I'm a mechanic... so back seat is no problem. I know the speaker is wires with two sets of wires... one for lows, and one for the mid drivers. But seeing as this is a three way speaker I am not sure how it will sound in the back, or if the addition of the tweeter will be a problem. Also if it will work well with the monsoon system... I know on a base model it would be a good upgrade... just wasn't sure on the monsoon.... should I be looking for a 2 way... or will this work good? Sorry... lol
