The features department is where pyle 3 farad capacitor truly manages to shine. A high-demand audio setup can often place extra demand on your car’s electrical system. It’s got all you need to make sure your system sounds awesome and stays safe. It comes with a small bag of hardware and a resistor for your initial charge. It stays on all night long.

This tool is a very convenient item to have in the box. It comes with two mounting brackets for the cap. It is easy to instal, easy to charge, and keeps the beats coming. The system is loud and never see a problem with dimming lights or anything. It can save your battery.

Why We Like This:

Keeps juice flowing to both amps
Digital voltage indicator is nice and bright
Has built in over/under voltage alarm as well

Best For sub: Bullz Audio 3 Farad Capacitor

Buy on Amazon

Next on the list, we've got yet another capacitor that manages to win our hearts. It's the bullz audio 3 farad capacitor and it's widely considered as capacitor that has the most suitable features. It is great capacitor for both rockville amps db25 and sdb. It connects like the old caps and the resistor is for charging only. It's connected directly to the battery. It includes mounting brackets and allen wrench for tightening terminals.

The capacitor shuts itself off after around 15 seconds after turning off the key. It also has an auto shut off feature and LCD volt meter. It just turns on when the power fluctuates and turns off when it discharges all the way.

Why We Like This:

More grounds is better power loss
Nice clear instructions and easy to install
Good brand reputation

Best For systems: stinger 3 Farad Capacitor

Buy on Amazon

The stinger 3 farad capacitor's superior materials makes sure that it ages well with use. The Stinger SPC505 Pro Hybrid 5 Farad Capacitor is for systems up to 1000 Watt. It comes with a small pcbboard LED green and red resistor to charge the capacitor. It is used to turn on the LED voltage indicator on the top. It is battery, ground, and remote wire input. It does a great job providing reserve power/amp consistency while preserving secondary battery draw when the engine is not running. It also can be hooked up to the remote wire with the head unit. It is a quality cap so it's much stronger than the regular ones. It does have to be charged like other caps, it does come with the resistor circuit board as well.

Why We Like This:

Holds and release charge as needed
You can get more stable and safe while you enjoy your music
Definately helps to keep battery topped

Best For stereo: Soundbox 3 Farad Capacitor

Buy on Amazon

This capacitor is ONLY used as a power current buffer, not as a speaker signal filter. It mounts just like most capacitors and hooks up the same as well. It takes 5 to 6 "one time constants" to fully charge any capacitor to. It is at least 12" to 14" long and the bases have a footprint of 5" or so. This will create a big'spark' as the sudden inrush current to the capacitor is so high.

Why We Like This:

Nickel plated rust resisting post connectors
Good brand reputation

Best With Battery: Audiotek 3 Farad Capacitor

Buy on Amazon

The audiotek 3 farad capacitor should be able to handle its purpose and duties with ease. Capacitors have an extremely low internal resistance to current flow, much lower than that of a battery. Wherever you're on the road with atv, motorcycle, snowmobile and any vehicle, it is extremely reliable and long last stiffening power capacitor you can rely on. It can cook if the power draw from the amplifier or multiple amplifiers demands so much power that the alternator can't bring the charging system and capacitor back up between bass transients, then reduced bass response and flickering lights will again occur.

Capacitors have the ability (capacity) to store a charge on their "plates". This power " reservoir " in the capacitor only works to a point. Capacitors can therefore charge and discharge power much faster than a battery can.

Why We Like This:

Reliable and long last stiffening power capacitor
Good for atv, motorcycle, snowmobile and any vehicle
Good investment for long term

Best For Car Audio: Rockville 3 Farad Capacitor

Buy on Amazon

If you often find yourself scrambling for appropriate and satisfactory capacitor, rockville 3 farad capacitor is your solution. This professional grade capacitor is built to handle even the most power hungry amplifiers delivering a surge of up to 20 volts of power when needed. It features a 3-digit super bright digital led read out which displays the unit’s exact operating voltage to the decimal point. An automatic sleep feature helps the capacitor reserve power during lulls in volume levels, delivering it only as needed.

It comes equipped with heavy duty bolt down style platinum plated terminals which ensure a safe and solid connection. The Terminal for the remote wire in the cap is big enough where you can put another way in it to run to your amp too. It comes with its sleek lines, modern styling and cool blue led accents, and the rfc50f will enhance the look of any sound system.
