Introduction: Plexi-glass Box 4 Home Audio Amplifier With Power Supplay
Home made Plexy-glass box with power supply and audio amplifier.
The idea was born because in house cinema I had no SUB. The system is 5.1, but the SUB was not amplified output. Variants have been two. Buy an active SUB, or just bought an amplifier and make a box
First of all, I bought 2x50w Class-D amplifier, which has a working range from 10VDC to 26VDC for less than US $7
Of course, the 12V power supply has much less gain. But the test was authorized.
So I made a small body of plexiglass. Most of the material I picked up from my workshop :) so that the product is not exactly profi
So ... the circuit is assembled, but not in the case. In the garage I had some plexi glass panels. Dimensions were appropriate. For plexi bend several variants of. it can be bent with a strong blow dryer or use of the filament (video)
And in the end it was necessary to have all screwed to the chassis. Again, I used the resources available in the garage. Some of the spacers, some wire and that's it.
