You just won't get its full potential out of it.(2)Q:how do you adjust bass and treble on this unit. cant see any adjustments on the board.A:There is no adjustment(3)Q:Is there any case i can put this amp in? like switch and custom case, i am thinking to use 3d printer to make one.A:Yes you can print a case. You will need some air holes and I would suggest that you put the holes directly over the three capacitors on each side of the heat sink. Then you should mount the board with the heatsink fins vertical. Total area of the fins (or slots if your'e so inclined) should be about 1.5 sq inch. Better yet would be bottom and sides without a top. And much easier to design and print.
