06RTCharger noobs first ever build

Continued...notice how the top right rivet location is located on a panel that has a bend so its not flush with the rest, meaning my adapter needs to bend. Second pic shows what happened when i tried to use a heatgun to bend 1/4 hdpe plastic, turned out hideous. Also notice the messed up lower left hole in the plastic adapter, i made the drill hole too large for the bolt so i thought i could attach a small peice of plastic ontop of the hole and redrill the right size hole. I tried to use mobile solutions CA glues, didnt work. Hdpe is a very adhesive resistant plastic, most glue/epoxy/adhesive containers are made of hdpe... so yah that didnt work out nice.

Heres what i used to put the rivet nuts. Another tip, DO NOT use a spiral drill bit to drill holes into ur door when there are things behind the hole location. Once that bit breaks slightly through the back of the metal, it WILL SHOOT through the panel like a spear, because of the speed drilling through the metal. So i use a, i think its called a uni-bit. Looks like a christmas tree bit.

Since that bend didnt work out i decided to relocate that mounting point by installing another rivnut on the flush section of the metal panel. And cut new adapter plates so it doesnt look all fucked up. That football shapled hole is to fit a metal pump that stops the adapter from sitting flush againstbthe door so i cut that out so i could make it flush.

Perfect fit

Alright so the plates are done, onto to rings. Again very glad i made a barrier to contain the mess.

I fucked up on my elementary grade math lol. using the jasper circle jig to cut "DISKS" (not holes) you need to just add 1/4 to your desired size and thats the pin location you use on the jig. I added my fractions slightly wrong and ended up with the speaker slightly hanging over the ring :/ also i used threaded inserts which i thought would work well. But because of the softness of plastic the insert had a hard time staying straight, the insert would easily go crooked when inserting them into the plastic. Also because my ring was smaller than planned the insert was almost cutting through the outside edges of the ring.

Ring and plate. Cardboard plan comparison

Polycorbonate tube to cut the mid section of my adapters.

I messed up the second pair of adapter plates by trying to make the hole countersunk for the bolts, so i ended up ordering more plastic and making another. My 3.0 version lol

[06RTCharger]

Wasnt happy with the first version of the rings so i ordered my plastic and made another version, speakers flush mount inside the rings. Using 1/2 hdpe plastic sheet. Also i didnt like those thread style threaded inserts so i did some research and found that "push" inserts work well with plastic. So you can see the ones i got and the work perfect. Also these inserts are available in shallower bits, the others i used only had 1/2 depth as the smallest. I needed smaller. And also i wanted to use smaller fasteners becuase the head of bolt wouldnt fit into the legatias countersunk holes(they come that way). The first were 10-24 thread and they were way too large for my 4inch speakers and had to be forced into the L8SE. So i got 8-32 threads that fit perfectly in both speakers.
