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.

very happy

install was very simple and works well with my Rockford T1500-1!

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

OK Cap

Good product for systems under true 1500 watts rms, 1500 watts or over look for a different cap or more than one of these, I would say this cap is mabe 1 true farad or a lil over

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.

Does exactly what it says it will do.

Just connect it and go....I have a 2000 watt amp and 2 JL W3 shallow mounts and it turn on every time like clock work when the bass hits...

Better with this than without!

I had a big problem with the amount of power my amp is drawing. I bought a bs cap from a store and still had big problems. I got this cap from sonic electronix and the power draw is not as bad and the sound is way more clear.i will be upgrading to a five fared or larger cap to properly correct the power draw. Excellent product for the $ just not enough for the beast amp i have. Will recommend for someone with a smaller amp.

Great investment

Noticed instant results when I installed this lights no longer dim and bass is louder!

T Spec V8 capacitor

This is my first experience using a power capacitor in my system. It definitely takes pressure off the battery and makes my Subs much cleaner. I don't have a competition set up so it does take up additional space in a family vehicle but not much and definitely worth it.

T-Spec V8-3DDC

I like the multiple connections for POS.& NEG. The Capacitor seems strong and the built-in voltage meter is a plus. Price and name sold me!

I love this product.

I would definitely recommend this product for your sound system. My lights do not dim anymore when my subs hit.

Great product.

This is a great product. As soon as I hooked it up my lights stopped dimming.

Nice cap. Nice price.

I replaced a 1.5F cap with this one. This one has more capacity and it shows. My light don't dim as much and my bass sounds more powerful.

Excellent

Got rid of my headlights dimming, ultimate pro: was able to use it as a junction block for my 0/2 wire. Cons: none yet

Great Value

Works great fits in small places. We buy again if I needed to.

Excellent

I am running a total of 6400 Watts (that's what the amp manufacturer says, it's less) my lights would dim extremely on heavy base. I had done the big 3 which made a huge difference but still dimming lights at half volume. My sentra charges at 14.6 and at 3/4 volume I'll drop to 13.1 without dimming (I used the same song). There are those that say caps are useless, I'm sold. This has worked for me. Plus it looks killer mounted in trunk. Now I can rattle my car apart one song at a time. No complaints with this product. Heavy gauge in and out was a plus.

Great price for product

This was a relatively newer capacitor style and for the price it beat most other competitors mark up on it... saved me 80 bucks over others great deal thanks

Great Buy

I purchased the T-Spec-V8-3DDC capacitor for my truck and I'm very satisfied with my purchase, after doing some research about the different types of capacitor This particular model caught my eye and i didn't know they made capacitor for V-6 and V-8 engines specifically and it was very easy to connect to my existing system after removing my old 1.0 fared capacitor I must say I'm very impressed with how well my system sounds after adding the T-spec-V8-3DDC it handles 3,000 watts very well I recommend this product for anyone who's looking to add a 3.0 fared compacitor for V-8 or V-6 engine.

Update on The Water

Just what the Cap-Dr ordered. Added to our overall upgrade and all is wonderful.

Does it's job

It does it's job, looks good, super easy install. I real like the enclosed top, less likely to end up accidentally shorting out. The double terminals also make the install simple. Unfortunately it did not help subside with dimming of my lights, is actually made it worse. Although the bass is a lot cleaner and harder now. Looks like I'm of to upgrade other areas of my electrical system to feed the needs of my sound system.
