Great quality capacitor. Looks awesome, however it is not a 2 farad cap though. These measured at 1/2 a farad. Regardless these are good capacitors for the price. I purchased 2 and wired them in parallel. Prevents my lights from dimming up to 70% volume then it starts to dim. Its worth it for sure!

This cap should cover 1000 watts, but still has my headlights dimming. Overall it works just need a bigger cap I guess. My amp does not cut out like it would without it, but headlights still dim a little. I would recommend it.

I put a Sony head unit in with a thin Rockville 800 watt subwoofer & it drained my battery in several days.I contacted Rockville & they stood firm stating it was human error on my part for connecting the sub up incorrectly I bought the 2 Farad Pro Audio Capacitor and it works great I also connected the Auto On & Off to the Capacitor and it controls the DIGITAL LIGHT ONLY!! You still need to put an On & Off toggle switch or any switch between the Capacitor & your battery because there is no ON & OFF switch on the Capacitor and when you shut off your vehicle the Capacitor continues to draw power from your battery the same a a subwoofer will. But an on & off switch will save your battery. I had to spend $200 on a new battery & Capacitor. The one thing that shocked me was That Rockville REFUSED to take any responsibility for their sub that killed a perfectly good battery. They have lost a customer for ever!!!!!’Read full review

This capacitor is not anywhere near enough to make a difference in even the smallest of amp systems. Don’t waste your money on this product like I did. Save your money and get the highest farad capacitor possible if you want to notice any difference at all. Looks quality built but just doesn’t make a difference. It discharges within about two minutes if disconnected. Don’t throw your money away on this.

I recently added a 120volt/12volt AC transformer to my stereo system in my workshop. I had a 1/2 farad capacitor in parallel with my bridge rectifier and was still getting some feedback from the transformer. This capacitor totally took out the interference issues and left me with clean crisp sounds of awesomeness!! I'm very happy with my purchase!!
