i was able to take the spoiler completely off, remove the factory sound deadening material, lined the whole spoiler that made contact with weather stripping. also took the brake light out of the spoiler and lined that also. the brake light was a huge part of the rattle. however, today i found out that my so-called 1000 watt amp was no where close to pushin that much. there are 2 25 amp fuses in the amp and that is a tell-tale sign i guess. so now i'm lookin for a true 1000 watt amp. are the fuses the only way to really tell if it truly pushes 1000? but now i'm wonderin if maybe the guy that had the amp before me may have accidentally put the wrong fuse in the amp. would that hurt performance? and would the wrong fuse even fit? kinda new to all of this.
