Here, we present capacitor that manages to win our hearts. It's the pyle capacitor for sub and it's widely considered as one of all-around great capacitor you can buy. This tool is a very convenient item to have in the box. It comes with a small bag of hardware and a resistor for your initial charge. Hi, this unit will provide the right amount of voltage coming into all devices connected to your car battery. The digital volt gauge works good and looks cool in blue. The voltage readout is nice and is a nice pairing to the sound system. It is obnoxious and never ending. The system has no more drain or lights dimming.

• Highly recommended for anyone who is into subs, and amps that are high powered
• Works well and is very reasonably priced
• Delivers what they promise

Best For Good Price: boss Audio systems Capacitor For sub

Buy on Amazon

The boss audio systems capacitor for sub is capable of outshining several other capacitor featured in this list in overall features for the price point. It comes with a digital voltage display. It will not stop your headlights from dimming when the bass hits, but it will help. It's rated for 2000 watts so it would work fine as long as you are not maxing out your amp. It will also help keep your audio evenly powered and sounding good.

It's a beast and really packs a punch with solid low notes. It does a good job of smoothing voltage going to amps. This includes the power of your system (deck, amp watts, speaker watts) and also the size of your battery. It will work better than just a straight 12v supply.

The capacitor is always, ("on") because it's wired into the charging circuit. It helps with power surges from bass drops. 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.

• Works excellent and no power draws
• Works great with total amplifier power at true 2400 wat rms certified
• Keeps power to two planet audio amps amazing
• Cool looking and adds a bit of extra power to tap when needed

Best For systems: recoil Capacitor For sub

Buy on Amazon

Recoil 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 is a 1000w 2 channel pioneer running at 2 ohms. It improves sound quality for cleaner mids and highs. If you want a good capacitor this one is perfect for 1000 watts or below. It turns off automatically. This cap comes with the resistor board for first charge and easy to follow instructions. It is perfect for systems up to 1000w. They are just long enough to connect the positive and negative terminals, FYI.

• Braided looking metal wire on the block and car body
• Display turns of when ignition is off
• Simple to connect, no signal wire required
• Interior light dimming as they are the most sensitive

Best For speaker: stinger Capacitor For sub

Buy on Amazon

The stinger capacitor for sub is suitable and reliable and fits well with your daily usage. 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. This is a very high quality capacitor, not to mention it looks nice and sleek on any install.

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

Best With stock charging system: T-Spec Capacitor For sub

Buy on Amazon

T-Spec offers a variety of capacitor for personal choice and yet maintaining quality in all the variants. It improves electrical system performance by providing a buffer between the alternator and amplifier. It is great with a stock charging system and really good wire. The package comes with everything you need to install, minus the user having to supply the 4 awg / 4 guage power ground wire. It draws power from the battery. It is also better to be closer to your amp for a shorter electrical run from the capacitor to the amp. The LED screen looks pretty sweet too. It comes with power wires since capacitors are not specific to system wattage setup.

• Nothing too special, just standard clear plastic brackets
• 4 -gauge is a perfect fit
• More dimming lights on the truck when bass gets going

Best For smaller system: stinger Select Capacitor For sub

Buy on Amazon

Compared with other capacitor in this category, the stinger select capacitor for sub has a convenient design. The best thing to get is an adequate alternator with a higher amperage.
