  • Saved my vehicle for the moment
Style: 10 Farad
Headlights were dimming on my vehicle due to too much power from my amp/subs. Finally decided to get this when i noticed it was almost half off on $ale. Took me awhile before actually setting it up. Pretty simple. I just made it complicated then it seemed. Yes it did help tremendously. Hooking it up. ... show more

  • Looks great
Style: 10 Farad
11/6/23 Quality is good, the size is nice, Bright and flashy l have one of their amps so definitely goes well with it as far as lighting. 10 Frag? I'm going with nah but close and if sized properly. Sound quality I did end up with a little feed back after the install and I'm push it to what I believe to be it's limits but i haven't gone after everything with my meter yet but it's small and I'm pretty confident that it's something else.If it turns out to be I will come back and update. ... show more

  • Pretty neat, but be leary of the instructions on this page...
Style: 10 Farad
I like this cap. I like the look of it, too. It's a perfect fit for my application. It's packaged pretty well too. The one thing I don't care much about, but isn't about the product itself really, is the support. Yes, you can get what seems pretty good support, but it's through BOSS AUDIO. Planet Audio on all their products have sub-contracted out the support; which I am alright with that...but it's just something you wont really know until you buy something and have a question. One other tid-bit... If you have never used a cap, like me, MAKE sure you consult the instructions. They did provide them, but before I had really went through them or even taken this from the plastic casing to which it was tied down, I was curious how to charge it correctly. The way it's explained on this page, and shown in the picture is incorrect... they told me, and later when I read the instructions, you must have your (-) wire connected and grounded, and ONLY have your remote wire from the deck connected to the cap and nothing else... The explanation on here is showing only the (+) lead and inbetween the posy wire and they posy terminal of course is the resistor... this is incorrect according to the Tech Support/Instruction manual. As far as function, I've not had the chance to get it rolling. I have a few other components I'm waiting on, and when I get them all together and check everything out, I will revisit this review and post an update. Just becareful.. as always, if it has instructions, read them. Oh yea.. The CAP shown in this picture, is NOT the one you will get; IT looks identical to this one, with one exception; instead of two terminals on each side, the 10F Cap will have only one terminal on each side. The one shown here is the 20F model. ... show more
