Engine Compartment Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void your warranty. Trunk Mounting Mounting the amplifier vertically will provide adequate cooling of the amplifier. If you will be mounting it to an existing panel, be sure it’s not prone to excessive vibration (such as mounting to the back of a subwoofer enclosure). - Page 8 Trim the power cable within 18 inches (45.7mm) of the positive battery post and splice in a in-line fuse holder. DO NOT install the fuse at this time. Strip 1/2 inch (12.7mm) from the battery end of the power cable and crimp a large ring terminal to the cable.

This allows you to control the level by attenu- ating the amplitude or increasing (up to the maximum set-point) of the amplifier’s input gain control. This control does not add additional bass boost, it simply allows you to control the level to suit your tastes.
