I recently had a RCA adapter, 4 gauge amplifier wiring kit, 1.2 farad capacitor, 2 channel amplifier, and one 12 inch subwoofer installed. The last step (I was told) was to find an 80 amp fuse and put it in the fuse holder. I was also told that the capacitor was installed improperly. The problem, the amplifier's protection light keeps coming on. No sound whatsoever. The manual said to check for shorts (couldn't find any), and the next step being to disconnect the speaker leads and reset the amplifier (did it and protection light is still coming on). Voltage output is 12.7 with the car off, and 14.4 with it running. Everything is brand new. (Rockford Fosgate 4 gauge wiring kit, Universal RCA adapter, Lanzar Vibe 266, and a Power Acoustik FUBR-12) Any suggestions for this bundle of frustration?
Have you checked the fuses on the amp if you havent replace the fuse(s) with a new fuse with the same amp rating. If you see it's not blown it could be cracked instead of blowing all the way I would still try and put a new fuse in it anyway.
If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.

No wires connected and the protect light still comes on. Do you know how to troubleshoot internally and what the proper readings should be on any given part? I do have some skills when it comes to electronics. And I do have the proper tools to replace a part on the board. And I do have access to get the parts. I would really love to get a schematic, although I expect that would be unlikely. Perhaps someone has some knowledge of common parts that may go bad with this amp.
Thank you,
Its a refurbished amp, just got it in the mail today. I hooked everything up, im posotive that everything is wired correctly. I set the gains to the levels i preffered which is about 3/4 of the max. the amp plays just fine at low volume but when i turn it up i will only run for a few seconds to a minute before it goes into protect mode???
