Rockford Fosgate RFC10HB

There is a lot of controversy surrounding capacitors in car audio and if you are running a big enough system to warrant a capacitor you should probably be upgrading your battery and alternator as well as doing "The Big 3." That being said, I purchased this simply to level out the load placed on my car's electrical system (one constant load rather than a bunch of big ones) and to hopefully provide a little extra juice to my amp. If it reduced or eliminated headlight dimming then that was just icing on the cake.

Charging took a while, I stopped to let the resistor cool many times but when it finally got charged up I pulled the sides off (very stiff, be careful not to break anything) and attached it to the backside of my box and got everything wired up. I was blown away by the difference it made, I got a ton of extra bass and it was much tighter and more precise than it was before. I waited until dark and took it out to see what difference it would make in my headlights with stock alternator, normal battery, and The Big 3 done and with my high beams on and the volume all the way up I could not see any dimming. I let it idle to see if the drain would dim the lights when the alternator was not putting out as much power and I still did not notice any dimming. My Boston Acoustics GTA-800m used to dim my lights pretty bad, especially at idle on high beam, and now it doesn't seem to be an issue.

I bought and tested this cap as objectively as I could, I had no prior bias as to whether or not it would affect sound quality or headlight dimming and from what I have seen in my own car I highly recommend this because it gave me much better sound quality, more powerful bass, and it eliminated my headlight dimming. It seems expensive until you see and hear the results, then it becomes a bargain!

I had previously owned a Rockford Fosgate 1 Farad Capacitor of which I was thoroughly displeased with. I was also thoroughly displeased with the RFC10HB after I hooked it up as well. However, after tinkering with it, I found that I had hooked my RE-Q5 bass restoration system's power wire up to the outgoing power on the capacitor. Therefore it was getting vast peaks and valleys in power input. After I fixed the wiring I was blown away. It sounds like I have a new set of subwoofers. Much more accurate and rich sounding than with the 1 Farad. Also, I went from significant headlight dimming to none just by hooking it up. I'm not exactly sure why, and I've heard may people say that capacitors don't help with that, but hey, I'm not going to complain. As of now I have a stock alt, stock batt, and no big3 done. I would probably leave it that way too, if I wasn't planning on upgrading my amplifier. Shell out the extra money for this capacitor if you can. I paid 100 for my 1 farad, trust me... spend two times more and get something ten times better. You'll want the upgrade in the long run anyways.

I have had this capacitor for about 8 months now and I can say this thing is awesome. I bought it for 60 bucks off one of my friends. Immediatly after installing it my bass was LOUDER and CLEANER than its ever been. Love this thing! The volt meter is great too. But dang the price is a lot!!!!

First off, I am a Rockford Fosgate fan. I own two Rockford Fosgate T-600x2 amps. They are pumping about 775 RMS a piece, for a total of 1550 watts RMS. That leads me two the two Rockford Fosgate P3DV4ohm 10's. I had already upgraded the Alternator, battery and wires. I was just really interested in getting a power source that would give the two amps steady amperage loads to stress the amps even less. This did the trick!!! I am running 1 gauge wire by Tsunami. Kinetic battery. Not the loudest system out, but enough to smash most.

Honest company. Thanks for the greatest price around.
