I have an Audiobahn 200 watt amp driving 2 4x6s and 2 6x9s, all Infinity Reference. Yesterday I turned my car on and it just cut out after playing about 3 seconds worth of music. Found the 30 amp fuse on the power cable under the hood had popped. Just tested the amp with a VOM and I'm getting 100% continuity between the Power and Ground terminals in the back of the amp. Whats up with this?

Open her up and see what's shorted?

 

Switching FETs are shorted. You have to check there drive circuits too.
