amp went poof. suggestions?

[Andocommando 10+ year member]

I just bought a Visonik 900XD from a member on the forum and the transaction went well. I had everything hooked up and playing for 2 days. i have all 0 gauge wire with big3 but i run a stock alternator and battery. the amp was seeing a 2 ohm load and i had the gain set to 30Volts on my DMM, which was close to half way. well i went out of town for a few days and offered my brother to borrow my truck. he was leaving work that day, and was showing out for his friends while leaving work, and he said it quit working. so come to find out he had just started the truck, had the a/c on full blast, and had it turned up considerably loud. i came home to look at it. it blew all 4 fuses on the amp, but not the one under my hood. i put in 4 new fuses and hook it back up and , pop, they all blow. i already tried hooking it up in another vehicle and same thing happens. my guess is he let the volts drop to low and it poofed. So what do i need to do to get this fixed. any recommendations for someone on here to fix it. the amp didnt go into protect which kinda makes me mad but oh well. i need to get it fixed quickly. thanks

Those amps are actually pretty durable... I'm surprised. I had a V800XD years ago and sold it to a friend of mine, whom I will call the "destroyer of all things car audio." It took him a year or so to break it... and it only had one blown MOSFET. Oddly, it blew the same MOSFET two more times over the next two years until he finally broke it for good.

Take the covers off the small FETs and check them carefully... that is what went on my friends V800XD. For some reason the legs actually separated from the body of the FET in his amp, they didn't actually "blow" per-se.

Doesn't PEp Boys sell those amps? It will probably cost you more to repair then to replace. JMHO Polo.

alright i will check those. just check to see if the legs have physically seperated from the black FETs?

none of the FETs look to be broken. anyone know of any good people to fix it?
