Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.

Works as it should.

Great quality! Sounds great and we’ll built!
I’ve owned a couple of these larger Bluetooth “party” speakers and this is by far the best sounding and well built one I’ve owned. The last one I bought was made by Ion and was much larger, but I think this one sounds WAY better and just looks and feels like quality. The Ion just felt cheap and it died just after the warranty period (of course) It wouldn’t power up anymore even when plugged into a wall outlet. The light show is killer in this if you’re out by the pool at night. I almost forgot to mention, this thing is very lightweight, so easy to carry around. It’s a winner.
