I recently bought a 2009 used jeep wrangler 2 door.. it had a red cable under the drivers seat that split off into a red and black plug. The cord goes underneath the middle console and then who knows where. They had the boss logo and the dealership said that it was from a subwoofer that the previous guy had before me. So i bought a Boss 12" amplified subwoofer, The "S12A" to be exact.. is this red and black plug all i am going to need for this sub to work?
