A while back I installed Infinty Reference 6 1/2" 2 ways in the doors. Left the subs alone and upgraded to a Pioneer Headunit. Sounds great to me. Read the Biggest... thread.

Installing 6" 2 ways in place of the subs was a mistake in my opinion. The Infinitys in the doors and the caps and headunit sound nice in my opinion, but it is that-just an opinion. I have a roadster and it is MORE than loud enough.
