Kole Audio C4D (C-4D)

This cap gives me enough power to drive my 3000w boss amp and 3000w Blaupunkt sub, even with the volume turned up to max the voltage only drops to 11.9V from a max of 13.4, my charging system isn't very good otherwise I would be getting more out of it

Works as expected but plastic case is cheap feeling for the money.

This is a good product, it is kind of huge too instead of the usually average one of 1 or 2 farad caps. I appreciate the blue lights and the fact that it is chromed. It gives my trunk a new look: flashy but efficient. It does what it is supposed too and keep a low profile when the music is not in bass mode. I recommend this product for its look, its quality and for the price of course: Thanx S.E!

Easy to hookup, looks nice, got it hooked up in an rx8 stock electrical (100amp alt, duralast gold batt) with a kenwood 1800watt peak 900 rms amp, engine running idle it reads 13.8-14.7 with volume nearly all the way up. Only thing i dont like is how bright the lights are at night other than that its a great product.

Great looking product. Does its job quite well. Keeps the bass levels nice and tight at all times.
