This loudspeaker is powered by all M18 batteries & comes with a CP 2.0 battery. Looking for trades and looking for a shotgun in particular. If you have something equal value or something of interest shoot me a shot! The loudspeaker also has subwoofer inputs to connect to any subwoofer/car audio subwoofer. With the CP 2.0 I could listen to whatever rapskallion bafoonary for 4 hours with the subwoofer connected. Pretty coooool if you ask me.. could also use this on an annoying neighbor or what I used it for to call animals when hunting.. be unique n use the pros use. Or support china.. idc I’m not your dad.. btw pro car audio 8” ds18 mids Skar 2” super tweeter. (Bluetooth)
