Using this speaker is a breeze. First, connect the JST 2PH input cable to your audio source. It can be used with our mono audio amps like PAM8302 or MAX98357A for great sound. When mounting, use the 3.4mm diameter holes and the 24mm x 63mm rectangle as a guide. As for maintenance, keep it away from moisture and dust. Don't expose it to extreme temperatures. If it gets dirty, gently wipe it with a dry cloth. That's all you need to know to enjoy your speaker for a long time.
