The wiring is not likely to be there. You will have to remove panels and investigate. It has been reported in other threads, by those wanting to add other options, the wiring is only included in the harness if the option is ordered from the factory. The sound system may be different. Check with Crutchfield and see what they have to offer.Ok guys I need some help...I am wanting to install the factory premium sound (sub and amp) in my JT that did not come from the factory with it. Do you guys know if the wiring will be there from the factory or how I can get this done?
I would think that it should be a good addition. I have the factory installed Alpine Premium system with the sub behind the back seat. It sounds really good to me, but I'm not any kind of an audio expert.Yeah that's what I was afraid of. Any thoughts on the Alpine PSS-23WRA system?
