Up for sale is a hardly used boston acoustic g5-12 subwoofer. I had this in my Z then another box in my excab. I still have it in box for xcab but combined weight is 74lbs so shipping would be rediculous expensive so Im just selling sub. Looking to get $250 OBO shiping depends on were you live. click link below to look up specs and such on it. 900 watt peak 400 rms dual 4ohm coil all the rest is listed including VAS and all othe specs.
