I also did add plexi cover in front of led, which I dig and easy to install. The local hardware store had small pieces off plexi, a plexi knife and some super glue.
Also I had a pre-sleep dream the other day about connect some sort of speakjet module to the d-sub. Would that be possible or am I just dreaming?
If you have enough juice left to power a core, and speak jet module, and enough space to mount them some way into the mb-6582 then id say its possible.
