I am trying to sell my two 12's, box and amp. the 12's are Polk and are about 6 months old, as is the box. The amp is Bazooka and runs 500 watts continuous. The amp is about 3 months old. Everything is in perfect condition. I am trying to sell them because I am going to start working on performance on my car and it will just be weighing it down. Make an offer.
