Look up the owner's manual. It shows the code for the flashes.

the 3 flashes means that the battery is bad, since I'm working
with a 12V 35amp power supply, I decide to look for loose power supply
connection, and founded a loose transformer, tight up and the amp
power came up, install all the output transistor, and the amp was
playing OK for about 2 min, until I disconnected the remote cable,
I heard a spark and all my output transistors went bad, any suggestion?

Thank very much, solder the power connectors, and the area
and that did it.

fosgate power 1000.2
 
this amp got 54v on one channel, no shorted
output or drivers, the tl072 have the +15v
at pin 8, and 6v at pin 4 instead of -15v
any sugestions?
