Good luck with the tubes. They'll do something. Problem is to get them to work down in real bass frequencies, think 18-24" diameters and then fill them with regular fiberglass at a minimum.

Scott - sorry I missed your question.

Yeah - you can do that - but it presents issues since you can't have it where you have walkway but only under the seats. Then, that can weaken the support requiring additional supports. Don't get me wrong - it can be done - it just needs to be planned correctly from the start.
