Wire it yourself. I just did mine.I have a gladiator sport, and what to add a subwoofer behind the back seat, are these prewired for subwoofer, or would i need to wire it myself?
No, not really. Just a little time consuming and a lot of steps. I put a powered sub behind the rear passenger seat. I took the front passenger seat out first because under that there is a rubber grommet that you can drill through to run a power cable to the battery. Also there is a factory ground post under that seat just below the center console on the transmission tunnel. Or, despite some contrary opinions you CAN ground to aluminum at the seat bolt as long as you clear some paint off.was it difficult?
