the two 6x9/6x8 (i've heard different answers) on an amplifer in the back (I have a kicker L7 subwoofer in the trunk which is working fine). i recently purchased an aftermarket deck (pioneer model# 4900iB) and after reading the tech article for replacing the speaker and hooking it up the way i think its supposed to be (not 100% sure of myself) i find that my rear speakers and tweeters play well, but are alot louder then my door speakers, which can hardly be heard. now my question is

would it be the speaker impedance, or my wiring, or something completely different? if its my wiring can someone give me the exact wire connections. and I have the premium wiring harness without the rca's. any help would be welcome.

Thank you!
