The AUX is an input! Gah... that puts a bit of a kibash on the external amp sub control with the empeg.

I'll keep reading the FAQ.

Can anyone else comment on the overheating issues? the fan info on the FAQ did mention that it was one reason that some people installed fans.

I guess I didn't list option 4

O4) Install Empeg with output going into input of a single-din receiver that has three output pairs to separately control amps. Therefore no amplifier in the same compartment as the EMPEG for heat. Separate amps would then be required.
