I bought my wife a new Alpine cd player for christmas. Got the XM radio tuner, install kit, harness, adapter, everything needed to install it in her 2002 Tahoe(non-bose) I have been installing my own stuff for years. Multiple subs, amps, x-overs, you name it i have probably done it. I took the time last night to solder all connectors and used heat shrink to connect the radio harness to the install kit harness. Got everything ready last night, for a quick install this morning while she is still asleep. I am trying to suprise her with it. Wanted her to hop in the truck to go to work and see the new stuff and be like "wow". So, i get up this morning, hook it all up, all good, shes still asleep, and what do ya know, no freaking sound. Everything lights up and works, just no sound at all, radio or cd. I triple checked everything. I must have gotten a screwed up radio. Now I have to go exchange the damn thing

 

just a couple of thoughts- does the Alpine have an option to turn off the internal amp to run an external? If so, this may be on. Also, if the deck has a wire for an auto-mute for a cell phone, make sure this wire is taped off and not exposed as well. Hope this helps somewhat!

 

which model number is it?
