I have searched and I thought I'd be able to find a thread on this, but I missed it I guess.

I am replacing my HU and I need to power the HK amp. I know what pins are what, but what I need help with is actually finding the switched power wire in the dash that I can hook up to the amp (Pin 10) i think it is.

From the info I have read it seems like the HU doesn't put out exactly a hot/ground for the amp?

Can anyone help, it's driving my crazy.

Thanks!

The amp power should be going to the amp from the fuse box..the remote wire to turn on the amp is behind the radio and is probably white

If you are using the AI BWH-470 wire harness adapter, all you need to do is simply wire your remote turn-on wire from your new head unit to the blue wire on the BWH-470 harness. This is the remote turn-on wire that will power on your factory amplifier.
