Just finished reinstalling my system this weekend,when my amp crapped out on me. I can't complain I've had it for almost 7 years. Soundstream Reference 405. Now I need a new amp. Must be 5/6 channel,built in crossovers, and not too expensive($300-350).Any suggestions? NOPI is coming up in 3 weeks and 3 1/2 hours is to long to listen to exhaut drone!
