I have an MTX Thunder 3401 amp and it shut off on me this weekend. It still gets power but the short light just flashes anybody know how to fix this or is the amp finished?

is it running hot when it was running? check to make sure your ground is good and the fuse is good

It has a fan and the fan is constantly on now. all the outside fuses are good as well as the ground.

hmmm. sounds like it might be running hot since the fan is constantly on. is this still underwarranty by chance? if so i would send back as there might be something internally that's causing it to run hot

Nah not under warranty. I think I might try to remove the top and see if there is an internal fuse that is blown. I had power off of it for 2 days and as soon as I powered it back up the fan kicked on. Kinda weird.

Looks like the amp uses a special Torx bit so I'll have to go buy one to open it up. This sucks!

check your grounds as said before. also check your remote and power leads.

The only thing that should make an amplifier heat up that badly is if you are using an impedance too low than designed for that amplifier. make sure the speakers or sub it is powering have good connections and are loaded properly to the amp
