What models of Tahoe or build packages come with a sub woofer in the center console?

 

I figured it out at least in regard to my 07 LT. It did not have a sub woofer in the console. I did however upgrade the speakers - Infinity Reference series component in the front and Infinity Reference 2-way in the rear doors with a Alpine 4x50 amp. Looking to possibly invest in a JL Audio Stealth sub & amp at a later date. Still breaking in the Infinity speakers which were installed yesterday and playing with the gain settings.
