I have. A iq sound speaker bluetooth with line in and ex dc in can I connect a regular speaker no bt to it

Solution
You can't use an input to connect a speaker.
If you want to open up the cabinet, disconnect the internal loudspeaker and connect your speaker to the same wires that would work.
Might not play very loud and if the speaker is battery powered might reduce the play time as you house speaker needs more power than the one inside the cabinet.
You can get an amplifier with built in bluetooth receiver that would work with any speaker. If you have an existing audio system you can add a bluetooth receiver to it.
