I need some assistance with an issue I'm having powering up my new equipment. I took all the OEM components out and replaced with an Alpine ILX-650 HU and Alpine amp in the back plus all new speakers. New speakers wires were run for all the speakers. I even ran new power, ACC wire, and remote turn on wire up to the front. I had the amp in the back working and now the light on the amp is off. I took the Violet/White wire for remote turn on the new amp and the white wire for ACC switched. This was from the large OEM amp plug in the back left side. Ran a 4 gauge power cable with a block to the right back side with where the + battery terminal was connected. Everything is grounded. I now have no power to the amp or the HU. What am I missing? Thanks.
