I got a kicker in few days ago, it's one of the smaller "ZR"s (slide-in module)
I can't find the model # on the unit. Must be on the plastic side-piece that's missing.
It keeps popping the little surface mount signal ground fuse on the under-side of the circuit board.
Last time I replaced it, the amp worked great on the bench until it was reinstalled in the car. Then, it popped again.
I just replaced the fuse again. It worked fine on the first test but when I hooked it up on the bench again, It popped once more.
I can believe that the customer may have a signal ground-DC ground offset problem, but I don't on my test bench.
(This amp's case becomes signal grounded when you bolt the board in so I could easily believe that the case may have touched
the car chassis. But not during my test)
There were no markings on the fuse, so I've been using a 1amp pico. Is that the correct size? do I have a problem elsewhere ?
Here's some pic's of the board.

Appreciate any advice.
