The 9 Best Audio system Capacitors (2023 reviews)

The audiopipe audio system capacitor is long-lasting, rigid and fits well with your daily purpose like a dream. It's a 6 carat compacitor good for 6000 watt system. It protects your amplifier from voltage surges when you're playing your music loud. It goes between the power source and the amplifier to help regulate the voltage. It's made to hold the power from the subwoofer and to let you know how low is the battery power. It only stays on for a minute after the switch is off.

This one doesn't have a shield over the +/- terminals so if you or anything conductive touches both terminals it will discharge. It will work with the 6 Farrad audiopipe ACAP. It includes digital electronic protection and digital display with status indicator.

Why We Like This:

Very good keeps the head light from flickering
A bit light dimming of course
Great looking and voltmeter works correctly
Holds more than enough power for two 3000 watt amps and kicker box

Best For Car Battery: boss Audio systems Audio system Capacitor

Buy on Amazon

The boss audio systems audio system capacitor should be able to handle its purpose and duties with ease. It is definitely a must to save your alternator in your vehicle. This capacitor is used to hold power for hard driving base so your lights don't flicker. It can turn it up all the way at night with headlights and ac going, no dash lights or headlights blinking.

Why We Like This:

New and hot release
Good investment for long term

Best For few welds: Planet Audio system Capacitor

Buy on Amazon

Compared with other capacitor in this category, the planet audio audio system capacitor has a convenient design. The reserve power supplied by the cap makes a world of difference. It works up too much to 2000 watts of power so it will definitely be more than enough for a 200 watt amp. It reduces the drain of the cap considerably. It's a beast and really packs a punch with solid low notes.

The capacitor is always, ("on") because it's wired into the charging circuit. There's a resistor that comes with it to charge the capacitor for the initial contact then you can go ahead and hook it up. The remote is just a trigger wire.

Why We Like This:

Covers initial charging and discharging of cap
Comes with resistor and all needed hardware and mounting bracket
Good investment for long term

Best For almost every needs: pyle Audio system Capacitor

Buy on Amazon

Next on the list, we've got yet another capacitor that manages to win our hearts. It's the pyle audio system capacitor and it's widely considered as capacitor that has the most suitable features. A high-demand audio setup can often place extra demand on your car’s electrical system. It stays on all night long. This amp is top of the range from alpine. It can only provide the right amount of voltage coming in for both units. It is good for kicker hook up.

This is plenty enough head room to even add more power and no issue. The included proprietary bolt/terminal system is very weak but also quite easily replaced. It is great for a 1 or 2 amp system.

Why We Like This:

Digital voltage indicator is nice and bright
Has built in over/under voltage alarm as well
Auto-shutoff by itself when there is no current drain

Best For stereo: stinger Audio system Capacitor

Buy on Amazon

The stinger audio system capacitor's superior materials makes sure that it ages well with use. These screw down connectors are way better than the cylinder design. It works on 12 volt applications and can generate up to 18 volts if set to that with the power adjustment screw. This allows the amp to run at no less than 14v and remain exceptionally stable in terms of power reserve. The charging bulb is incredibly small, comes in a zip lock bag and is very easy to lose.

These capacitor loads are a buffer, a relatively large one versus the massive peaks of current demand from large amplifiers for dynamic power comsumption. It will stiffen 5000 watts. This is a very high quality capacitor, not to mention it looks nice and sleek on any install.

Why We Like This:

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

Best For tweeter: NVX Audio system Capacitor

Buy on Amazon

The nvx audio system capacitor is capable of outshining several other capacitor featured in this list in overall features in its price range. This is good for up to 1200rms. It can take 0 gauge wire, it also has the reducers for those that have smaller power wires. A capacitor will buffer the current draw and supply steady voltage to the amplifier during dynamic bursts. The meter on the cap does drop to 12v but shoots back up instantly. It can make the mids and highs sound better.

The bass is definitely tighter and more responsive. It more less stabilizes the voltage. It is easy to install and instructions are easy to understand.

Why We Like This:

Keeps the load off the battery for great sub power
Won't stop your headlights from dimming
Good brand reputation

Best For Car stereo: Rockford Audio system Capacitor

Buy on Amazon

Not everyone likes to purchase capacitor for their regular usage, but the rockford audio system capacitor would be an anomoly. 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. They allow your amp to get the power it needs when it needs it. 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.

This is the first version of the battery so, if you are planning to get an extra battery, no need for this. It is good for up to 10k watts. It is really nice looking and with six 1/0awg wires going and coming into it, it looks even cooler. This keeps your system running smoothly and can prevent distortion and electronic malfunctions.

Why We Like This:

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

Best For lower powered systems: Rockville Audio system Capacitor

Buy on Amazon

Rockville line of capacitor come in a pretty wide variety of styles, so you can definitely find one that suits your individual preferences and needs. It comes with its sleek lines, modern styling and cool blue led accents, the rfc50f will enhance the look of any sound system. It features a 3-digit super bright digital led read out which displays the unit’s exact operating voltage to the decimal point. It is easy to install, all power/ground connections are 1/0, and the blue digital display is very bright and easy to read. It's kinda bright but throws a nice glow where it's installed. It will make it feel warm.

This looks great better than the other 50 farad cap, Its heavy in weight looks, well built, simple set up and install. It is good for lower powered systems for sure.

Why We Like This:

Blue illuminated window with light that blinks to the beat of the music
Has a nice volt meter and works awesome
Great quality and great power output
Automatic sleep status when volume is low

Best Battery Capacitor: Bullz Audio system Capacitor

Buy on Amazon

The bullz audio audio system capacitor is suitable and reliable and fits well with your daily purpose. A capacitor is essentially a battery that stores power until you need to use it. The power wire (small wire) to turn on the digital voltage display should be connected to a switched circuit that is off when the ignition/ car is off. It includes mounting brackets and screws and pre charging wire. It works well for the amount of watts it is capable of holding. You will see the volt meter on or off but the CAP stores power so it should stay on. It is easy to get going.

It has stored energy until bleed. It comes with a remote turn on.
