you could think old school. Get a 4 channel VII or VIII Hifonics, or older Fosgate. I just sold my Juno Viii on ebay. That was the best sounding 4 channel i ever had, and ive had everything. Picked up a NICE DSM Fosgate 160x4 for $105 yesterday. You could get something real nice for $250...
Yeah, the HU/processor is the most important thing along with sound deadening. The Original post asks what's the best sq amp for $250 or under so I was responding to that.
Contact 310w6, he has a ton of em. I just bought 3 of em for my next setup //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
