TO AUDIO OUTPUTS OF HEAD UNIT OR

SIGNAL PROCESSOR WITH STEREO

OUTPUTS

If your head unit has two pairs of RCA output jacks, input Front Left and Front Right to channels 1 and 2. Then attach the rear pre-outs to channels 3 and 4. The pre-amp circuitry

will not mix any signals thereby preserving full left to right balance and font to rear fader control.

Should your head unit have an additional subwoofer RCA output it would need to be attached to a separate subwoofer amplier.

When conguring a four channel amplier to a three channel system, you can use an RCA “Y” adaptor to send the subwoofer pre amp 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.
