well guys the thing about power caps usually people install power caps to stop any fuses in the car melting
and always use good wiring for better sound quality
also always run the
live+ separate from the (RCA cables and the
remote cable) ideally run the RCA cable and the
remote cable together and run the
live+ by it self
always makesure that the amp is properly mounted and all the wires connected to the amp terminals are screwed down securely and if you can use heat shrinks on the connected wires to the amp so any lose bits of the wires don't touch any of the other wires.
also make sure you insulate the RCA cables and the
remote cable together with insulation tape
