New Car, New system

So I finally recieved my court check and I was able to purchase the car of my dreams, a 99 Camaro SS. I had been saving up for a new system for awhile now and have around $700. I've already went ahead and purchased a mechman HO alternator, an optima yellow top and upgraded the grounds and power wires. With the left over money I have around $3000 to spend on a new system. And I would probaly wait and save up another grand or so if need be. So far I've picked out an Eclipse CD8445 for the HU, I personally favor the dual knobs over the newer single large knob on the newer models. But beyond that I haven't made up my mine.

I would like to get a pair of componement 6.5s for the front replacements. I've been looking at Boston Pro60's and the MB quart PCE 216s. Right now I'm running a pair of RF power 6x9s, they get the job done but thats about it. I've heard good remarks about both products and just trying to get some more opinions. After choosing the right speakers I`ll find a high quality amp to power them. Most likely an eclipse or a smaller us amp.

Allright on to the subwoofer. I haven't made up my mind whether to choose 2 12"s or 1 15". I've heard everything from 15"s being too slow and sloppy, to them being deep bass monsters.I`m looking for a subwoofer that can hit low notes while still being everyday listenable. The sub or subs will end up in a ported enclousure after I remove the rear seats to accomadate a large box. So far I've been looking at the Eclipse titaniums, Memphis Mojos, RE XXX, DD 9900, and the Soundsplinter supreme subwoofers. Any other recommendations, or which of these would I be best suited to get?

Also amp wise I would like to either run an amp per sub. And I was thinking of either going with memphis mojo amp or perhaps a exterminator us amp? Any suggestions and recommanded are highly wanted to help me choose this system. Thanks
