Also... if the two different side amps both have trigger inputs you could use that with a trigger that turns on/off by type to turn one amp on and the other off and then Y the output to both amps.

You would need a 12v PS and a normally closed reed relay to invert the trigger state of the Meridian for one amp.

Wire the Meridian trigger directly to one amps trigger input (amp A)and to the coil of the reed relay. Feed the 12v to the contact of the relay and to the amp you want ON when the Meridians trigger is off (amp B).

When the Meridian triggers is off amp A will have will have no 12v trigger and will be OFF. The reed relays coil will not be energized so it will feed 12v to AMP B turning it on.

When you change type and the Meridian trigger turns ON that will turn ON amp A. The Meridian trigger will also energize the reed relays coil opening that connection and removing the 12v from amp B turning it off.
