I recieved my cap in two days and got started and hook it up with two amps. One is a CRUNCH 600.4 (hooked up to 4 Lanzar Componant Speakers) and the other is a JL Audio 500.1 Slash (hooked to my Alpine Type R 12″ SUB). The Cap lit up nice and got rid of my dimming problems for sure. I also didnt realize that this cap is HUGE! So far so good and im happy with it and seems to keep my power pretty solid. IM a happy camper for sure! I think it was worth every penny spent on it.
