Do your headlights flicker when the bass hits hard? Does your bass start out strong, and then fade into mush after a minute or two? Car batteries are slow to deliver the kind of power your amps need to give you tight, powerful bass hits. Lightning Audio capacitors eliminate that problem by storing reserve power and then delivering it when your amps need it most. That's why you see external capacitors in just about every stereo competition vehicle and you don't see dimmed headlights.
Lightning Audio's Strike Caps act as a buffer zone between your amp and your battery, getting the juice to your bass for maximum performance. The LSD10-03 1-farad capacitor can be used with amplifiers producing up to 1,000 watts RMS. The digital voltage readout shows your exact voltage to the decimal point. Visual and audible warnings tell you if the cap has been wired backwards.
Note: The capacitor is installed on the power cable that connects the amplifier to your vehicle's battery. You will need a short length of ground cable and crimp-on connectors (not included) to install the capacitor. The ground cable is used to connect the capacitor's negative terminal to the chassis of your vehicle.Details:
- 1-farad cap for systems of up to 1,000 watts RMS
- digital voltage readout
- 16-volt maximum (20-volt surge)
- 3-1/16" diameter x 9-5/8"H
- 1-year warranty

Crutchfield Customer Review (What's this?)
i figured i would need a capacitor since my amp is pushing my subs at 750 watts RMS, my headlights were dimming and my amp was having some clipping problems, even though it was giving the subs wattage rated over their maximum. as soon as i installed this cap, no more clipping or dimming lights and the bass actually seems to hit harder. great product

Overview: The overall response of your audio system will be enhanced with the use of capacitors due to their ability to quickly supply a large amount of current to your amplifier's power supply during high current demand (low bass). This makes the Lightning Cap a logical addition to your system due to the fact that automotive electrical systems 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. A one Farad capacitor is recommended for each 1000 watts of amplifier power, although you can never have too much capacitance for any system.
LED Digital Display (With Auto Turn-On): The capacitor's monitor top features a blue digital LED display. The current DC voltage readout appears on the 1" x 1/2" display. The display senses voltage fluctuations during normal operation and turns itself on. After 5 minutes of non-use (no fluctuation), the display automatically reverts to sleep mode.
Equivalent Series Resistance (ESR): The Lightning cap is able to deliver its power quickly because its super low ESR. Each capacitor has up to 18 ultra-sonically-cold welded tabs that connect the foil winding to the terminals at the top of the capacitor with almost no resistance.
High Gain Foil: Lightning capacitors use a high-gain foil. High-gain foil is created by passing the foil through several high-current (10,000 amp) chemical baths that "etch" the foil and create surface area. This allows for more capacitors in a smaller area.
Through-Post Design: The monitoring circuit is wired in parallel with the capacitor, not adding any resistance or inductance which could prevent the cap from doing its job.
Reverse Voltage Warning: A buzzer will sound if the capacitor is connected backwards.
Mounting Brackets: The Lightning cap is equipped with two translucent plastic mounting brackets. The brackets allow the cap to be mounted in virtually any position on a vertical wall or a horizontal surface.
Installation: In addition to the wires and connectors for your amp installation, you will need a short length of ground wire and 2 pairs of ring terminal connectors with 5/16" holes (1 pair for the power wires and 1 pair for the ground wire) to properly install the capacitor. One length of power wire connects from your battery to the capacitor's positive terminal, while a separate length of power wire connects from the capacitor's positive terminal to your amplifier. (It is recommended that the capacitor be wired no less than 18" from the amplifier.) The ground wire connects from the capacitor's negative terminal to the chassis of the vehicle.
- Size: 1 Farad
- VDC: 16V, 20V surge
- ESR: < 0.00198 ohm at 120Hz 25c
- Terminals: 1/4"-28 thread
Packaging Correction: Some of the packaging may incorrectly indicate that this capacitor has a distribution top. It has a standard top with a single positive and a single negative terminal.
