Check out the Blaupunkt PA2150 - 400W RMS and it is digital so relatively cool. They've been recommended here before. For some reason Blau has discontinued the whole line after like 5 years with no obvious replacements. I've been picking what I need for my entire system from ebay liquidaters. The PA2150 can be had for about $100 off of ebay (I think MSRP was around $300) and there are 4 or 5 up for auction right now. I got my PA2150 from "Judy's Deals" who still have a bunch listed.

As for the sub driver - go with Tone's mount and pick up a good bare 10" driver from a place like www.partsexpress.com - you'll get way more for your dollar that way.
