If you do a little shopping around .. you may find the items I chose at a better price.. But it all is pretty decent and will last you until you want to upgrade at a later time. Should sound pretty good. A pair of subs would be Ideal. That one 10" sub will fill that cabin pretty nicely, and those component speakers will get loud and clean if you set the gains and ect on HU and amp properly. That Tahoe ist hard to install a system in if you want to try.It is actually one of the best and easiest vehicles to learn from to be honest
