If i put too much input signal into my little amp will it burn? Answered
I'm building a 5 speaker boom box out of a heineken beer keg. For the input interface and amplifying, i'm using an old pc speaker amplifier circuit, and i want to do the following changes to it:
Put 3 input jacks, altogether (plugged into the same spot of the circuit): 1x 3.5 mm jack for mp3 player input. Kind of Aux input.
2X 1/4" jack for two guitars or another combination of instruments.
Put another output jack, 1/4", additional to the 3.5mm already there.
Questions: If i plug too much things in will the amplifier burn or explode?
Will it be able to drive 5 speakers (1x 1.5", 2x 2" and 2x 4" approx.)
Other info: it runs with a little transformer of 220v/60hz to 9V DC. The speakers were rated to 110V/60hz. Does this means it acctualy runs on 4.5V DC?
