I am currently buying a version 4 Type R and would like peoples advise on speakers to use and equipment to purchase to have one kicking sound in the car I currently have the Alpine TV/Sat/Video/ and 12 disc shanger with two V12 4 channel amps which was powering two 10 inch alpine subs and 4 6X9s this setup was in a 5 door Mondeo 24Valve which sounds absolutely fab but i know the 6X9s wont go in or do you know different I want a nice clear sound with plenty of seat rumbling bass ? So any ideas would be appreciated
