I have a JBS Technologies 10"woofer w/200 watt amp attached to bass ported speaker box and need wiring diagram to hook it up to my existing sterio which has 4 6"woofers.The attached amp has to be powered and it is missing a fuse and I don't know what size fuse it takes.A friend said to power amp hook it direct to battery but I don't want to risk amp being permanently on and draining my battery without knowing proper wiring procedure.If anyone can be of assistance it would greatly appreciated. Thank You Tony G.
