My girl friend has a spare Lepai LP-2020A+ and she decided she wants to make a boom box out of that and a suit case. We have everything but the power source figured out. what size battery would be needed for at least 4 preferably 6 hours of music, not full volume but loud enough to be able to enjoy at a lake or camping or something. Also is there a compact AC to DC charger that could be squeezed into the case with an appropriate sized battery?
This is what I'm imagining but i don't really know much about big portable and rechargeable batteries -> http://www.amazon.com/Spypoint-12-Volt-Rechargeable-Battery-Charger/dp/B002NYN7EM/ref=sr_1_1?ie=UTF8&qid=1395801067&sr=8-1&keywords=Spypoint+12-Volt
for those curious:
speaker wise we are going to use -> http://www.sonicelectronix.com/item_61010_Rockford-Fosgate-PRIME-R165-S.html <- and I'm going to build a MDF speaker box in the suit case. I put a pair of those in a friends jeep and they have held up great to the weather so i imagine they will do fine for a cheap little boom box. also i will put a build thread together once it is finished :)
