1 I NTRODUCTION Congratulations on your purchase of a QUANTUM AUDIO state-of-the-art power amplifier. Your selection of a QUANTUM AUDIO product indicates a true appreciation of fine musical reproduction.
S AFETY PRECAUTIONS Fuse amplifiers power wire at the battery. Be sure to fuse the power wire within 12” of the car's battery. This will protect the car's battery in case of a short circuit between the power amplifier and battery.
F EATURES AND BENEFITS DC Offset Protection This circuit protects the output of the amplifier against DC voltage. If for some reason DC voltage is detected at the output stage, the amplifier will shut down protecting the speakers from direct current.
Line Out One set of full range line outputs have been provided for convenient connection to additional amplifiers in the system. Power Fusing This protects the amplifier against short circuits and excessive current. Remote Turn-on Automatically turns amplifier on when connected to the head unit's remote output.
M OUNTING LOCATION Before you start the installation, it will be necessary to find a mounting location for the amplifier. Find a location in which the amplifier will receive adequate ventilation in order to dissipate the heat it develops during operation.
P OWER CONNECTIONS IMPORT ANT! Before making any connections, disconnect the car’s battery until the installation is completed to avoid possible damage to the electrical system.

5v .2v . The SOLAR series amplifiers are equipped with a built-in variable crossover network allowing you to select the crossover type (i.e. Low-Pass or High-Pass) and the desired crossover point. For example if you wish to drive a pair of subwoofers, you can select the “Low Pass” setting on the amplifier to filter out high frequencies.
T ROUBLE SHOOTING THE SYSTEM We have put together this trouble-shooting guide if you experience problems after installing the amplifier. Please keep in mind that the majority of problems incurred are caused by improper installation and not the equipment itself.
