So this is how I currently have my audio set up in my 800ex. But you can never have too much sound and one thing that I need is bass. So I have decided to add two..yes two 8 inch subwoofers. If we had the luxury of more space under the console, I would add them there. But space is tight and I want to keep them out of the mud as much as possible. So I took some measurements this evening and decided to make an add on which will fit under the roof and use the existing roof mounts to anchor it down. I am also going to ditch the infinity bluetooth radio and add a second Kenwood bluetooth amp to the existing setup. If everything goes as plan..Ill be running two 8 inch subs, 2 6x9s, and 2 6.5 speakers. Not sure what I'll do with the tweeters...since I'll have two open channels...may keep them, or buy two new 3.5-4 inch speakers. While I was at the lumbar yard, I picked up an extra sheet of ply to make a custom cargo box as well.
