[QUOTE="audio_guy, post: 7555099, member: 637945"] A) Fusing is at most times now a personal preferance. Some people fuse and some dont. I dont measure exactly how long the wire is between my fuses but I would guess maybe 10" from the battery and about 6" from my amp in the rear. Fusing both places is an extra measure just incase something happens to pierce the insulation, it will blow both fuses and not damage my amp. B) Most of the metal "sheeting" you see is a form of a CLD tile. It is a reasonance barrier. It is to prevent pannels, such as door skins, to keep from reasonating. It in-sense is a stick on mass substrate to add weight to the panel. You use it to keep the horrible sound of sheet metal flapping down. C) In some cases mounting the amp directly to the box is a bad idea. Some amps that use spring clips will vibrate loose and cause the amp to go into protect. Common with the older Sundown 3000's. If you absolutely have to mount the amp to the box and have no other place to put it, I normally put some form of a rubber spacer, i.e.; small grommet or a solid piece of rubber drilled and rouded, and put that between the amp and the box on the mounting feet.
