I would encourage you to utilise the power of both amps. You wouldn't be able to effectively run 4 speakers and a subwoofer off a 4 channel amplifier. That JL sub is very decent and deserves the power that Kicker mono is putting out.
My advice to tidy it up: Invest in some decent Stinger accessories like a power cable splitter block and find ways to creatibely mount it.
Other then that, nice work in progress, mate. Bet it will sound great when you have it set up.
i already have a power splitter, their hooked up, just need another set of rca an longer wires to hook up the front speakers, right now the sub an rear an both amp works, guess i have a lot of tidying to do thanks anyway
