What router bit to cut speaker holes?

[Based]

I have been looking at videos of people using jasper circle jigs but nobody says what but they're using. I just bought a Ryobi plunge router for $100 and the $60 bit set. It has straight bits which I am thinking is what I need to use.

Yes and you can make a jig out of masonite hard board to cut the holes too or if you plan on cutting lots of hole the jig would prob be best best. I personally never owned a jasper jig but looks cool. I made a masonite one and never needed it. If you want pics message me its real simple to make and use.

You need a 1/4" spiral up cut bit for holes with the Jasper.

Spiral UP? I was researching and I found the guy from Car Audio Fabrication saying a spiral DOWN bit. And of course Home Depot only had the up spiral bit.

I haven't done anything with my current box build yet though. So if I can use a spiral up bit then I will get one.

I've always used up bits, just got 2 in the mail, matter of fact. The ones at home depot are pretty decent though.

What is the difference? I read that if you use a spiral up bit with the router facing downwards, it creates a kickback?

Never had a kickback ever. The difference is it clears the shavings out as I cut by spitting them up and out.
