Head unit help

[cougarkidd]

I just installed an aftermarket head unit in my 2002 tahoe with the bose audio system. It replaced the out-dated aftermarket system the tahoe had when I got it. They only wire I didn't replace was the one to the aftermarket xm unit. I am not getting any sound through my speakers now. Does anyone have any ideas?

make sure you have a remote hooked up from your bose system to your new head unit
