"DO NOT USE SONIC ELECTRONIX! They sent me a used 12"Alpine Sub enclosure. First they blamed it on shipping. Was wrapped in plastic, completely covered in Styrofoam, and covered by not 1, but 2 boxes. Clear by scratches and chips on bezel, that it was a used sub. Could hear clunking in box. Hooked it up, didn't work. Checked my connections on another speaker, worked fine. Countless emails and phone calls, they wouldn't return my money. Out $450CDN. Scam artists. DO NOT BUY FROM SONIC. You'll be sorry"
