I kind of want to build one of these amps and connect it to a set of speaker built with these cheap exciters... One of the Youtube channels I follow messed around with them https://youtu.be/zMCyF400l1c https://youtu.be/zMCyF400l1c but he got that from this other video https://youtu.be/zdkyGDqU7xA https://youtu.be/zdkyGDqU7xA where he goes into all sorts of experiments he ran on the exciters to find the right design.
