I was pretty disappointed with the Mac system until I finished the subwoofer relocation project. I have now flipped 180 degrees and really like it. Thanks to all for the idea. I posted pictures in the photo album to show how I did it. I used the inside dimensions of the wood box but substituted one quarter inch aluminum diamond plate. My speaker mounts with spacers and the child restraint bolt holes so the pockets are un-touched and useable. My AMP bracket mounts with the holes that had the pocket posts behind the driver’s seat and I made spacers to hold the pocket straps. The Amp tabs did not get bent out and the pockets still functions as stock. The sound is terrific. The bass is now much stronger and is not blasting in my ear. This is a great fix for the MAC. If you have a Mac, you should definitely move the subwoofer.:biggrin
