i just got done putting a system in my 2001 4 door blazer and it sound amazing. all i have is one 12" its an alpine type e with a 350 watt amp, but it kicks really good. if your looking for a good deal, amazon.com is the way to go.

 

Thanks for all the replys guys! I ended up going with a crunch p.1 600 watt amp (similar to what someone posted) and a alpine swe 1243 sub!
