I didn't even think of that.I don't know if I did it would apply to exactly what you are doing. I would suggest you get it working component wise - blue tooth board-speakers-power supply and add on to your design - ac charger or USB charger to the design and keep going until you are complete.

Forgot to ask -If you have the have a headphone jack plugged in it will disable the blue tooth.Do you have the volume up on the phone?My device id is: KRC-86B V4.0
Looks good!Did you use the same Bluetooth amplifier I did? I've tested mine with like 5 different devices and I did find one that it wouldn't work with. Funny thing was it was a brand new Samsung phone.If it is the same one as I used, you can contact the seller and they are very responsive about answering questions.
Yes via bluetooth or headphone jack.

Well since I've posted this instructable I've been using the boom box off and on every couple of days. I originally charged the battery when I started the project and now I've used it for at least 6 hours and I haven't had to charge the batter yet! So the 5ah battery is working out well. I've also had it connected to three different phones and there were no problems with them connecting via bluetooth.
Bluetooth range is limited to maybe 10 feet and in the same room. I really can't complain since I have the amp/receiver locked in a steel box.
Wow - good to know! I may order a spare or two.I ran it at 20v and the performance was much better. Not that it isn't very good now. I suppose I could go with a double 12v batter solution. I would have to figure out the space for the 2nd battery, how to charge both of them and make sure the 12v car charger will still work. As I mentioned in the build to get any decent Ah out of Lipo batteries would of cost as much as the rest of the components.
No, no hum with the bluetooth. I do have kind of a hum when I plug in the the cord for the phone charger and use the audio jack from the phone to box.
