Excellent Product. Excellent Price.

I have had this capacitor for 6 months and its functioning perfectly. Absolutely no problems. My headlights don't dim with the bass anymore.

Unless I'm bumping my beats loud enough to bother the whole country of china.

Bigger than expected

in the pics it looks like about the size of a soda bottle or something and thats how long it says it is, but it is massive for a cap. it is more the size of between a 2 liter and 1 litre bottle of soda, but it gets the jobe done and does it well. it powers my 4000 watt power acoustik amp and powers it well. my dash lights and headlights never go dim. they always stay constant even while im bringin the juice.

Boss Cap4c is pretty decent!

Bought this cap and im running 3800 watts and i still have some light dims but nothing major if your gonna be running like 2200 watts RMS or less i think it can most defiantly do the job i still would recommend a dry cell but over all great buy for the cash!!!

satisfactory

Good pruduct for the money.
I have a 1000wt momo block D amp with 500rms on 2 1000wt 250rms subs and a 600t 4 channel amp on my mids.
Lights don't dim any more unless I try to max it out, but I grounded my altenator better and it solved it.

Great product

I got this capacitor for christmas and have it running two rockford fosgate p3d2 2ohm subs and I love it. The light behind the digits is bright, but kind of adds to it. I have actually got several compliments on the way it looks as well.
