Don, I replaced mine with the Bose cubes. I did have to use a file to enlarge the holes just a tad. I also added two above the rear window in our 3400 and gave the OEM DVD system to charity and replaced it with a Yamaha 7.1 receiver. Left the two speakers over the main slide. Also replaced TV with a 32" LCD HDTV. Sounds great and great picture.
