I will be trying to install a simple amp and sub to our 09 Xb with the base sterio. Nothing upgraded. I have a line converter with volume control. I I was thinking of where I'm going to get the remote wire for the amp?

I have only installed stuff with a aftermarket head unit. Anyone know the recommended way to do this?


Also any tips on locations or routing for this and where I should tap into the rear speakers for the line converter.

This will be a small Birthday (surprise) present for my wife, and with our newborn I have not much extra time to be planing this. I have a few hrs scheduled for this.

thanks for your help guys/gals.
