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. Should your head unit have an additional subwoofer RCA output, that typically needs to be attached to
a separate subwoofer amplier.
When conguring a 4 channel amplier 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.
