Car amplifier distortion is the chief cause of car subwoofer failure. (Distortion is a speaker’s greatest enemy. Also a car amp may distort prematurely if it is starved for current and voltage. Too small a cable will reduce the power getting to your car amplifier and thereby reduce the amplifier’s performance, causing it to overheat or shut off. In car wire gauge sizes, the smaller the number of the gauge, the thicker the wire and the more current it will carry over a longer distance with less loss due to the internal resistance of the wire itself.
