and im very, very pleased with it. i had nasty voltage spikes to the point where the music would cut out and i would have to turn my car off/on for it to start again. now that i dropped a red top in, my voltage is oh so stable (and i haven't even done a big 3 yet). i should also add that im only using a 600 rms, so im anxious to test it with 1200+ watts
