Make sure there is sufficient air flow around the intended mounting location
Bolt the amplifier to the mounting surface.
w iConnectr i n theg powert i pgrounds	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.		7
Make sure there is no fuse in this fuse holder. Then make the connection to the "BATT" connection on the amplifier.

If multiple amplifiers are being used, use cables (each with its own fuse at the battery) or a *0 or a *2 cable from the fuse holder at the battery to a distribution block at or near the amplifier's location.

fuConnects e s all line inputs and outputs using high-quality RCA-RCA cables. Insert fuse(s) at the battery fuse holder(s)

Recheck all connections before powering up.

Set all level controls to their least sensitive positions and set all crossover controls, switches, etc., To the desired frequency or position.

Once the system is powered up, set the volume control on the head unit to about the 2 o'clock position, and then set all the amplifiers' level controls for maximum output level. Further fine tuning of the various controls may be necessary to obtain the desired results.
