I'm going for sound quality more than anything. A guy a work with has a setup very similar to this in his GTS Celica, and it sounds absolutely amazing. He pops in Dave Matthews Band or something similar, and I'm just floored at how 'real' it sounds. I'd like the entire system to get really loud with NOT a whole lot of bass. It will be going in my Z34 Lumina which has a sealed trunk with no pass-through to the cabin. If you have any other recommendations or ideas, please post them. The reasoning for going with alpine/polk stuff is because I get a fairly descent accomodation price for them since I work for an authorized retailer. Price-wise, I'm looking at approx. $1200-1300 for the actual product. The music I listen to is mostly country, or rock (Live, Trapt, Adema, and Disturbed are some of my favorites), with the OCCASIONAL rap music. MAYBE once a week or so. HEAD UNIT: Alpine CDA-7949 Pre-amp only CD player (approx $150 off of ebay) 4-CHANNEL AMP: Alpine MRV-F540 (approx $300 my cost/ebay) SUB-AMP: Alpine MRD-M500 (approx $275 my cost/ebay) FRONT SPEAKERS: Polk/MOMO MMC460 (approx $70 my cost) REAR SPEAKERS: Polk/MOMO MMC690 (approx $115 my cost) SUBWOOFERS: (2) Polk/MOMO MM124 12' subs (approx $100 each my cost) That puts me at a little under $1200, considering I DO go ahead and build my own sealed box thats recommended for those subs. Do I have better/lower priced options for the sound I am looking for? Just looking for second opinions.
