Alright I am bout to end this session of hidden compartments.......Ok since you use a flask.. I say modify your sub box. Take subs out and build a little cubbie box inside and insulate the inside so no rattle from bass. Get some of those push magnet strips(those push to open/close ones) and make sure the carpeting on box is as seamless as possible. Oh yeah when you arrive at the party just throw you alittle crushed ice in flask and pump up the volume...."Shake and not Stirred Baby!!!!
