Router or Roto-zip. Either with a circle cutting jig.

My personal choice is my trusty router and a jasper circle jig. :)

If you cant afford a router and circle jig, a good ol' high speed jigsaw kicks bootay.

You just use a Compass for Diameter? I drew mine out. Does RE send Templates with the subs when you buyem?

Nope. But on their website under Tech they tell you the cut-out hole diameter.. then you can divide that by 2 and set your compass with a tape measure.

Thats what I did... no router here.

i don't know bout rotozip, seems like it would take all day.

I tried it, even when going slow managed to burn my mdf.

I'd recommend a router or jigsaw Def.

can get one for 20$ at hardware stores

Just ordered my jig for the router. Just need a plunge base for it now. Sounds like a trip to Sears is in order for tomorrow.

As for the RotoZip, I know that is what Lloyd used on the 20 8's so it must not have taken TOO long :D. I've yet to try mine out (crappy weather :()
