Install any combination of speakers
independently on all 4 channels being
careful not to load any single channel
below 2 ohm stereo. For typical 6” x 9”
or 6.5” or component speaker installs,
set the Crossover Mode Switch to Full
Range.

If your head unit has 2 pairs of RCA output
jacks, input Front Left and Front Right in to
Channels 1 and 2. Then attach radio output
Rear Left and Rear Right to Channels 3
and 4. Set the Input Mode Switch to 4Ch
position. The pre amp circuitry will not mix
any signals thereby preserving full Left
to Right Balance and Front to Rear fader
control.
Should your head unit have an additional
subwoofer RCA output, that typically needs
to be attached to a separate subwoofer
amplier.
When conguring a 4 channel amplier to
a 3 channel system, you can use an RCA
Y adaptor to send the subwoofer preamp
signal to channels 3 and 4 and bridge those
channels to the subwoofer. Use Y adaptors
to mix channels 1 and 3 and input them
into RCA Channel 1, then mix channels 2
and 4 and input them into RCA channel 2.
The result will be preserved Left and Right
balance with constant subwoofer output.
