Capacitor Specifications

Capacitance (farads)
Capacitors are rated in farads, and at times microfarads or millionths of a farad. The more farads the capacitor is rated at, the more electrical charge (and wattage) the capacitor will hold. Capacitance is defined as the property of storing an electrical charge between two separate conductors.
30 farads
LCD Meter Display
Displays the current voltage and/or other specification on an LCD readout.
Yes
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.
4 AWG
Built-In Distribution Block
A built-in distribution block simply means that the item includes a distribution block. The built-in distribution block will split the single power input into a multiple power output.
No

Great way to power your system!

August 8, 2013

I bought this because I run two batteries in the rear of my vehicle and wanted to lessen the stress on my batteries. Plus I run a High watt comp. amp with a single 15, so I need the extra juice for long bass hits. Over all great piece of hardware, just make sure your car or truck can handle the extra stress on its alternator.

off brand but still good product

September 7, 2012

Yes, it is an off brand product. I've had mine for 6 months and had no problems or issues with it. The light bar seems to do nothing other then flicker depending on slight voltage variation it goes wild. 30 farads in the size of two standard single cylinder capacitors? Yes. Works just as expected. You may be better off with a secondary or third or fourth battery, but unless you have 14.7-15 volt batteries then your voltage will drop to 12 then stay there. This will get you up to a stable 14.7 and stay there quite well, even if you run a 3800+ Watt rms amp Running with: Lanzar Vbp 281 4200wpeak about 3850 rms if I remember correctly

Excellent merchandise

August 18, 2011

Excellent merchandise, I had the Boss CAP30 for a little bit now. It works great. When I first installed the Boss CAP30, I could tell a major difference in my system. The bass sounded different, and I didn't have a loss of power. Plus I purchased it at a great price. I love the Boss CAP30 and will be getting another one.

great product

April 5, 2010

this product works great. i have full 2ga wire run to it then to a db block and then to three 2000 watt amps which power 3 spl 12s and it works great. it barely drops down to 11 volts when the bass hits really hard even with all that stuff. I love how the lights on it pulses with the music. I don't like how the screw holes where you can mount it are made of plastic cause they will break easy if you mount it too tight.
