I rigged up a radio to use while out in my shop. I bought a 200w 2-channel amp, (2) 6x9's, and just used an imput cable from my iphone. Worked like a charm the first time I used it. Now, after recharging the battery the power light comes on but it appears to be dim and there is no sound. I took the battery to the store and it checked out fine. Any suggestions of what is wrong and how to fix it?
