fuse keeps blowing

My friend has a Lanzar VIBE248. Im pretty sure he is running it at 2 x 600 Watts Max at 4 Ohms but every time he turns it up his amp fuses blow. The two fuses he has are rated at 15. He is worried about getting a higher one because he thinks it will blow his amp. What size does he need?

 

http://www.audio-warehouse.com/web/mdl/VIBE248/detail.asp that is a link to more info for his amp.

Is he blowing the fuses (they are 15 amps each correct?) in the amplifier or does he have mutiple fuse holders on the power line. I assume he is blowing the fuses in the amp. The only way that amp will make that much power (a huge, huge claim by the way) is to be struck by Lightning. A amp with two 15amp fuses is generally rated around the 60 - 100 watt rms per channel area. Lanzar claims according to their website a 2 x 300watt rms at 4 ohm rating. Either they have a unique mind blowing technology to turn rocks into gold or the wattage claim is made on the planet Uranus with 200 volts at 10000hz. This to me is a case where a manufacturer has deliberately misled the consumer, this is something I personally do not agree with. The person who sold this amplifier should also have informed you of this. If this amp is being used to power subwoofers, take it away, far away and get an amp that does not make claims but instead delivers facts. Now correct me if I'm wrong somebody, as I'm not a Lanzar dealer, but this claim is pretty large. Hopefully I had the correct info before goin off here. This does not mean that Lanzar does not build some good amplifiers by any means, it just means buyer beware.Top Secret, I can tell you but then my wife will kill me.

sounds like your ground is bad, or possibly because its a very sh!tty amp....one of the 2,,,more leaning to #2..

Yea i was thinking the same thing lanzar amps seem to cheap to be as good as they say. And his system doesnt sound very good anyways.
