A:Answer Yes it does have an aux input. It’s not 3.5mm though. It’s L & R rca type inputs. You just need to get a cable for your particular need. I used my tv 3.5mm out to the L & R here and it worked great.
The loudness of it is kinda hard to say. It was really loud when I tested it in the store which is a big open area. But if you’re in a big hall for like a wedding or something, this probably won’t be quite loud enough. But it’s great for a game room, garage, living room, or take it camping with you if you got power. It has nice handles so even though it’s heavy, it’s easy to move.
