Look great
These are absolutely fantastic inline fuses for your amplifier or battery hookup. I got the two pack of 200 because I am running a 4,000 watt amp that requires two separate positives as well as two separate negatives. They are the perfect size and easy to change the fuse. The top comes off easily. It comes with the tools you need to put the wires in or take them off. All in all, I feel like I got a fantastic value with these and I would definitely buy these again.

Have these connected to OFC 0 gauge wire running nearly 10K watts they handle it perfect!
It’s been months since I bought these and I run one coming off my main battery and then another on my auxiliary battery. I’ve got a huge alternator and running nearly 10K on my set up before I even started to think about what Speakers size or anything like that I made sure that the power and wiring is gonna be top notch. I see almost no voltage drops have not had a problem with these whatsoever.
