The best way to hook this up is find a good car battery....you can pick up a used one at an auto salvage yard for 10-20$ if you don't have one laying around ...then wire all your car audio up to it like wiring to a car....you'll want to keep the battery charged so after hooking it up take an old electrical cord...and strip back both of the spare ends and hook them up to the battery...plug the plugged end into the wall to keep your battery fully charged....you won't have to worry about which end is pos or neg like in a car because it will be AC voltage so either side will work...//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I hope this helps to get your system rocking.....//content.invisioncic.com/y282845/emoticons/peace.gif.2db28b618ed8d1964ebbe2f5021d2c39.gif
