I have an 03 sierra with the Bose in dash 6 disc and 6 speakers.

I am pretty sure there is a sub hidden in the center console. Does anyone know for sure where its hidden and if my truck even has one?

If so is there a new sub I can replace it with?

If I want to replace the front component (woofer/tweeter) speakers are there any I can use that DONT require any wiring and can just plug in?
