ok so this is for a close friend. He is trying to sell his 12inch alpine type x in a custom ported box. This also comes with the alpine mrp m-1000 watt amp and all the wires to run the system the only thing you need is a headunit. the price he is asking is 450 which is a really good deal since the sub and box alone cost over 700

 

that 1000 watt rms amp?
