Pencil thick power wire may be a culprit. It happened once in my case!

How did you do the Grounding for Amp? Have they made a hole under the boot and fixed it to the body through a Screw? Then possibly that would have rested and you getting the problem. Findout the mounting bolt of rear seat. Remove it and insert a new cable using a proper harness. Connect this Ground to your Amp ground after removing the old cable from your amplifier end. And check your problem got resolved.

Another possibility is the polarity of speakers. Is the polarity correct for all components ?

Remove all speaker wires from Amp end. Take a AAA type battery(Dont use your car battery it will blow off your voice coil ) and connect to the speaker leads. When the voice diaphragm pushing out, the wire connected to the battery +ve terminal is the +ve lead of that speaker. Check all speakers this way and make the connections at amp side. Hope this help.

Reverse polarity wiring will not cause an amp to trip.

My amplifier is going crazy.
