about sub...
First of all panels have been made of two combined 10 millimetric leaves of plywood (MDF)

Further have stuck together and have braided in pair kgs of screws, a box of the demanded volume

Has cut in a back of a seat an aperture that the subwoofer looked directly in interior, without superfluous obstacles in a way

In a ready box of a subwoofer has made 2 apertures for a sub head and for plexiglas

The case is ready

Further, the case has been processed by a spray antigravel

Has fitted in carpet (or something in this sort)

Here that as a result it has turned out. It is necessary to make the panel of a back wall with an aperture for plexiglas and to press it to the case of a subwoofer

thats all... from outside

from inside
