[QUOTE="balenim1000, post: 361684, member: 11071"] I am thinking that it may be the board. The power side is totally separate from the audio side. I am using the same parts as listed in the OP apart from the amplifier board which I got from Jaycar. and is the arduino-compatible-2-x-3w-amplifier-module/p/XC4448 Power is supplied from the detector battery into the booster box with pass through to the SD2000. 6v goes to the regulator and 4.99v after the regulator which is supplied to the module. I have a 10k pot on the input side for the volume, and out put straight into the 6.5mm Stereo Socket for the speaker. I can't find any shorts, and the negative side of the power doesn't come into contact with the ground of the audio side. I will try the new board when it arrives to see if that makes a difference. Thanks, Andrew... [/QUOTE]
