i purchased a power acoustic fubar12w 12" Subwoofer with a Power Handling: of 1800
watts RMS:of 800 Watts and has a Dual 4 ohm voice coil. I've had it hooked up for a while and all was ok. i started putting interior neon's and strobes in..i ran the interior neon's to the positive speaker port and ground port on my amp to make them beat with the bass.. was ok for awhile but now the sub doesn't...
