I got a Powered sub with a built in amp didnt come with wires but i have everything from a amp kit bought seperately. Doesnt have a spot to put my groud or power wire just says 6 pin12v rem gnd and a blue thing that says 12v fuse? What do i need to buy to install the sub its looks like a bazooka sub. I looked up the 6 pin thing and its called a molex i think but thats for computers im really confused and new to subs. i bought it from craigslist so im stuck with it so please help!
