It looks like those screws are too small to hold those subs. I use the screws Rockford provides and have to check them every so often as they start to back out from the vibration. Plus I realized that you are only using 4 screws per sub and i see rust on some which leads me to think they are drywall screws and not exterior deck screws or something of that quality. That isn't enough to hold those subs firmly in place plus its also causing extra distortion. I bet just bumping that a few days is enough to back those screws out.
