My friend and I were installing a subwoofer and ranned into a problem at the very end. The amplifire is a 2Ch 900W amp and it's a LEGACY. The deck is the SONY CDX-MP40 and he wired the wireharness and everything the way it should be. Once the power was on and tried out the sub . . . nothing. The power on the amp was still OFF. We tested the power with a voltage meter and it showed we had power. We messed around with it for a long while and at one point he got the "Protect" light from the AMP to turn on. That was where we ended up and gave up. If any of you know what to do, please, please let me know. If you have any wiring schematics for the cdx-mp40, please let me know. Thanks so much. We worked on it from 5:30 pm to 1:00 am.
