THis is what I heard from hifonics. I personal own one, its a 2003 model when they were made in Japan I think? It had been goin strong for 18 months now and Im loving it. Powered two CVR's real nice, and is now powering two Diamond CM3's real nice.
The thing I heard was that hifoncs started producing there amps in a difrerent country and the quality went down, the new hifonics is so so for the money. If you want a budget the Lanzar Opti serris is unbeatable. Freind has one on 3 CVR's and it makes your brain itch becase its so loud
