This is all going in an 87 Buick Grand National. I just want a nice sounding system all around, not trying to impress anyone or blow my own trunk lid off, just good sound as inexpensively as possible. I like the Alpine CDA-9857, looks like they can be had for about $260 shipped. Feel free to recommend another nice head unit but I am partial to Alpine. I went to a local stereo shop today and listened to the Kicker KS stuff, Alpine something, and Kenwood something, the Kickers definently sounded the best to my ears, all were around the same price. My car has 3.5's in the dash, 5.25's in the doors, and 4x10's in the back which I plan to get adapter plates to install 6x9's. I already have an A/D/S PQ20 amp, 4/3/2 ch amp, underrated old school reference amp, no frills. 80x4 at 4ohm, 100x4 at 2 ohm or 200x2 at 2 ohm. I like the Kicker CVR12, dvc 2 ohm..looks like a single 12 with a box can be had for $150. I'm thinking bridge ch 3+4 for the sub, putting 200w into the single 12" (dual 4 ohm vc's run parallel for a single 2ohm load), run the 3.5's and 5.25's in series/parallel on ch1 and the 6x9's on ch2. I've found the 3.5's for $30, the 5.25's for $50 and the 6x9's for 80. 3.5's $30 5.25's $50 6x9's $80 head unit $260 sub/box $150 $570 total, would this be an ok system and can I run all this from the one amp? I've been told that it would sound better than trying to use the internal amp on the head unit anyway.
