Rockford Fosgate RFC2D

I recently order mine from Sonic. Got a great deal on it with the make an offer option. Seriously not alot of sites have it, really cool and definitely worth the price. This ROCKFORD FOSGATE capacitor is the best-selling one on this page. Bought mine a couple weeks ago when it was limited stock. Checked a few days later an it was in stock, an a few days after that back again to limited stock. WOW they speak for themselves. Overall the capacitor is clean... THE BEST THAT MONEY CAN BUY.

This cap is AMAZING. It helped the drain from my battery, and my head lights dimming. I love this cap, because it helped me not have to do a lot of upgrades in my car. If you are looking for a great cap worth the money. Well, you found it.

I would highly recommend this cap to anyone considering a system upgrade, I am very pleased with the performance of this cap, the amp seems to have loads of power to when the low frequencies and transient highs are presented most of all no dimming of headlights. Good work Rockford, nice looks as well.

Like all Rockford products this one all so full fills its duties. I have never had any problems with it and the price is not bad. All u have to do to have a great system is get rid of anything that is not rockford, and replace it with Rockford.

I have this capacitor hooked up to two 12" Alpine Type R's. With a Alpine MRP-2000. I had a lot of dimming before I got the capacitor so I decided to buy this one.
After I got the capacitor all I can say is WOW, you could tell right away that the Subs hit harder and louder. They also hit notes and the sound would last longer before going quiet. The cap itself looks really cool and is built really solid. The mounting brackets are plastic but as long as you mount it in a good spot it will be fine, the digital display also looks really good.
I also have a optima yellowtop battery and a high output alternator. If you have a capacitor and you still have dimming its probably because your alternator isnt putting out enough power.
