Customer Ratings & Reviews

It does what I need it to do. Keeps up with the power for my 1000 watt sun amp.

Awesome product for those that are pushing the limits of their factory power supply.

Overall pleased with the quality of this product. Preforms well, the screen is nice. I would like to see better packaging in the future

Good quality for the price. It was on sale and was a steal as far as I'm concerned.

Purchased on clearance for 9.99! Can’t beat that price!

Works amazing would recommend to anyone who needs it

It gave me the continued power I was needing. If you have a system that hits hard enough to dim your lights, this is what you need!

Just needed a little extra something to help with the slight dimming of light and this works perfectly.

Are these really worth it anymore? My voltage still drops and my lights still dim.

Great capacitor, works better than I would have ever of expected and the gains are incredible! It's a must have!

Works well and was easy to install, has yet to cause an issue with my sub

Works great no problems easy to install looks good in my trunk

Love the dual input output for the power and ground the digital read out on volts

Works as advertised. Resistor is very fragile. Charged with test light

Works well and overall made my music experience better. There’s no more worrying about my battery dying. Great capacitor

Great product does if your batter keep on dying. Hightower recommended
