I am selling an InterFire Pro v10 subwoofer. It is basically the exact same speaker as a JL w7. It is the loudest sub I have ever owned but I now have a baby and it must go. The sub retailed for $350 and I am asking $150 plus shipping. I also have the amp that ran it for sale. It is a 1250 watt Power Acoustik BAMF series amp. I am asking $100 for the amp. Both were only installed for about 4 months. The sub is basically new and the same for the amp but it has a few scuffs on it. PM me if you have any questions. $250 can get you a whole system. If you have never seen these speakers in action then please do your self a favor and look them up on youtube. You will be amazed!
