you read my mind, the theme is pretty much what you had stated. i want clean and classy.
Unfortinately phaze isn't in business anymore, these amps were actually made by bk butler, but he only fixes these now...he won't be able to get another amp shroud (if you look at my original install you can see i went that route before)
The new design won't cover up the whole amp (maybe that was a missunderstanding) the whole amp will be exposed, but the tops are goign to rise above the floor. it's hard to visualize but it actually looks good to me in my mock up. I do like your smoked plexi/lights idea. i had originally thought about adding some lights to accent the amps, so i think you may have nailed it. and i'm definately going to take your suggestion about routing the edges with a nice 1/4 round.
It's hard to see it, but the walls in the pic above are at about a 60 degree angle; but yeah, you have it right going with a nice bevel. it'll make the whole piece look sturdier too. the top piece is 1/8" hardboard, i bet with a nice piece of 1/2 under it and routed will give the impression of a beefier install w/o the added weight.
tthanks for the good ideas
