I need to know what is the best type of speakers that do not need either batteries or plugged in an outlet.I want to use my cd player with speakers but the speakers I currently have produce ok sound but not loud enough.thank you for your advise.
the reason your speakers aren't very loud is because the cd player's headphone jack isn't amplified. the only way to get your music loud enough without speakers that dont use batteries or wall jack would be to use speakers with low ohms, but that would burn out your cd player's headphone jack real quick like.
