I want to put 2 10's in my crew cab, but have a few question first. I dont have the bose system would i have to get any adapter to hook up the subs and amp to the stock head unit? Also I may get a new head unitwhat would i have to do to get my all my steering wheel controls to work with an aftermarket head and also could i keep my current xm subscription with that? Also the ipod adapter in the consolewould still be functional as well? thanks.
