how can you "frost" plexiglass. i need a side of plexiglass to be smooth on one side but i need it to have the "frosted" effect on the other side.

how do you choose what farad capacitor is needed for your specific system?

yes it's a decent amp

you frost plexi by sand blasting on a low setting and constantly moving. OR you take a very fine grit sandpaper and go over it a bit.

You don't choose caps because they suck and hurt your system anyway. I can post links if neccesary

800 grit sound about right?

Higher the better. Anything corse will dig into the plastic and leave gouges
