installation
1. Disconnect the battery ground cable. Reconnect the ground cable only after the installation is
complete and the wiring has been checked to make sure that there are no problems. If your
radio features a code type security system, be sure you know the code before disconnecting
the battery!
2. Run a minimum AWG #8 power wire directly from the battery to the PowerPlate™ mounting
location. Install a fuseholder at the battery end of this cable either within 18" of the battery
or before the wire runs through any metal partitions. Do not install the fuse at this time.
3. Attach a minimum AWG #8 ground wire to a solid chassis ground point near the mounting
location. Keep this wire as short as possible. Scrape all paint and primer off of the sheet
metal at the ground point to ensure a good electrical connection. Attach the wire to the
ground point with a nut, bolt and star washer.
4. Run the signal leads and remote turn-on leads from the head unit to the PowerPlate™
location. If using an internally powered radio or factory radio refer to the "signal sources"
section for the proper wiring connections.
5. Install the speakers and run each of the speaker leads to the PowerPlate™ location. Connect
the speaker, remote, and power wires to the appropriate terminals on the plug-in terminal
blocks. Refer to the "controls and connections" or "system planning" sections for
information on the proper connections. The speaker terminal blocks install with the set
screws facing up and power terminal block installs with the set screws facing down.
6. Preset the 2/4 channel selector switch, crossover and channel mode switches, and crossover
frequency switches to the desired positions. Refer to the "controls and connections" section
for more information.
7. Adjust all amplifier input level controls to the 1/4 position.
8. Mount the amplifier into position and plug in the power and speaker terminals. Attach the
input signal cables.
9. Reattach the battery ground cable.
10. Double check your switch and control settings. Install an 60 amp fuse in the fuseholder you
have installed near the battery.
11. Turn on the signal source at a low volume level. Using the balance and fader controls, check to
see that each channel is connected to the proper speakers. Make sure that the proper
frequency range is being sent to each speaker if you are using the crossover features built
into your PowerPlate™.
12. Adjust the input sensitivity and crossover frequencies as described in the "tuning" section.
13. Read the rest of this manual to get maximum enjoyment from your system.

power connections
• Use AWG #8 or larger power and ground cable.
• Install 60 amp fuse in the power wire within 18" of the battery.
• Keep the ground wire to a minimum length and attach solidly to a clean metal part of the
vehicle. The addition of a .5 Farad to 1 Farad power supply capacitor, mounted as close as
possible to the PowerPlate™, may improve performance in some systems.
