Product Research



Overview: The overall response of your audio system will be enhanced with the use of capacitors due to their ability to store a large amount of current and discharge it quickly to supplement your amplifier's power supply during high current demand (bass note). The Tsunami capacitor is a logical addition to your system due to the fact that automotive batteries aren't designed to deliver the current to satisfy the requirements of high powered audio components. It can also filter AC voltage induced in the system by the amplifier's power supply which could cause objectionable noise. One Farad of capacitance is recommended for each 500 watts of amplifier power, but you can never have too much capacitance for any system.


Display: There is a digital charge level indicator display. The digital display shows your precise voltage in 0.1 volt steps.

LED Ring: Once the capacitor is charged, ten blue LEDs around the base of the terminals light up.

Chasing LEDs: There are two rows of two blue chase LEDs that pulse with the charge/discharge cycles.

Audible Voltage Warning: If the voltage drops below 10 volts or rises above 17.5 volts the capacitor emits an audible alarm.

Sleep Mode: After a few minutes without any load (with the amp off) the capacitor enters a sleep mode; all the lights turn off to avoid discharging the cap, and subsequently the car's battery.


Installation: On the top of the capacitor on the right side are three positive terminals. These terminals are shorted together, so they are interchangeable, one is connected to the battery (and fused at the battery), the other two to the positive inputs on the amps. On the top of the capacitor on the left side are three negative terminals. These terminals are shorted together, so they are interchangeable, any of them can be grounded to the car's chassis. The positive and negative terminals are set screw terminals, each sized for 2 gauge wire, but they're shipped with a removable insert sized for 4 gauge wire. Before the battery is connected you must charge the capacitor with the included light bulb.



  • Capacitance: 2 Farad
  • Maximum Operating DC Voltage: 20 volt/24 volt surge
  • ESR (Equivalent Series Resistance): < 0.002 ohm

Great Capacitor

Written By Crutchfield, Slidell, LA on Thursday, July 23, 2009

Crutchfield Customer Review (What's this?)

This capacitor is great for those running a high powered system, but you may
need to go bigger depending on the setup of your system. I am running about
1500 watts for my system and it seems to get the job done. The blue accent light
is nice as well as the triangle design. I am very impressed with this unit and I
would defiantly recommend this to anyone who doesn't want to burn up their
alternator or battery.

Good Product

Crutchfield Customer Review (What's this?)

I have this cap pushing power to an A600.1 amp that power 10 JL w6 10's. After installing this cap I noticed a cleaner and more accurate bass response which is pretty good for the price. Install was a breeze, product is great, looks cool, but the only con I can see is the cheesy mounting bracket that is comes with.

Great Capacitor for the Price

Written By Travis, Fargo, ND on Friday, January 09, 2009

To those saying the capacitor helps reduce or even eliminate car lights from dimming, please consider doing the "Big 3" upgrade. A capacitor installed in that situation is merely a bandaid to the problem. Just Google the "big 3 upgrade" to find out which wires to replace in the car. Dimming lights is an electrical issue and is a visual aid to insufficient current being delivered by your alternator and/or battery.

That said, this capacitor is GREAT! I run about 1,000W RMS through 3 amplifiers to 6 speakers and a sub. There is a considerable difference to the bass reproduction and my sub became more responsive and MUCH more punchy. It's a great (and cheap) way to improve your car's sound after doing the big 3 upgrade.

I just bought this cap because i was tired of buying batteries or driving down the street with my lights dimming during a good song. I bought this and it seems like everythings is fine now. I think that a cap would make a big diff. in sound quality. But boy let me tell you it does.

But the cap somewhere where you can show it off. It has a bright leds on it that make your system look that much more better.

nice cap

i bought this cap to give more power to my kicker 1000.1 and a rockford fosgate 200.2 channel amp. it makes my system sound better and crisper.

I have a 1400 watt amp goin to 2 12 inch subs. bofore i put the capaciter in i had a major problem with every light in my car dimming. once i put the cap in, it solved the problem. my only complaint is that the top of the cap were u put the wires to is kind of flimsy. it hasn't hurt the performance of the cap, but i personally like things to be built solid.

Awesome backu!

Awesome! Made my JL Stealth 10" Sub Box for my 2008 Ford F-150 Limited punch hard and never dim any lights. Highly recommend it!

Nice cap

Written By osiris2600, Washington, DC on Saturday, January 19, 2008

I got this cap because I was tired of my lights dimming. Prior to getting this cap I've gone through 3 subs. Two jl 12w3's and one kicker. I had the feeling this had to do with how my shop set up my amps. I have two amps, jl 500/1 and 300/4 and they had the positive lead going directly to my 500/1 and they then combined another 4 gauge lead AT THE 500/1 terminal and then ran it to my 300/4. Let me say this again so that everyone understands! They cut both of the 4 gauge wires in half, twisted them together, and stuck it in the 500/1 terminal!!!

To make a long story short after my last sub blew I didn't bother getting a new one till I could get the cap and do a PROPER install. I bought the cap and installed it myself (without a sub) and my interior speakers were sounding BEAUTIFUL. I could instantly hear the difference. Then I bought a JL 12w7 and it's just insane. I've never heard such hard hitting clear sounding bass in my life.

Now the reason i gave it 4 stars instead of 5 is because at night my interior and head lights still dim a tad bit but definitely not nearly as much as they did without the cap. I'm not sure if "slight" dimming is normal at high volumes even with capacitors or maybe I should have bought one with a higher farad rating. I've heard that JL Audio amps actually pump out more then what they are rated at so I'm probably pumping more then 800 watts RMS. Even still, I thought 2 farads would have been enough.

In conclusion i'm very happy with this cap. A neat feature is that you can run two amps with this one cap and you won't have to buy a separate power distribution block which was very convenient for me.

LEDs too bright

Written By jeffery, Shreveport LA on Monday, June 18, 2007

Crutchfield Customer Review (What's this?)

I agree with the others, this cap is more than ample to throw power at my two subs (about 650 RMS).
My complaint is the LEDs are so bright they hinder my ability to see traffic in my rear view mirror (I have a Corvette). One other con is the plastic mounting brackets feel cheap. They seem to work well as designed, but I am not sure how long they will last before cracking.

Crutchfield Customer Review (What's this?)

I Gotta Say That This Capacitor is probably the biggest Difference in my System since it was installed. I know that sounds stupid since Head Units,Amps, Subs etc are everyones favorites...But I had no Clue that a Capacitor not only stopped the Power Drain on my Car but Could provide power to the point of "TRANSFORMING" Great sound into "AMAZING SOUND".

I Have AMPS (3), Polk Audio Components all around and 2 10" Subs. I realized I needed to upgrade my current 1.0 Farad Capacitor to something Larger. I Questioned the reccomendation of the Sales advisor thinking it was Overkill. Anyways, The Capacitor was a simple switch and when I finally tested my System to make sure I was getting enough Juice...I discovered "NONE" of my speakers had been getting the power they needed, MY SYSTEM SOUNDS LIKE IT COULD COMPETE IN A SOUND OFF.
The Tsunami is well built..Looks cool and the digital display only adds to the entire set up...I LOVE THE WARNING SIGNAL THE CAPACITOR GIVES WHEN YOU ARE TOO HIGH OR TOO LOW IN VOLTAGE......It is well Worth it....

TRUST ME...Do not cut corners when it comes to Capacitors. I could not believe how much my speakers were Starving and Tsunami Delivered. Even at Max Volume the Tsunami keeps a steady voltage Level. Compared to my last Copacitor, it is like the Tsunami is "Conscious" of what my System needs and it displays it for you to see...Very Impressive.....I HIGHLY RECCOMEND!!!

i have used 1 farad caps in the past with dissapointing results. this 2 farad cap works awesome .im running 1,000 watts total rms with a 150 amp main fuse.
this cap is the best i have had to date.
highly reccomended!!!!


Written By Julius, TN on Monday, December 11, 2006

No matter what people say, you absolutely need a cap. Even if your headlights dim a little like mine did and you THINK you dont need one...dont be fooled!

With a cap on your system your amp gets all the power it needs and will perform at its best all the time! That means louder bass, less stress on your alternator and lights, and overall improvement. Take the risk and dont get one, or do like i did and never regret having bought one!

Saves Headlights

Written By Greg, Houston, TX on Wednesday, November 08, 2006

Crutchfield Customer Review (What's this?)

I have learned that every system, even a fairly low powered one like mine, needs a cap. If your headlights are dimming at night, they are not gonna last long. The dimming causes inconsistent surges and will make the burn out quickly. The price on this site is the cheapest. At Circuit City this cap runs 189.99. I have had the cap in for approx. 3 weeks now and the power is very constant and no more dimming of the lights. It mounts very easily and looks clean with all of the LED's going. I even got hit the other day and the cap is still fine. I recommend this cap if you are running a, around 760-1300 watt amp. I also push Infinity products as well. Thanks Crutchfield for the great product and price.

best EVER

good cap does what it is supost to do and looks great doing it. using it with a kicker l5/ truck box combo and a rockford fosgate t3002 rated 300 watts but acrually puts out 583 rms :) great amp. and sub and cap. the only bad thing about the cap is the lcd voltage meater raddles hardcore but not a sound raddel just moves alittle bit but really fast but idk how its gona hold up... probly good. HOPFULLY FOR $150 BUT GREAT CAP OVERALL RECOMENDED!!!

Great Price - Fast Delivery - Cool Neon Lights/LEDs

Crutchfield Customer Review (What's this?)

I did alot of research trying to find a good looking capacitor in the 2 farad range that also performed well. Since this was my first install, I wanted it to have all of the right components to support what I was putting together.

Hifoncis Brutis 1605D 1600 Watts RMS (550W RMS @4ohm)
Kicker VS12L5 Combo Sub Box and Sub(S12L5 Solobaric)

Not once have I seen my headlights dim, hits so hard, sounds so beautiful. Looks cool too.

life saver

Written By quintin, Greenwood, sc on Tuesday, February 28, 2006

This cap is great, I have kicker 1200.1 and a sony 500 watt 4-channel amp connected to this cap and my headlights don't dim any more. It also improved the bass response from my 2 12" memphis M3s. It is worth every penny.

It also looks great!
