WTF SOUND ISSUE

I've posted this here as a temporary gallery of my Crix Sound Kit + Spongeface Battery Eliminator/Pre-Amp Board + 8w Amp. These are many up-close photos of the wiring. I will also describe the wiring of the modules to correspond with the photos, as follows: Sound Module 3v + to PreAmp Vsnd GND (red) Sound Module 3v - to PreAmp Vsnd + (black) Sound Module Speaker + to PreAmp SPK - (green) Sound Module Speaker - to PreAmp SPK + (black) PreAmp VBat+ to switch (red) to Amp- (red), connected to Battery + (red) PreAmp VBat- to switch (green) to Amp+ (green), connected to Battery - (black) PreAmp Vol-Pot+ to Amp input- (red) PreAmp Vol-Pot GND to Amp input + (green) Speakers are in parallel. The problem occurs when I switch it on; there's a steady pulsing ticking sound, and no response from the sound kit. The sound kit itself is working fine; I disconnected it and connected it to a 3V power supply and speakers on its' own, and there was non-amplified sound. I have NO idea what to do now. I'm going to delete this as soon as the issue's resolved!
