Audiobahn A12005DN shorting out?

[vimnjicki]

I've had this amp for about 5 years and when I removed it from the last car, it rocked. I run the wires, connect all the safety fuses and ground and everything the manufacturer says to do and when I turn on the HU, the amp lights flash 5 times and shuts back down. No sound, no fire, no nothing. I do have power at the hot side and at the remote turn on wire. It strikes me as a short that the units overload protection circuits are preventing. When I opened it up, there is no apparent problems, i.e., wires crossed or burn marks anywhere. Any information would be greatly appreciated. Thanks
