Súper buen producto, es mucho más grande de lo que imaginabaExcelente calidad!!Llego muy rápidoEl proveedor 1000% recomendado😎👍

One turned up rattling, managed to get the part out, haven't wired up yet but looked like a component so we will see

Take your time and use good quality power and ground cable like sky high audio OFC 4 GAUGE wire for power AND grounds. Great wire don't hesitate VERY flexible but always get a extra 25% of length no matter what wire you use think Is enough!! Capacitor was packaged ok inside planet audios MANUFACTURERS BOX NO FOAM INSIDE JUST CHEAP PLASTIC MOLDING ATTACHED BY WIRE TIES INSIDE THE CAPACITOR BOX! MADE ME NERVOUS......as a electrical component especially! Gave it a shot. I have installed many amp subwoofer combos but never a capacitor. As normal hook up your GROUNDS TURN ON WIRE TO THE CAPACITOR AND AMP. CONNECT YOUR POSITIVE OUT PUT OF THE CAPACITOR FIRST !!!!NOT INPUT TO CAP YET!! Now Using the included RESISTOR put one end into the bare POSITIVE wire coming from your battery to charge the capacitor. Now don't be scared! Plug the other end of RESISTOR to CAP INPUT. Make sure cap POSITIVE input terminal is screwed all the way down. Make contact and hold it the voltage will rise ... Mine only took 40 seconds the constant beep will stop to let you know when its done charging!! Plug in POSITIVE terminal like INSTRUCTIONS SAYS!! What a difference the constant power made!!!! For the constant clean power it fed! Sound quality GREATLY IMPROVED. VERY GOOD FOR A STOCK ALERNATOR AND BATTERY BECAUSE IT WOULD BE UNDER STRESS. WITH OUT THE CAPACITOR!! Works GREAT WITH TOTAL AMPLIFIER POWER AT TRUE 2400 WAT RMS CERTIFIED!!

It showed up on time and it works amazing really good price for your bucks. No more light dimming and it looks really nice thanks

I want to start off by saying that I'm almost certain that this capacitor is nowhere near 20 Farad, then again it is UNDER $100, if your looking for a true 20 farad cap then your looking at the wrong price level. Now while rating is BS, the product itself works wonderfully and does exactly what I need it to do, my lights no longer dim when my bass hits, nor does my amp switch into protect mode because of severe voltage drop. I'm running an L7S15 wired to 2ohms on a kicker IX1000.1 amp in a ported box with stock alternator, big three wire upgrade, and an optima red top battery(any other questions feel free to ask).-I have no issue with the voltage display screen that other reviews mentioned.-noticed it does take about 30 seconds before it shuts off after I've cut vehicle off.-20 farad cap is the easiest to wire in, I literally tied it in my existing wiring as it has a positive and negative in and out(be sure to follow initial cap charging instructions during install they're in the booklet that comes with it) and I just ran a wire from my amps remote wire to the cap so they always cut on together
