Sub Pods for the Gen 2

Do any of the current lurkers know of existing sub pods for the Gen 2? Whether is a large manufacturer or a DIY audiofile, I am interested in sub pods for the compartments over the battery compartment and the adjacent one in the other corner. I am looking for a max of 8" subs in those pods.

Thanks

 

Thanks so it's off to work I go. Obviously I'm doing this for myself, regardless, I will document the journey and progress. In addition I plan on converting the rear tray to be a hidden amp rack for my modified stereo system.

Have I done this before? You tell me ..
