First off, The amp remote wire from the empeg is to turn your amplifier on, not to tell the empeg when to turn on. Discconect it from the "switched" power. If you're using another head unit, just tape off the amp remote wire and don't worry about it.

Seccondly, it sounds like you've still got your constant and switched power wires mixed up. Try switching them around and see what happens, or put a meter on them and observe what's going on.

Thirdly, spend some time familiarizing yourself with the FAQ. It's great reading, and it gets better the seccond and third time through.
