Very nice design . I’m curious about the final result. And I can assure you: this boombox will be heavy . My smaller boombox (40x25x18cm, made of 15mm plywood) weighs about 9kg.
I think it’s a good idea to use the 2.1 plate amp instead of the standard 2.1 amp. You will have plenty of space on the back side for it and will not need to worry about where to place the controls and connectors. This is always a headache when using the 2.1 amp. However, I would try to place at least the status LED and the IR receiver in the front panel (maybe somewhat hidden) and use the remote control that Arylic offers or the smartphone to control the boombox.
Since I have a 2.1 plate amp lying around in search for a project, I might steal your design when you’re finished .
I do not plan to move this around a lot, so weight is not a problem
In this project I focus on design + sound qulity - I have tested my 2.1 amp in combination with the DD elements and it sounds great.
Ill share my design files when im done if anyone is interested
I have the remote… so I`ll try to add them
Anyone have the 2.1 plate amp as a 3d model (step) file? or the measurments for the plate with screw holes?
The plate dimensions are 134x149mm (HxW). The three horizontal screw holes (on top and bottom of the plate) have a distance of 69mm (center-to-center), the three vertical screw holes (on left and right side of the plate) have a distance of 61mm (center-to-center). All measurements done by hand. Hope this helps.
Just a small tip: There are people that used one RGB LED instead of four individual mode LEDs. Could result in an even cleaner design with only one hole needed. Searching for ‘RGB’ in this forum will lead to the respective projects.
You’re right, with a classic RGB LED without any additional logic you can only display three modes (+ LED off). So you could either build an additional logic for white (= WLAN) that activates all three colors (that should result in something “whiteish”) or you use an RGBW LED (with an additional pin for white). For example, see this thread: https://forum.arylic.com/t/black-red-with-2-1amp-inside/902
Nice rendering . I do not see any benefit from using an isolated section. To the contrary, you may run into heat problems and take away some of the internal volume needed for the bass. In my boombox, I did not use an isolated section and did not notice any problems yet. However, I secured any internal connectors with hot glue. I even have some relays in my boombox and was worried at first regarding interferences with the bass at high volumes. However, did not have any problems yet.

next, installing the plate amp…
