Smooths out the bass

T-Spec's 1.5-farad capacitor will help your vehicle's charging system keep up with your high-powered sound setup. When the power of the bass threatens to overwhelm the electrical system, this cap quickly provides a jolt of stored power to keep the beat pounding and your headlights from dimming. And it recharges quickly, so it's always ready for the next hit.

Displays the voltage

A bright, digital meter displays your system's voltage, so you can monitor how things are going and avoid overtaxing your vehicle's charging system. We recommend this 1.5-farad cap for any sub amplifier delivering up to 1,500 watts RMS. Warranty: 1 year.

Crutchfield Customer Review (What's this?)

The product works great. LED voltage reading is a nice feature. This unit doesn't have a 3rd terminal, which was something mentioned in another review (not sure if it was on here). It's a 2 terminal cap.

Pros: Does what it should. Includes enough hardware.

Cons: None yet.

Awesome

Written By mfolta, Laddonia, MO on Monday, December 16, 2013

Crutchfield Customer Review (What's this?)

I'm certain the capacitor will do the job that it is intended for, just for my application I do not like it.

Pros: 1.5 Farad should prevent the head lights from dimming.

Cons: No protective cover for the power terminals-must be mounted with decent clearance to prevent shorts.

Helps out

Written By Anonymous, Ms on Monday, August 19, 2013

Crutchfield Customer Review (What's this?)

Does what it says. Helps out with headlights dimming and keeps voltage up about 1.5 volts more than without.

Pros: Does what it claims

Cons: Big and bulky. Needs to be smaller.

Product Research

Features

Overview: This T-Spec v6-series digital capacitor will improve the performance of your car's electrical system by acting as a buffer between the alternator and your amplifier. Stored energy from your car's electrical system is held in the cap and quickly released to the amplifier when needed. High current demand occurs when the music you are playing contains a loud, transient, deep bass signal.

Capacitance: This T-Spec v6-series digital capacitor has a rating of 1.5 farads. While you can never have too much capacitance, it is recommended that you use a capacitor with a minimum of 1 Farad for each 1000 watts of amplifier power.

Terminals: The capacitor features an impact-resistant polycarbonate cover with two terminals on the top that can be tightened/loosened with the supplied 5mm Allen wrench. You should use power and ground cables that are equipped with ring terminals with 1/4" diameter or larger holes.

Voltage Meter: This capacitor has a digital voltage meter on the top to help you monitor your electrical system's performance.

Reverse Polarity Protection: If the capacitor is wired incorrectly, you can damage your equipment or electrical system. To prevent this, the capacitor has an internal relay system which disables the capacitor and triggers a buzzer to sound.

Resistor Bulb: The capacitor comes with a 1/2-watt, 1000 ohm resistor bulb which is used when initially charging the capacitor, and to discharge the capacitor when removing it from the system. You should keep the resistor bulb in a safe storage location when not in use.

Mounting System: The cap comes with a simple mounting system that lets you mount the unit vertically or horizontally, using the four supplied self-tapping screws.
