Just a question. I have a JBL partybox 300. That box is 120W when connected to 220V wall adapter right? So if i put this thing in my car with a 12V conection will the speaker run at its 120W peak or wil IT run at lower wattage (same as on battery). Wil putting a 12V to 230V transformer fix this issue so i get the full 120W of power.
Or do i need something else.
Let me know.
Thanks in advance
