hey guys, i have a mazda 3 with factory head, i am running 1200w kenwood amp powering my 2 infinity perfect 10 subs, also i have a 1000w kenwood under my drivers seat powering my front and rear speakers and a set of tweeters, i have soo many wires, how would i wire up to the auxillary so i can just plug in my iphone and go, im sick of cds now haha, would rather not buy a new deck, i had a nice ddin deck but it got stolen. converted factory head to accomidate 4 sets of rcas, should i just get rca/3.5mm jack plug in, will it affect my sound using rca for aux? or should i tap into accessory wire with cd rom wire?
