ELECTRICAL INSTALLATION
PYRAMID SERIES
1. 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
#8 wire.
2. Connect the remote terminal to the remote output of the head unit
using #14 wire.
3. Connect an empty fuse holder within 300mm (12") of the battery and
run a #8 or larger high quality cable from this fuse to the amplifier
location.
4. Make sure there is no fuse in the fuse holder. Then make the connec-
tion to the "BATT" connection on the amplifier.
5. If multiple amplifiers are being used, either run separate cables. (each
with its own fuse at the battery) or a #0 or #2 cable from the fuse holder
at the battery to a distribution block at or near the amplifier's location.
6. Connect all line inputs and outputs using high-quality RCA-RCA cables.
7. Insert fuse(s) at the battery fuse holder(s).
8. Recheck all connections before powering up.
9. Set all level controls to their least sensitive positions and set all crossover
controls, switches, etc. to the desired frequency or position.
10. 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
control for maximum sound pressure.
11. When bridging the amplifiers be sure to change the stereo/mono switch
knob to the in position for the appropriate channels to bridge.
12. Further fine turning of the various controls may be necessary to obtain
the desired results.
PLEASE NOTE:
The gain control of any car audio amplifier should not be mistaken for a
volume control. It is a sophisticated device to match the output level of
your source unit to the input level of the amplifier. Do not adjust the level to
maximum unless your input level requires it. Not following this instruction
will result in an input overload to the amplifier and high levels of distorted
musical reproduction.
