Q. I see that the dimension for the amplifier / speaker is 66mm but would that be the size for the hole in the acrylic if the speaker is to be inserted? I want it to be precisely made so it doesn't look shoddy. Using laser cutter for acrylic
A. Hi Gemma, thank you for your question. If fitted from the rear, a 60mm hole would be needed.

Q. Please is it possible to fit smaller diameter speakers with this Amp, e.g. RVFM LP50028A PAPER 8 Ohm 50mm Ultraslim Paper Speaker 0.2W (35-0128) If so can you provide a straight substitute within the kit?
A. Hi A Benton, thank you for your question. The kit will work with virtually any 8 ohm speakers, however, the lower the power handling the more likely the smaller speaker will distort or be damaged if over driven.

Q. Can this be powered by a USB connection? and can a volume control be added.
Thanks. Roger
A. Hi Roger, thank you for your question. The circuit will work at 5V, however, the current draw at loud volumes may overload an already used USB device so caution is recommended. The kit is ideally used with a mobile phone/MP3 player using its own volume control. You can employ a potentiometer between pins 3 and ground of the TBA820M replacing R3 in most cases this is not necessary.
