Hey, I actually bought that sub! The VR3 15-inch 1000 Watt Peak Subwoofer from walmart good sub. It actually sounded good for the 1.5days that I had it.(not lying either) I used it in a 3.6^3 ported box tuned to 34Hz. IT POUNDED FOR THE 1.5 DAYS THAT IT WORKED FOR! I took it back, told them it never worked, and then got my money back! Then I bought a 15" RF HE2! Both subs were powered by a KENWOOD 8101D mono block!
