XFMANL 0/4 Gauge AWG ANL/Mini-ANL Modular Linkable In-ine Fuse Holder for Car Audio and Marine Audio

Cover was very difficult to remove. I ended up having to use a small screwdriver to get the last tab to release. When I got i apart I noticed the cover had a bunch of burrs on the tabs that were causing it to bind. I cleaned them up with some fine sandpaper. Works much better now.

This single fuse holder has so much potential. Alone it can be used with either ANL or MANL fuses. It supports 4ga wire or remove the adapter and insert 1/0 ga wire. The magic happens when you combine two or more of these to create a fuse block that can be configured to virtually any use. You can parallel two of them and attach a bus bar on one side then connect 1/0 input and have two 4ga output. Connect multiple units and connect bus bars at all inputs to create a ground distribution. These will be my go-to fuse holders from now on.

Amazing quality and the best thing is I can link them together

These are nice and solid. The bus bars are thicker than I thought ( which is a good thing ). They stack together simply, and give you nice options to create a block with some that are fused and others that are not. I have recently bought various nvx items from wire to capacitors and this now. I have yet to have a reason to say anything other than nice things about the products. Have not installed the CAP yet, doing that next week. Thank you for making this innovative product.

A little confusing at first glance... but after you understand them, they are really neat. Sturdy and solid materials. I set it up for having 1 fused connection and 2 unfused connections. Lots of possibilities of configurations.- UPDATE :: I had been fighting a voltage problem at my equipment in the trunk for a very long time. Once I replaced the wiring my local shop put in, I realized they used CCA . Went from 12.3V in trunk (11.0 when the bass drops} to 14.2V, and 14.0 when the bass drops.
