So I just have one quick question and can't seem to find my answer (yes I used the search!). I've been reading about subwoofer installs in the Mach 460 system using the line out converter method by splicing into the data cable, but then realized that this method is for stock headunit. I have an aftermarket Pioneer deck, would I still need to do this method or wire them how I normally would using the Headunit's RCA ports?

All I needed to know! Thanks a lot!
