A:AnswerI would hope not. This thing is massive and who pays for the labor of lugging it around/repackaging it. Furthermore I would not want your used goods unless I knew I was purchasing open box at which time it costs less and who pays for this loss?
A:AnswerOur JBL PartyBox 300 has an RCA input that can be used to connect another speaker using the "daisy-chain" method. The mic input is for connecting microphones. Unfortunately, an audio mixer can't be connected to this speaker as the inputs on our PartyBox is not designed for it. The frequencies of this speaker are pre-set and can't be further modified. There's no need for a pre-amp because this is a plug and play unit. For more information, check out the specifications here: http://bit.ly/2KkbgW2
A:AnswerNot all songs have the same volume and it's possible that this is the case. However, if you're playing songs from a music player (i.e. Spotify) and the volume adjust differently on our JBL PartyBox 300, please contact us so we can help you. https://bit.ly/2zwFkYM
