For sale 2-12inch Concept dual 2ohm subwoofers. They are used in good condition. They work great and sound awesome. I ran these at a stereo competition with these and hit 148.1db. The amp works great, it is a powerful amplifier and it is clean power. The subs were $500.00/sub brand new. the amp was 700.00. I am asking 600.00 shipped for both.
