If your headlights dim every time your subs deliver a big bass hit, you could use a Tsunami power capacitor to stabilize the power between your amps and your car's electrical system. Tsunami makes high-power, competition-level capacitors that store up power, then deliver it to your amps when they need it most, during moments of peak demand. Your amps will maintain maximum performance even under extreme conditions.

Tsumani's HCAP-5 5-farad capacitor is suitable for systems totalling up to 2,500 watts RMS. This hybrid capacitor uses the latest battery technology to store more energy per cubic inch than a standard cap, and this reserve power gets delivered instantly to your amps whenever they need it. An LCD readout shows how much voltage is pumping through your system, while the amp-style chassis makes this cap look right at home with almost any amplifier setup.

Product Highlights:

  • 5-farad hybrid capacitor
  • blue LCD voltage meter
  • silver anodized amp-style housing
  • hidden connection set screws for neat installation
  • red flashing LED low/high-voltage warning
  • 1/0- and 4-gauge positive and negative wiring terminals
  • 10-1/4"W x 2-1/4"H x 6-9/16"D
  • warranty: 1 year
  • Our 60-day money-back guarantee

Crutchfield Customer Review (What's this?)

I bought this capacitor because tsunami has a great name behind it and I have always been satisfied with their products in the past. I am currently running two Alpine Mrp-M1000 amps off of it, and also one Alpine PDX 4.100. It has no problem and my lights dont dim at all!!! The MRP amps are powering two ten inch Alpine Type X subs in my 2002 vw gti! They slam really hard. I would recommend this capacitor who anyone who wants to go big!

Product Research


Overview: The overall response of your car 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 digital hybrid 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.

Note: One Farad of capacitance is recommended for each 500 watts of amplifier power, but you can never have too much capacitance for any system.

Digital Hybrid Capacitor: The Tsunami HCAP-5 is a 5.0 Farad high-performance digital hybrid capacitor with digital volt meter. It provides two 1/0 or 4-gauge power/ground inputs and four 1/0 or 4-gauge power/ground outputs for installing a multi-amplifier system (up to two amps), totaling up to 5,000 watts RMS.

Styled Casing: The Tsunami HCAP-5 digital hybrid capacitor features an extruded aluminum case with chrome plastic accents. It also features a hinged cover to hide the capacitor's terminal connections.

Digital Volt Meter: The Tsunami HCAP-5 features a blue digital LCD volt meter. Hi/Lo voltage is indicated by flashing red LED's.

Note: The Tsunami HCAP-5 has an operating working voltage of 20-volts (24-volt surge).

High-Current Terminal Blocks: The Tsunami digital hybrid capacitor features 1/0-gauge nickel-plated high-current terminal blocks with 4-gauge reducers. The HCAP-5 features one positive input, one negative input, 2 positive outputs, and 2 negative outputs.
