Hello there,
I am engaging in the world of electronics a bit to build a boombox backpack to help with promotions for my company. I have read up on a few different builds that others have done but I have questions about amplifiers and batteries.
Others have recommended getting a small mini amp that puts out like 40 watts per channel. I have seen a few of these on ebay and such but I have also seen much larger mini amps at say 300-500 watts.
We want this backpack to be very loud but we also want the batteries to last a while. I was going to get a 12v 7ah battery pack to run the amplifier. What would the power vs. efficiency equation be like here?
Basically looking for suggestions that will keep me as efficient as possible and to keep me loud but keep my going.
Thanks for any help.
