wow good luck wiring all that. if your on a budget i would say infinity for SQ and pioneer for a little more spl. In my experiences pioneers are a little louder than infinity but infinity are a great value for their price and they sound nice.
hey I don't know what shipping and fees would but I have a group buy for 6.5 Tang band 6.5 subwoofers(30-500hz) that if done in a 3way setup would give some crazy crazy midbass to bass for you. 32$ per driver.
