Im on my 2nd amp and it seems to be fine for a few weeks,with no problems at all,then just start doing it again?
Any ideas?

Thanks Mark

Also could you tell me if the factory amp runs just the subs or rear speakers and sub?

Do your speakers still work fine? i am thinking of doing the same in my ute. have considered spliceing into the speaker wiring but didnt want to loose power or quality in the speakers
