i folks, I got a Sharp GX-300 but as I was pumping the boombox to listen to the sound quality the speakers started to break apart. Now I would love to have them refoamed but here in New York City there aint any and would love to change them but I dont have a clue on how to open the speaker caes so I can replace the speakers, Any member here have this GX-300 knows how to open the case. Please help. Thank you folks.
