Um, yeah, you've wired it wrong.

Blue wire from empeg needs to connect to the blue wire on your amplifier in the boot. You might have to run this wire yourself, rather than using a wire on the harness.

Blue wire from tuner module needs to connect to the antenna power amplifier or antenna raise/lower motor on your car's wiring harness.

Orange wire from empeg needs to connect to the ignition-switched power from you car's harness.

Yellow wire from empeg needs to connect to constant power from your car's harness.

The reason you're havnig trouble is becaue you did the wrong things with the orange and blue wires.
