Best Overall: Soundbox small Car Audio Capacitor

Buy on Amazon

Soundbox has been making feature-packed capacitor for years, thanks to a combination of clever design and high-end materials. The capacitor is a battery for the amp power to start with the car battery. It will kick its self on when you hit with the sub hard enough to start drawing power. It's wired straight to the battery. It is perfect for stabilizing amp flow. It auto turns off when your ignition is off and it reaches a certain level so your battery doesn’t drain. It comes with mounting brackets as well.

It is designed to be used with any amp. It shouldn’t take much longer than 5 minutes to fully charge the first time.

• Great piece of car audio gear
• Keeps the amp and subwoofer from losing power keeping the thump going
• Just an capacitor, like an battery is all its for stores power

Best For almost every needs: pyle small Car Audio Capacitor

Buy on Amazon

The pyle small car audio capacitor's superior materials makes sure that it ages well with use. This amp is top of the range from alpine. It works great with german vehicles with sensors especially if you have an agm battery. It looks great too, thanks to the blue led lighting and the brushed aluminum case. It can only provide the right amount of voltage coming in for both units. It comes with two mounting brackets for the cap. It is easy to instal, easy to charge, and keeps the beats coming. It is good for almost every needs.

• Awesome replacement for a dead capacitor
• Digital voltage indicator is nice and bright
• Keeps juice flowing to both amps

Best For speaker: stinger small Car Audio Capacitor

Buy on Amazon

We know from years of feedback from readers, customers and amazon sellers, what most people want in a convenient and appropriate capacitor. The stinger small car audio capacitor is exactly that - it's a simple capacitor that hits all the right notes. These screw down connectors are way better than the cylinder design. This cap has rock solid build quality, lightning fast discharge, holds it power very well and is adjustable in its output voltage for a massive increase in the voltage stability and stiffening power high current systems need. This allows the amp to run at no less than 14v and remain exceptionally stable in terms of power reserve.

These capacitor loads are a buffer, a relatively large one versus the massive peaks of current demand from large amplifiers and dynamic power comsumption. The charging bulb is incredibly small, comes in a zip lock bag and is very easy to lose. It will stiffen 5000 watts additionally it is always best to allow for headroom.

• Performs similar to a capacitor/battery combo
• Dips in music just solid sound
• 10 farad capacitor for high powered systems
• All power and ground connections need to be soldered and grounds nut and bolted

Best For systems: stinger Farad Cap

Buy on Amazon

The stinger farad cap is capable of outshining several other capacitor featured in this list in overall features for the price point. This product has provided all the thing for charging and installation inside the package, so it is easy to install even if you are a newbie. It comes with a discharging chip and you will no need to charge before use. The power equalizes between battery and cap when charging or between the cap pwr(+ ) and gnd(- ) when discharging. The bass note is long and the capacitor recharges that space instantly where the battery would take about. It also can be hooked up to the remote wire with the head unit. There is a screen and you can dial it in with a small flathead. It is a quality cap so it's much stronger than the regular ones.

• Definately helps to keep battery topped
• You can get more stable and safe while you enjoy your music
• Takes the drain off 2nd batt when engine off
• Holds and release charge as needed

Best For Car stereo: Rockford small Car Audio Capacitor

Buy on Amazon

The rockford small car audio capacitor should be able to handle its purpose and duties with ease. A capacitor will provide quicker power to your amp for harder bass hits and will smooth out the shock to your electrical system but they are not a band-aid for a weak factory electrical system. It allows your system to source short bursts of large current with no fluctuation in voltage. This capacitor is used to regulate (smooth out) the voltage in your system. It helps to supplement your primary battery which charges and discharges at a much slower rate.

There is an insert for 4 gauge that you take out so the 0 gauge will fit. This keeps your system running smoothly and can prevent distortion and electronic malfunctions. This comes with a charging resistor but you will want to stop every.

• Zero dimming and sounds still sound awesome
• Easy install, works great, great value for money
• More dimming lights on the dash
