What ones are you on about? The bazooka tube shown in a different thread or one of the ones above?
The ones i posted above were all custom made.
Only place i know of at the moment that does off the shelf ones are basic square boxes or a company in the Uk called autoacoustics http://www.autoacoustics.co.uk/sbn-vg05.htm im sure theres a similar company overseas. Or im sure a local car audio dealer would do a better job like the one i posted above with the JL sub in.
The photo below is perfect for my carputer. Does anyone know if this storage unit can be bought or again is it custom made? and if so can it be made again
Uh huh.....How are you expecting the free airs to work? I asume that is what is installed in the shelf. You must also get some hellish vibration on that back shelf area.
