its not CEA 2006 compliant, i dont think, so i personally wouldent buy it, alpines 2000W amp, which is certified takes 6 30A fuses, so that doing double at 4 is a longshot, and alpines amps need 0 gauge for 2000w, this one takes 4ga for double...?
but thats just what i have learned, look at fuses

^ Fuses don't lie..
4 x 30amps = 120amps
120amps x 12volts = 1440watts power consumption
Assume real world efficiency tops out at, oh lets be generous, 85%
0.85 x 1440 watts = 1224watts output, max.
Even at 14.4v and 90% efficiency it tops out at 1555watts. So to get anywhere close to a claimed 4000w it would have to be bursts at currents well into the fuses' service factor.
BUT if you realize you're going to get maybe 1200watts out of it, the price may still make it an ok deal. Reliability is something else entirely though..
