You could go to Walmart and get a big umbrella that would do the trick for under $50.00 and you could use it at the beach as an added bonus.

@stanger_missle Here's the link for the head unit I put in. This one has a 45 watt amp build into the system. It even has capability to hook up a powerless sub to the unit without needing an external amp. Your link didn't work when I clicked on it BTW. Cost about $250. Mind you, if you do opt for one of these powered head units, you will need to run a dedicated power wire to the battery from the unit. I did not read the fine print on that, and had to order a wiring kit separately. When I looked around the rear doors, I did not see anything where the speakers should be. I can't guarantee buying a set of speakers, wire, and mounting hardware will set you up for an easy install. I don't plan on expanding into the rear of the van with speakers, I haul stuff too often to do that. What I would recommend for better sound is a few things: Upgraded speakers, and either an amp and a head unit, or the combo of both like we mentioned will help significantly. I am content with my Rockford 3-way speakers and my powered head unit. If you want to stretch it further, I personally feel like wiring your own tweeters in the a-pillars will be an easier job than putting more in the back of the van. Road noise has to be battled with insulation. I have not gotten to that point in the build yet, but as you can see yourself, there is a ton of opportunity to insulate. Let me know if you have any other questions!

@stanger_missle - Don't think you're overthinking this at all. You're just exploring the what ifs, which is cool. I too have a cargo van with only two speakers in the front doors. Below is a pic of the slider doors speaker mounts you're referring to. Your concerns about road noise are valid. I personally wouldn't bother mounting speakers there. I think that mounting point would be good if you had passengers in this area but it would be a waste otherwise. If you want music for the cab area, then that's where I'd add or upgrade speakers for better sound. If I spent more time in the van I would consider an audio upgrade. Good luck!
