sub randomly cuts out then returns?

Still baffled as to why it did not show up in the first few months of you having your system though.

I tend to shy away from circuit breakers due to a voltage loss often seen under load.

Slightly off topic, But:
Why are we all using fuses?

I don't trust circuit breakers. Dual 150A fuses did the job and blew when they should

Maybe it took 3 months for the cable to be damaged. Mine took 2-3 before it started doing the same thing as well. Then I turned it down and can hold bass for longer before shutting off. But prior to that I was using the same cables for 3 years with no fault. Maybe the build up of heat has caused issues with the wires inside the insulation and can't carry the same load anymore. Maybe as an experiment try running new 4ga wiring just around the outside of the car to make it easier to test instead of going through the fire wall. Then turn gain back up and crank it. See how long it takes to cut out. If it does then it's something else. If it doesn't, you found the problem. Wiring needs to be replaced with the next thickest one.

so jay87 was right. dunno why but i ran a thicker wire round the out side of the car and did a few tweaks and it was thumping fine so i swapped over all my power wires and put a bigger fuse in etc. everythings fine now. cant see any obvious damage on my old power cable but it mightve had some internal damage or something.
even found a hole in the floor from the old owners wiring so i gave that a quick dodgy patch up to stop water coming through. after all that i just needed to swap a wire D: hopefully it doesnt go to **** again hey!
