I was thinking about installing amps and subs too, i have 2 alpine 10s and an alpine amp. Im just kind of worried about if i ever have a issue with my head unit or something that theyd say its because i spliced wires....
you dont splice at the head unit. the wiring harness travels along the passenger side of the car to the trunk. from there you can make the tap, assuming this is a shaker system. much easier and less wiring to run.
