    I need someone to give some advice to a noob at circuitry. I'm attempting to rewire a megaphone circuit. This requires me to elongate the wire of each device (the speaker, the microphone, the buttons) and I only had a thicker solid type of wire to use to elongate these wires. Right now, the whole thing is finally rigged up, not working properly. The tea2025n logic chip (amplifier) is getting extremely hot, possibly overloading. Is this because I'm using thicker wire? Or another reason?
    A little more info: The circuit board for the original megaphone was designed with 6volts (4 D batteries) I switched this with C batteries for size. The original megaphone automatically turned on the microphone with turning on the device, but I added a trigger to it to open the circuit btw the microphone and the circuit board. I also added a audio input to the megaphone.
    maybe this additional info might help diagnosis the problem

    Changing to a thicker wire is not the problem.
    Changing to C batteries is not the problem, though this will reduce your operating time.
    The problem must be some other reason.
