Rockford Fosgate RFC1D 1 Farad Capacitor

A Must Have!

No more dim lights and great sound quality!!!

Must have piece of equipment!!!!!!

This Rockford Fosgate capacitor is a must have if you are into custom stereo equipment ,there are only pros except for having to buy it that's the only con and even the price was great so that's not too bad !! There's a digital reading that shows your amps which allows you to know when your battery is getting low or if your alternator is about to crash , I had a system with 750 watts rms prior to buying this cap and after installing it i could turn it up loader without my battery being drained and the headlights dimming !!!!! Like I said A MUST HAVE!!!!!!

trusted brand

i have a mrp-m500 powering a 12" type r and im having less dimming and a slight difference of louder bass. if your pushing less than 1000 rms id recommend it. before when i didnt have this cap my headlights and lights on the dash would dim ALOT. now my electrical system for my car runs smooth, my speedometer is brighter and my headlights. but my headlight do dim just a little. btw im running with a stock batt. alt. and no big 3.

Fosgate Performs

This works like a champ! I have this hooked up to a HiFonics 1200 Brutus amp, pushing 2 Rockford Fosgate 12 inch P1's. No light dimming at all. No lacking in amp power ever! Didn't have to upgrade my alternator or battery with this bad boy. And it lights up blue to match my amp lights. Buy this product. Nothing but good things.

Impressive

I am always the one to say alternator, alternator, alternator. However, for my specific application, an aftermarket alternator was not an option. I am pulling roughly 70 amps of current and my 130 amp alternator was struggling to keep up even with the Big 3 in all 1/0 OFC and an Optima Yellow Top Battery. After adding this capacitor, my voltage stays above 14 volts all the time. I guess capacitors only work if you buy the best, rockford is awesome. On a side note, make sure you provide your amp and capacitor with separate grounds rather than utilizing the ground distribution block on the capacitor.

They help when you have a charging system that can keep up

I like to tell people alternator alternator alternator. In my case it's two stock 130 amp 3G alts. 2 mb quart reference amps strapped putting out 1600 watts rms. and I have 2 70x4 amps playing active biamped jl c5 components. I didn't have a problem with low voltage when I cranked my stereo I had a problem with the lights dimming when the bass would hit and the quick spike would come and go making my voltage gauge dance, and my lights would flutter. With the addition of two capacitors the voltage is much more stable. The amps take the power stored in the caps when it hits and the feed of power progressively rolls back in to charge the caps acting like a buffer. If your charging system can't keep up In the first place a cap will not help you.

Never backs down

I've sat in my car for almost 2 hours before with the car off, just blaring my system, and my battery was just fine. My lights don't dim when it hits and I'm pushing 3,000 watts into 2 JL's. This rocks, 5 of 5.

Very good, a little pricey though

This cap is truly one of the best. Built very solid, never had a problem of any kind with it. It is a little pricey, i think, for a 1 F. But if you want the best, and your system isn't too massive, go with this one.

Quality Product

First off it does what it says and is a very solid cap kept my voltage steady and did improve on my bass sound quality the led voltmeter is also very nice. Its easy to install and will fit 0 gauge wire I charged it with a 12v car lightbult like the ones from the taillights.

Overall I would recommended this for small sound systems and to make your setup look better.

Fantastic Performance!

What can I say, this large beast (Don't be fooled by the battery appearance, it's about the same size as my biceps!) has done me well. Never skips a beat, sound is always crisp, clear and precise.

Features: It is a capacitor, has a little LED thing that shows voltage. Comes with capacitor installation kit so you don't turn your fuse box into the 4th of July.
