Stereo system for 2001 Yukon Denali?

yes his car does have a factory Bose speaker system throughout the vehicle, I think however you should go with Infinity Kappa speakers all the way around then 2 kicker solo-baric 15's in a nice bandpass ported box. with a good kicker amp maybe 1600 watts Max which is usually at 2 ohm's you will run about 1300 watts RMS to the subs. You should in that vehicle hit around 145.9db's. Also if I were you I would build a small platform in the back of the vehicle to angle the subs to where the reverberations hit the windshield and bounce back to you. You will then really hit around 150db's or close to it.
