The SKB 1x12 Amp Utility Vehicle (1SKB-R112AUV) offers the same protection and convenience as our larger 2x12 Amp Utility Vehicle (1SKB-710). Amps are held in place on a rugged rolling hook and loop fastener board with four of our patented adjustable corner cleats and a secure reverse-cinch belt. When the amp is in use, it can sit securely on top of the cover at a height that allows better sound projection.
