Stiffening Capacitor Wiring

There is often a lot of confusion on how to wire a car audio capacitor a k a.
Stiffening capacitor wiring. Scosche 500k micro farad capacitor wiring diagram a. Low frequency causes the most power draw in an amplifier so automotive subwoofer amplifiers are the main application for stiffening capacitors. A resistor or wired light bulb usually is included in the package. Stiffening capacitors can help your automotive amplifier deliver more output on peak bass transients.
A positive and a negative. The same bulb or resistor wired differently also gets used to charge up the cap safely. A stiffening or power capacitor is a great addition to any stereo system. Sometimes however the installation instructions for these devices tend to be lacking in description and can cause a bit of confusion.
The rxc2d assures undistorted performance from your high powered car amplifier system. Wiring the bulb or resister across the cap s terminals allows the capacitor to discharge slowly and safely. There are two terminals on a car audio capacitor. Car audio capacitor installation.
The rockville rxc2d is a 2 farad 12 volt stiffening capacitor which features a lucite encapsulated led digital voltage meter display and logic control circuitry. A new cap comes completely discharged so it s safe. The negative terminal is connected to ground. The rule of thumb is to put in 1 farad of capacitance for every 1 watts rms wiring the bulb or resister across the cap s terminals allows the capacitor to.
Let s straighten things out and make pre charging your capacitor as painless as possible.
