Hi Dan,

The MDF I used for the spacer rings was about 9 or 10mm thick.

I don't have the dimensions, but if you draw round the template in the box, then draw a circle about 8mm inside the outer circle, that should do it for the spacer.

There are three screws behind the door card that hold the OEM speaker in, which you should screw the spacer to.

One of the four screws that hold the speaker in place will also go through one of the three holes

(if that makes sense).

You'll also need to drill through the door where the other three speaker retaining screws go.

I didn't bother with the grills, but did have to trim some of the back of the door card to allow it to fit flush.

If you pop the grill out of the tweeter houses it'll leave a hole that as you say is way too small for the tweeters.

I have a hole cutter which I ran through the tweeter housing

(from the back) and then a bit of careful filing, and eventually, the tweeter, with the flush mount backing push into the hole.

It is such a tight fit, that I dodn't bother attaching them from behind.

The crossovers are in the frunk, right next to the amp.

I read somewhere that you should put crossovers as close to the amp as possible.

I didn't take any pictures while I was doing it, but I'll get you a shot of the tweeters fitted tomorrow.

Sorry if some of that doesn't make sense in black and white

- I know what I'm trying to say, but it's hard to get across.
