Be sure to mount the amp in such a manner as to allow reasonable airflow over the cooling fins. Mark the location for the mounting screw holes by positioning the amp where you wish to install it and use a scribe (or one of the mounting screws) inserted in each of the mounting holes to mark the mounting surface. If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. Before attempting to drill the mounting holes, take note of any wires, lines or other devices i

wiring tips fuses Connect the power ground terminal to the nearest point on the chassis of the car. Keep this ground wire less than one meter (39") in length. Use 4 gauge wire. Connect the remote terminal to the remote output of the head unit using 14 gauge. Connect an empty fuse holder within 300mm (12") of the battery and 4 gauge or larger high quality cable from this fuse to the amplifier location. Make sure there is no fuse in this fuse holder. Then make the connection to the "BATT" connecti

Couple the RCA input with the car stereo or equalizer outputs using RCA type connector cables. 5.

If the mounting surface is carpeted, measure the hole centers and mark with a felt tip pen. Before attempting to drill the mounting holes, take note of any wires, lines or other devices in your vehicle which may be located behind the mounting surface! Then drill pilot holes in the mounting surface for the mounting screws and insert them. Tighten the screws securely. wiring tips When making electrical connections to your amplifier, please observe the following: Use at least 8 gauge wire for power

.PQA power amplifiers are designed to fit standard 19 racks, with a 2U height and 17 depth. We recommend the use of rear rack supports, especially if the rack is to be mobile. Use shake proof washers or thread lock adhesive to prevent mounting bolts becoming loose in transit. .Ensure that the AC power supply is correct for your amplifier. The required AC supply is stated on the rear panel next to the AC power input. . Ensure that you use the correct type of mains lead for your equipment and coun
