Super mini compact full range & class d amplifiers

TORO AUDIO Rage Mono Block amplifiers will draw large levels of current, so use the largest gauge power /
ground cable possible. Using too small of a power cable can result in unnecessary over-heating of the amplifier,
distortion at high volume levels and might even cause the thermal protection circuitry to shut-off the amplifier.
Remember, bigger wire and pure copper is better! For the best results we recommend a 100% Pure Copper
amplifier install kit available at your local TORO AUDIO dealer
Use rubber grommets when running cables through any metal or sharp plastic, to prevent accidental
shorting or shearing. Make sure the cables do not interfere with the normal operation of the vehicle
The audio signal cables (RCA Cables) should be kept far away from any potential sources of
electrical interference such as electronic vehicle management systems, relays, engine computers
wiring harnesses, fuel pumps etc.
This amplifier is designed to work within a 9 to 16 volt DC range. Before any wires are connected, the vehicles
electrical system should be checked for correct voltage supply with the help of a voltmeter.
First, check the voltage at the battery with the ignition in the OFF position. The voltmeter should read no less than
12V. If your vehicles electrical system is not up to these specifications, we recommend having it checked by an auto
electrician before any further installation. Once the vehicle is checked, make certain the correct cable gauge is used.
We recommend using as large a gauge cable as possible, use the Power Cable Selection Chart to calculate the
correct power wire size for your application. Remember Bigger is Better!
