So I'm getting ready to redo my interior on my 1970 GTO. I've got the carpet, headliner, dash pad, and gauge bezel on the way now from Ames. Before I install all of that though I want to put in a killer sound system to give my old goat a new sound. This way I can run all of the wiring under the new carpet. I already have a radio kit by RetroSound, and a pair of Infinity 6x8 6812cf speakers for the rear. Any suggestions on amps and subs, and possibly front speakers? I'm not looking to rattle my trunk lid off with crap hip hop, but I do want a full, heavy sound with strong bass and treble presence and crystal clear sound quality. I listen to a lot of Metallica, Alice in Chains, Led Zeppelin, Black Sabbath, and other related bands. So are there any electronics gurus out there who can tell me everything I would need to achieve this?
