Scosche PSC.5 ½ Farad 500K Micro Digital Power Capacitor Black

I've had this product for over 15 years and it has never put me down when I got rid one of my cars I forgot to take it out so I purchase a new one..........When I had it everyone wonder why music sound so good in my car.

This thing works wonders for my radio, it has helped a lot with the headlights on my vehicle they don't dim anymore when the bass kicks in.

This product works wonderful for car audio. Helps with voltage droping and helps you keep your voltage at 14.4v at the amp no matter what!

This is a great addition to my radio system love it

added so much bass to my subs

works great for my 12" 400watt subwoofer. easy to install and keeps power well!!

The capacitor does as advertised. It helps keep your battery/altenator power above 13 volts during power drains from amplifier. Its very very easy to install and has definitely made a difference in how much the headlights and interior lights dim during power pulls from amp.

It's amazing what a capacitor does to help your audio system.

It arrived sooner then expected

Will do a proper rating when its installed so for now i will EXPLAIN the POINT of an Amp Capacitor. Normally when you have an Amp and Subs connected to it Bass Hits affect the battery of the vehicle, Headlights dimming during moments of high bass for example. The Capacitor acts like a small secondary battery providing enough power to your Amp to either fully or partially stop that from happening depending on the wattage of your system. So not only does it help to provide a "Boost" to the power delivery to your Amp but it helps protect your vehicles battery from excessive power drains, which is what headlight dimming or other types of light dimming indicates. This happening constantly to your vehicle can and does in fact lower the health of the battery in addition to the vibrations caused by the Subs, though how much depends on the type of battery as some can be more affected than others. Hope this helps explain why its important for those using an Amp and Sub Woofers to use an Amp CAP.
