It is from the flexing of the panel that the amp is mounted. Do not mount an amplifier on your subwoofer box.

Mount amp to sub box. So for me i just love my car. If at all possible avoid mounting any amps to enclosures. Use 1 14 inch pvc conduit for a 100 amp sub panel or 1 inch pvc conduit if the sub panel is 50 amps or less. You could put the box on blocksstilts and put the amp underneath the box. The only way to do this was to mount the amp to the box itself. Do not mount amps to the sub box amplifier mounting.
Meades setup is different he has very little flex from over building his enclosure. The proper way to mount an amp to a box is to get the amps mounting points as close to bracing as possible since that panel will not flex as much. As soon as you mount the amp to the box the amp board and all components absorb every bit of vibration. Run the conduit from the garage to the main panel box. The flex of a poorly braced box will cause the vibrations out of the box. You should properly secure the subwoofer in the trunk by using wooden plates.
I then dont tighten the screws down completly tight just enough to keep the amp in place. Otherwise the safest way to mount the amp to the box is to double or triple baffle the area the amp will be mounted to as well as maybe a foam board or some rubber gaskets to further reduce the vibration. I know that there has been a great deal of discussion over mounting an amplifier to an enclosure and many people do it all of the time with no problems but those people probably build good enclosures from 34 or thicker mdf with extensive bracing. I absolutely definitely love it. Dig an 18 inch deep trench for the outdoor electrical wire which you will run from the main panel box to the garage sub panel. Vibration shouldnt be a huge problem unless the amp manufacturer didnt account for it when designing the solder joints.
Yes you can mount a subwoofer box in the trunk by using stripes bolts multiple hinges wooden base and metallic plates. I dont drill the screws completly through the box. It is very bad for the amplifier. The real problem with mounting an amp to a box is the box flexing if not properly made. I also put a foam padding between the amp and box to protect the amp from vibration if any. Cut out a piece of wood to mount to the box then mount the amp to that panel and use rubber grommets in between the panel and the amp.
