Sugarcubes and micrucubes will produce good sound levels whether located in an enclosed space or exposed on the floor of a cab for instance. Just make sure to locate the speaker with the drive unit(metal part) facing up if on the floor or down if stuck to an upper roof with black tack and ensure no live chassis parts can come into contact with the speaker terminals as this will cause a short damaging the sound circuits. It is infact possible to wrap the whole thing with kapton tape to prevent shorting and there is little or no reduction in sound depth and quality as a result.
The baffle on the sugarcube can also be removed and filed down to make a fit if necessary with little loss in sound quality, just file it to the size required and re-attach to the drive unit with a few spots of superglue having removed the self adhesive gasket(not too much glue though, a complete seal will not allow the baffle to act as a reflex port and sound will be diminished
