Don't know what to do!

Hey all I've got a Lightning Audio X1.1000.1D amplifier is not working. I opened up the case to find a few mosfets blown so I purchased them online and replaced them myself. Everything else looks perfectly fine. I hooked up the amplifier and it blows all 3 (30 amp) fuses every time. The wires are all fine, nothing is shorting, I can hook up a different amplifier and it works fine. What else typically goes wrong when mosfets blow?

This is initally what happened: I was playing music (loudly) with the gains slightly up(oops? and no it wasnt completely cranked) and it sounded great, then it cut out and came back on a few minutes later - only it was much quieter and sounded weird. At first I thought something was wrong with my Memphis PR 15's but obviously that is not the issue. Then the amplifier blew all the fuses and that was that. I've looked the board over very closely but can not find anything else that could be wrong.

Anyone have any ideas? I'll put pictures up asap. Also, as a side note, could it have been because of a voltage drop? It's very possible my electrical is lacking.

This was an incredible amplifier, it put out some serious power, I hate seeing it just sitting in a box not being used!

Thanks for any and all input - it is much appreciated!

Actually it didn't have a warranty to begin with but thanks for the helpful response.

As a matter of fact, because it had no warranty, they wouldn't fix it period, and the insides looked as if they had already been repaired before.

Yes, we can really tell what's going on with that picture...

Unless you have the proper test equipment, send it in. Search for db-r on this forum or go to www.db-r.com.

Obviously you can't tell what is going on in the picture... it was more or less to show the internals in general and somewhat the layout of it. I said that I could not see anything else wrong with it. By posting the picture I did not expect anyone to literally see the problem. thanks.
