### ⭐⭐⭐⭐⭐ Works Great!!
*by P***O on March 19, 2024*

I really like this product, I bought 2 15inch Kicker L7 so I needed something that could help with the power plus with the 8k Amp. I like the blue color that lights up on it an the fact that it makes a "beep" sound when you turn the car on so it let's you know everything is good to go!! Couldn't of asked for more, thanks...

### ⭐⭐⭐⭐⭐ Rockville awesome products
*by B***D on May 14, 2018*

So I use lots of Rockville products and I will say that I absolutely love each and every one of them and for the money you can't ask for anything better and any time I build any stereo I guarantee there is Rockville all threw it but getting to just the capacitors, they do their job very well as a capacitor not a substitute for a second battery or a high output alternator like people try to do but awesome as a capacitor hope this helps anyone on the fence about getting one for their system but used probably the same can really help improve your system and prolong all the electrical in your car for those bass heads out there.
