  • Great Cap
Great cap for appropriate output. Easy to install, at a very reasonable price point. Would recommend.

  • Happy
So far seems to be a good product. Didn't have instructions. Couldn't go to website. But figured out how to charge. Works Great.

  • Great value just a pain to install lol
The terminal screws are total garbage and don't support most cables as they are either to small or way to big. Use washers to secure better, I would recommend going to the hardware store for something that's not an Allen hex, stripped out instantly and the wrench was about 2 size to small for the actual bolt, besides all of that, once I installed it I defnitly noticed more clear bass and less headlight dimming, but there is still some . I turn off my headlights as they draw 60 amps and my amp fuse is 2 30A fuses. Kinda equals it out like its not even there lol. No interior light dimming as they are the most sensitive. Oh I never said what I'm using for a amp . Its a 1000w 2 channel pioneer running at 2 ohms . I have 3 difrent grounds. Like your supposed to have it, big tip to possibly make it to where you won't even need one of these is defnitly install a thicker ground wire to your engine block and car body. Its ez to find . Braided looking metal wire on the block and car body. That will help greatly sence its so small of a wire. You can upgrade all your wires and that bs but if you miss that or don't do it, with high enough draw it would fry the ground wire and kill everything else in the car or whatever u got. Not like electrical fire (hopefully not for you anyways) just do your homework and watch alot of YouTube videos to be certain you are sure what you doing, hope it helps I know its hella random how I have it organized ... show more

  • Needed for my application
Installed 800w subwoofer in my side by side. It had a small battery. After connecting this stiffening capacitor the sub put out like it should. Simple to connect, no signal wire required. It turns off automatically.

  • Satisfied
Put this in my Camry for my 2 kicker 12s. For a while the lights would dim and sometimes even turn off. This capacitor solved all of those issues. I was very pleased with the results as the speakers not only sound much better and more consistent, but I used my volt meter and checked availability voltage at the main battery with music all the way up and all accessories turned on, when the bass hit the voltage didn’t even flinch, stayed at 13 volts or above the entire time. Highly recommend for 1000w or less systems. ... show more

  • Gets the job done...
As I suspected, my little 4-banger's alternator just wasn't providing enough juice to power my 1200w amplifier. It was impacting my vehicle's performance as well as my subwoofers. Not any more! l can still see a tiny flicker in the headlights when it hits hard, so I assume this is best suited for systems 1000w or less, but I'm not going to complain because it's a vast improvement. Side note, I thought the terminals had nuts, not bolts, so when I unscrewed it completely after the initial charge it got hung up and I dropped it. They are just long enough to connect the positive and negative terminals, FYI. After hearing "zzzzzzPOP!", I thought for sure I had fried it but I hooked it back up and it charged up just fine. ... show more
