So my ride crapped out and I been looking at bigger SUVs. I actually had the chance to check out the box style and rounded (not the newest) tahoes and the cargo areas look very small to me. My folks own a 99 Expeditions and thats not to big either. I want daily driver with 2nd row in. I believe i measured 20 cubes in the expedition with the 2nd row in from top to bottom to back. The tahoes may have a little more. I planned on 4 "15s in a 4th wall, but I'll settle for a flat. I gotta include amp rack, displacement, batteries and all that good stuff. Honestly, my 98 explorer looks like it had almost that same amount of cargo. How are people getting multiple 15s and 18s in these trucks without gutting them? I love audio but I thought about scrapping that plan and buying a fox body or 94-98 mustang gt and making it a monster.
