Hey everybody,

I am in need of a router tool (and someone to help me use it preferably) to open up my subwoofer box by 1/8" all the way around so that my new subwoofer will fit nice and snug.

Blue circle - stays
Red circle - needs to be opened up 1/8".



I will pay you for your time!

If you're willing to bring it to Frederick I've got the tools needed and it shouldn't take more than 15-30 minutes. No money needed.

Just get a 1/8 or 1/4 inch piece of MDF and cut the hole a little bigger, just the size of the total diameter of your sub, then attach it over the front face of the box.

Looks like you have it covered already, so that may be a pain in the as.s for you, but it's a much better option. If you can get away without thinning the surface your sub attaches, to that's better.

Actually, looking at your picture, it seems the hole is already routed out. So you just need to rout it a little more? Like the sub you're putting in has a bigger lip than the sub you took out? If that's the case, nevermind. I'll leave now.

Exactly. The new sub has a wider lip, ever so slightly that it won't fit. It's designed so the sub sits in and appears flush.

The inner lip that is uncovered sits about 1/2" below the top, carpeted layer.

Thanks Justin, that would be a big help!

Here's a different take on what I'm working with.

After looking at it a bit more, there are two ways we can do this. The first is to use my existing tools and freehand it. Should look ok, won't be quite as tidy. The other is to purchase a router bit specifically designed to make this kind of cut. It'll have a bearing on it that will ride on the inside lip of the hole and will make a really nice, clean perfect cut since we can do it on my router table. It'll also reduce the time it takes to do this to about 5-10 minutes. I'm great either way, up to you if you want to spend the dough. The bit will be something like $25. What is the distance from the edge of the hole to where you want the inset to end?

I made a quick template on paper, and the outer rim needs to be trimmed about 1/8" all the way around. I think what we could do is do an exact measurement, taking into account the width for carpet too. We could pull back the carpet, draw an outline on the board,and trim it to size. If we could use your tools and avoid the cost of buying a new bit, that would be fantastic!

If we're going to freehand it we don't even need to be that detailed. Simply drawing the line we're cutting to and taking it slow should be fine. We'll likely use a Dremel with a routing attachment for this. Easier to use for small jobs and should cut MDF just fine. I've also got a router if we need one. This may give me an excuse to pick up a laminate trimmer, as that would be the perfect tool for the job.

any steady hand and a jigsaw should take care of this very easily.. I dont see the need for routers, dremels and bits.. take your time, and cut on the line.

a jigsaw was my first thought.

Jigsaw won't work. He's trying to leave a lip to inset the sub into the front of the box. At least that's the way I read it.

I didn't realize he still wanted the lip. I have a router but I'm lacking the bits to do that.

Let me know if this clears up what exactly I need to do. Think we can manage this, Justin?
