This is a pair of speaker boxes that came out of a customers MG.  The hole in them is 5 3/8" probably for a 6" round speaker?  They have external hook ups with internal leads to the speakers.  The dimensions are 9 3/4" x 8 1/4" on the front, 7 1/8" deep,  9 3/4" x 5" on the back
Carpet needs cleaned but other wise nice condition.
