To bypass the Bose Amp in a 2003 Chevy Tahoe in 15 minutes,
Remove the black plastic center console insert with door attached. (Phillips head screws. use a small screwdriver to force the console liner forward so it will move free of the back console panel with the cig lighter etc.)
Remove the back console panel if you want more room to work, strip wires, etc. (4 phillips head screws on back, reveled by opening cup holder, 2 screws on top, revealed after console insert removal.
