No more dimming lights and rev problems with the engine. When the bass hits the engine would drop some RPM's while idling, but not anymore. Voltage goes to 13.5 and 13.1 when the bass hits. I have a 420w rms mono block along with a 70w x 4 rms amp. Not much, but enough to dim my lights and get the juice my engine needs. Installation was a breeze. Charging the capacitor was a pain. After 1 minute the resistor started smoking, and had to stop for couple seconds to let it cool. And after 10 minutes the cap was still at 8 volts (Using a multimeter). Would recommend getting a better quality, lower resistance resistor to avoid losing half your day charging it.
Overall: Perfect, works as intended
