Testing
Before finishing the installation, perform the following tests to make sure the
wiring is correct and everything is operating properly.
Reconnect Battery
When wiring is complete, reconnect the battery negative terminal.
Test Power Wiring
Turn on the receiver, but do not turn up the volume. The amplifier power light
should come on. If not, check the REM and +12V (B+) wires. Turn up the
receiver volume slightly. All speakers should operate. If not, check wiring
connections at amplifier and speakers.
Test Speaker Connections
These tests make sure the speakers are connected properly. If speakers don’t
play at all, one (or both) speaker wires may be disconnected.
Remote Input Level Control
The Power 900 and 1050 come equipped with a Remote Input Level Control.
The Remote Input Level Control allows the input level to be adjusted from an
alternate location. It can be mounted under-dash or in-dash. When the
amplifier is used to drive subwoofers and the low pass crossover is activated,
the Remote Input Level Control can be used as a “remote bass level control”.
This enables you to control the bass level independent from the rest of the
system. This is convenient for system tuning and/or when playing many
different types of music.
The Remote Input Level Control uses a 6-pin modular cable for connectivity.
Simply plug the 6-pin modular cable into the amplifier and then into the
Remote Input Level Control to activate the circuit.
