Regular batteries are not capable of putting out the power needed for those heavy bass hits. An audio battery (such as those manufactured by ) can keep up. I replaced the main battery with a full size stinger battery, and tucked a smaller stinger battery behind the back seat.
Agreed, they are more of a accessory, than a necessity.
I already had my wiring upgraded, and had no need for a high put alternator,so that is the only reason I got the cap at the time is it looked cool, and to relieve a little battery strain at night when using my lights, now if I had the equipment I used to have, I'd probably spend that 360.00 along with a little more cash on a Stinger battery and a 200A relay isolator, put that in the back, and upgrade the alternator to a 200A with dual rectifier bridges.
