To reduce house battery consumption on overnight trips can I by pass the amp when I want to?

My 4 speaker system is all on the "forward" speakers so the rear speaker function and wires of the head are not used. There is a second pair of RCA jacks and wire going to the amp, not hooked up.

What if I:

Plugged the RCA's into the rear output of the head.

Wire the other end of the RCS's into the current speaker out (front) side of the amp.

Put an on/off switch on the head to amp wire.

Turn off amp switch and put radio on rear fade.

Will that work?

Your speakers are still connected to your amplifier. If you turn off the amp the head has no connections to the speakers. Agree?

Sorry, I am not very smart about amps.

The speakers in addition to being wired through the amp would be wired direct on the out side of the amp through the rear out RCA's which are not currently used.

An amp on low volume is not really taking all that much power...I'd just fade one set of speakers to run and keep it soft....lower the bass too......or bypass the system altogether and get a cheap boombox and 12V power cord to cig lighter...

The speakers are connected to the amplifier with speaker cables. The amplifier connects to the head unit with RCA cables. That isn't going to work, they aren't the same thing.

this could be done with 8 SPDT relays or an 8 pole switch, but it would get messy and wouldn't be worth it. Do as Glen says and just keep the volume down.
