Bought four of these last spring, keeping two and selling two. Buy one or both, price is for one. They easily pass for an 8 rating, come with a box and will wake up any amp. These are great for instant current demands and will reduce incoming AC noise. Included are the detachable noise stoppers two per cable, leave them off or reinstall your choice. Pictures suck but these are as described and DBS packs show green. Try an excellent PC which is rarely available at a great price. Non smoking house one dog which doesn't mess with things (chewing, peeing, etc.) buy with confidence!
