Works Great!

I bought the T-Spec V8 so that my light would not flicker anymore. Not only did it do the trick, but now the bass from the sub sounds even cleaner! It also looks pretty awesome. I would recommend it.

you get what you pay for so choose wisely

Works as expected. T-Spec makes quality products.This cap is a perfect match to feed my Kicker 1200 watt mono block.

Won't disappoint.

I have owned multiple brands of capacitors and this one has helped regulate my voltage much better than my old rockford and boss audio capacitors. It looks cool in the trunk and has helped my system a ton. The only downfall is that the voltage display tends to turn off for a minute here and there but then it comes back.

Works Great, Looks Great

Im running 1500 watts rms on a Hifonics amp and noticed my headlights dimming when it was cranked so I decided to buy this even though everybody says Caps are a waste and don't do anything but this thing made the dimming lights go away so I'm satisfied. Caps don't really make the subs louder just improve the amps voltage so you recieve a cleaner signal. Anyway the distribution block on this thing is why I bought it and makes the install a hell of a lot easier! Overall 10/10 no problems. Thanks

T-Spec V8-3DDC

The capacitor works great, reduced dimming of the lights on my boat while paying the radio with the solo 15. But received the capacitor with the outer wrap ripped and scratched up. Didn't want to wait for replacement so tour off wrapping and went with it.
