Hi, and welcome to the site! Glad to have you here! I seen where you posted about the 2002 Avalanche stereo replacement. I also seen you are a car audio installer. That is what this site is all about, helping members, and you fit right in! Thanks for your input, and I look forward to talking to you in the future!
