Its a Kenwood KAC 8105D Amp that says RMSx1 at 4 OHMS Max W 1000 and it says 300 W on it too. I only had all this for 2 months and It was wired to two Kenwood KFC w3013ps 12 inch subs that pushes 400 RMS W peak level 1200 W. DO I NEED TO BUY A NEW AMP OR CAN THIS BE FIXED? THANKS

not worth fixing IMO

I wouldn't fix it you could buy another by the time you ship it and pay for repairs

Looks like at least that one mosfet is blown.

Replace fet. Looks to be a very simple job on that board.

you can fix it, those fets are about 2 or 3 bucks, hopefully you didnt burn the traces though. you will also need 2 drivers and possibly check the gate resistors. I dont think it is worth your time though.

Like was stated before it's not really worth the money to repair it unless you just want the experience of repairing it. You have some blown power supply fets there. There is also a good chance the outputs are dead too even though they look totally fine. Output fets don't normally blow apart when they die. Could very well likely cost more than the amp is worth to repair.
