I just bought a new Alpine head unit for my supra and i made all the right connections on the wiring harness, but when i plug it in, it doesn't even come on. I was thinking that the stock amp could possibly be blown, since my IH1 and IH2 connections still work. Any suggestions?

You shouldnt even be using the factory amp if you installed a new HU, and if you did use a integration wiring kit, check the remote turn on lead
