I have a 2013 Jeep Wrangler installed the 77 kick 10 speakers and I love them verses stock. I bought the 77KC056 Amp from Mopar it was suppose to be a plug and play install. Vin number said the amp was compatible with my Jeep. I have the base stereo system and I did not realize it had no amplifier to begin with. Does my Wrangler have the amplifier plugs to add the amplifier so I can just plug it in or does an additional harness have to be installed? If so what do I purchase and how hard is it to install? Originally the factory amplifier (as stated I do not have one) was simply to be uninstalled and the new amplifier was simply suppose to plug in an effortless transition except mine has no amplifier to begin with.
