For sale 2-12inch Concept dual 2ohm subwoofers. They are used in good condition. They work great and sound awesome. I just cant use all my amp it is 1ohm stable and can only bridge it to 2ohm. I ran these at a stereo competition with these and hit 148.1db. They were $500.00/sub brand new. I am asking 325.00 for the pair plus 40.00 shipping.
