I have a 1976 Impala 4 door with plenty of trunk space. I am going to run four 6x9's in the back and 2 sets of tweeters. Plus four 6 1/2's in the doors. i will power these with a old school Punch 800.4. In the trunk i am seriously considering running 4-15's or 6-12's. I have 3 Memphis 1000st amps and i can get another one if i decide to run the 15's. I will probably just run the kicker cvr's b/c they are realitively enexpensive and get pretty loud with good power. If you have any other suggestions on the a sub setup it will go into consideration.
