    I second that, if you make tweeter pods out of the sail panels I’d buy some!

    Thanks for the enthusiasm! This is the first time I'm trying this so I'm not a pro. I want to finish this set and make sure everything is good before I even think about trying to make more.
    When I was a poor high school guy I had the budget system and always dreamed about going top of the line. Now is the time I finally get to live the dream. I'm going with JL audio's C7 component speakers. the c7-100ct is the tweeter, c7-350cm is the mid range, c7-650cw for the woofer.

    Wow! Those are some serious high-dollar beauties! Whoohooo! I cannot wait to see this! I've then gotta figure out a way to hear it! (If you're ever willing) This sounds just too cool! Keep on keeping on brother!

    small update

    Small update this time:
    Originally the idea was to use a hdmi break out to get 5.1 audio if needed when watching a movie or whatever. I wondered why there was no support for that in the car world. After talking to some veteran installers, the reason is because 5.1 sucks in a car for everyone listening and don't try to use home stuff in a car. Mixing it to stereo is a better option for everyone involved. Well, ok. (I considered a usb dac as well but the pi's usb ports are rather noisy). So now I'm getting a allo digione transport board, which means it adds digital outs. I'll run the spidif rca to the c-dsp. Toslink's are too bandwidth limited which is why they don't even have that connector on the board. The allo seems to be a little better than hifiberry's offerings but you pay for it. The digione signature is too expensive, too large, and requires 2 external power sources. Just too much for this project.

    Next, I bought some sosche SA68 6x8 speaker adapters. They claim to be able to convert out 6x8s to 5.25" and 6.5". That is a joke. There is no way in hell a 6.5" can fit. Even if you shave off material to make it work the sides would be so thin as to just break in half. I scanned the adapter and used tech specs from JL to make a new adapter in adobe illustraor then used svg2stl to make it a .stl. Then I took it to tinkercad for some quick finishing and tweaking. Below are pics of the side by side. The left is the SA68, right is my adapter prototype. The screw holes are messed up here and still need to be punched out. The next version will look like the adapter's counter sunk holes.



    Next is some fitment shots of the pods. The left has the sail panel removed but the right side doesn't. Haven't done anything else with them yet. Body filler taking years to get here...

    This is looking really good! I actually just got the custom speaker pods in the mail today. I am watching your tweeter pods with great earnest! I think I'm going with the Audiofrog 3-way speaker set.

    I can't wait to hear your impressions of the JL's...I've never heard those!

    Audiofrog was definitely in the running for me. They should sound great.

    Still working on this. I'm just lazy. Started to piece together the head unit itself finally.

    From top to bottom of the stack is:
    Raspberry Pi Automatic ON/OFF V2.1
    the allo digione
    raspberry pi 4.

    The thing sticking out the side is a nvme ssd hard drive in a usb adapter. The foundation finally released a beta update for the pi to allow it to boot from usb. Since it has usb 3 connections the load times are much much better than from the sd card. I'm still working on it as betas can be a little fiddly.
    You can see the connector on its own pcb there as well.

    Finished the amp rack. It is 15"x20" so it will slide into the shelf next to the spare tire. Had to double stack it to make all the components fit.
    I'm pretty happy with it. It isn't pro levels as you can see many small errors with it like things not centered right, wires too long or too short, cuts not square etc but this is my first build since high school and it is leagues better than screwing everything into the back of the seat in my 1983 honda (and then having everything just pull out and flopping around...)

    Wow! That's some good work man!

    I see you have your CLD on the floor there...did you already do your panel dampening? Any pics?

    What's next for this project? Mine has been in paint/body for three months...it's killing me!

    I pulled everything out of trunk, did like 3 squares then noticed some rust on some seems so off to the body shop it goes for now, which is why I started with the amp rack. The next step once it gets back is to take out the interior and deaden everything. I'll take pictures of that.
    Then install speakers with adapters, run speaker wires, finish the tweeter pods, install the door pods (blend and make them not look like crap), then finish and install the headunit and its wires. I think that is it. ya know, not too much

    Looks good. What do you listen to that requires all this sophistication? Your home set up must be amazing.
