The PO (previous owner) put in a casette deck and some Pannasonc speakers that are about 6 inches, might be 8 but I have not pulled the covers and measured yet.. Speakers are shot and the Cassette has to go. Two of the speakers are mounted in the Kick pannels up front (yep through the metal) and two above the wheel wells in the back. I'm not looking to go nuts here. I just want a good full sounding stereo. My last set up was Sony head driving the mains and a pair of Bazokka's on a single Punch 45. It was in the supra and it was respectable for what it was but I'm dealing with a LOT more insides to fill with sound now. I figure I need to add a second amp to drive the mains instead of how the Head was driving both front and rear in the car and just the single Punch on the subs. The Bazookas did a decent job of mid bass fill in the little car so it sounded pretty good even though the four main speakers were only 4 inch. With the size of the inside of the Burb I just don't see getting away with that this go around. Here is what I have at the moment. Sony Explode CD 45x4 internal amp. JBL speakers that are 4 inch and I think those can be made to fit the dash. Nice and crisp so should give good definition up front. Two 8 inch Bazookas ( no interanal amp) two Punch 45 amps. Old ones with the true Mosfet power supplies. Right now most of this system is in my Supra that is for sale and I'll be pulling it in a couple days. I have a storage shelf out of the 79 that now resides in the Sub. The Bazooka's fit perfect between the shelf and the back of the back seat (no third seat). Should sound decent at that location firing towards the wall infront of the wheel wells. What speakers should I get to replace these Pannasonics? How should I wire this? Here is what I am thinking right now. The Sony has both front and rear RCA's. I figured I would run the JBL dash speakers on the head unit on front channel. The bazokas on one of the punch amps on rear RCA. That is close to how the system was set up in the other car. Should I run all four 6 inch all on one punch amp with no front to rear fade? It has a gain control as well as gains on bass and trebble on the amp so I should be able to ballance it out. between the JBL's but I'm concerned it going to be all front and I'll never hear the rears as far back as they are. Whats a decent brand for the mains that will give a good midrange and pick up where the Bazookas drop off so I can keep it all bass on the Bazookas? What ohm speakers should I get so as not to over load that amp and parralle or Series on that? I'm looking for reasonably priced. Should I just buy a third amp or can I get away with this with what I have and new speakers?
