I can do this.
JBL MS8 - $400-500, refurbed would be OK with a squaretrade warranty or similar.
These amps if you have the space to give

http://www.onlinecarstereo.com/CarAudio/p_36758_Vibe_SlickBass1-V1.aspxhttp://www.onlinecarstereo.com/CarAudio/p_36762_Vibe_SlickStereo4-V1.aspxNow the ohm spec differs there as to what amp you use, so my recommendation for what subs to use will differ based on that. However, if you need powerful, relatively inexpensive, relatively shallow, and relatively low space subs,... look no further than the Sundown SD-2. The 8's, 10's, and 12's are all fantastic units for a great price. Just match the ohm spec with the desired amp, and you're good to go.
Speakers, well...the world is your oyster but ID, JBL mid-high end, and so many other good brands would all be acceptable. Since you'd be able to run active with the MS8, you can also go with separate woofers and tweeters that suit your build needs. Again, the whole option is wide open. If you budget somewhere between 200-300 for this part, you're golden.
Deadening materials. Don's site
www.sounddeadenershowdown.com and Rick's site
www.raamaudio.com would both be my recommendation for the money. Don's products like butyl rope, heavy CLD tiles, and foams are fantastic. Rick's Ensolite and lighter more all-purpose deadener works great too. Budget about $200-ish for deadening.
Wire - I use welding cable
www.wireandsupply.com is where I buy it. 1/0 gauge primary and 4 gauge secondary would be good here. Budget $50-60 for that.
Distribution blocks, fuse/circuit breakers, etc. I like ordering from Sonic Electronix for these, and I like the T-Spec units for the money and quality. So, about $30-50. Also a simple PAC TR-4 remote box for remote turn on would be smart, since our cars don't make it easy to tap into a 12V accessory line sometimes.
Speaker wire, RCA's, etc.
www.monoprice.com is the place for me. I use in-wall rated CL2 wire. 16 gauge 2 and 4 conductor is more than sufficient. $30-50 maybe.
Techflex for your wires from ebay, username furryletters. He's the man. Also has heatshrink.
Hmm... did I miss anything? Probably not other than the enclosure and "labor" itself. Though I'd vote you do it yourself.
