Shouldn't be too bad a job provided i can get 18mm plywood in town, which i see as the bigger problem so hopefully mitre 10 or home hardware will have some when i look tomorrow. Then its just a matter of removing the old piece, cutting the new piece, getting the joints right then attaching it. Cabinet is bare right now, just have to detach the backbox. The sub is absolutely perished so i'll just have to put up with the pinball pro speaker kit (sarcasm :P) after hearing the difference of it in my dr who i'd love to put the kit in every dmd i buy.
