Review on 🔊 Alpatronix AX500 Waterproof Bluetooth Speaker 60W (80W Max), Portable Wireless with 8000mAh Power Bank, Handsfree, Shockproof, TWS, DSP, Stereo, Subwoofer, TF Card, NFC - Black Gray | Suitable for Indoor & Outdoor Use by Danny Badasz

I actually attached this with a 4" wide x 8" long strip of strong Velcro between the front and back seats of my golf cart. I didn't want to have those massive stereos hanging off the roof of a train car because I think they look ugly lol. The sound quality is great, I've been using it for about 7 hours at about a quarter volume and all the battery lights are still on. He also often bounces around like a golf cart, doesn't have the best suspension in the world, and doesn't seem to bother him in the slightest. The sound is nice and clear, rich and clear at any volume, I would buy again anytime as I am more than happy with the sound quality. To be honest I think an improvement would be to add a shuffle or shuffle mode when playing from USB just like any other music player I have, in cars, motorbikes, mp3 players etc. These Feature is there so I'll forgo it t think it's probably a big deal to add. If this feature was there, it would be the perfect speaker system. As it stands, it's still pretty damn close and you won't be disappointed. I even think you will be amazed!
