So, I have a 2007 limited DC with the JBL upgraded system. I am installing a new headunit and getting a new amp and subs. My question is the stock wiring harness doesnt fit the JBL upgraded wiring. I bought the headunit from another member on this site. I know that to use the JBL amp and sub you have to get a bypass but since I am getting rid of those and only want to use the speakers then want to i need to buy? I'm still looking for subs too, so if anyone has a pair of tens that what to let go I'd purchase them, really liking the sundown audio 10's. Thanks for the help.
