I'm using a ta2024 amp (http://www.parts-express.com/sure-e...4-class-d-audio-amplifier-board-only--320-330) to power 2 4ohm speakers and an 8ohm woofer. The signal will be coming from a cheap bluetooth module and alternatively from an aux cord. I'm making the signal mono so that I can double amplify the signal going to the woofer by splitting the 1st channel out, passing it through a low pass filter, and putting that through channel 2 out to the woofer. The entire thing is being powered by a 5v cellphone powerbank (http://www.amazon.com/gp/product/B0...ue&ref_=ox_sc_act_title_1&smid=A1HG0SD62RRE2I) with a step up dc-dc voltage converter (http://www.ebay.com/itm/XL6009-DC-A...576465?hash=item58cbb23751:g:QMUAAOSw~gRVs4zr) to get to the needed 12v to the amp. I need help wiring a volume control as well as a power button and maybe some led lights that will indicate power and battery level. The powerbank includes a power button and led lights but since its going to be inside the enclosure, I need a way to see/reach them on the outside.This is my first electronics project so any help is appreciated. Thank you.
