InstallGear 4/8 AWG Gauge AGU Fuse Holder Distribution Block (60A) 4 Gauge in to (2) 8 Gauge Out | Fuse Block for 4 Gauge Wire/8 Gauge Wire - 60 Amp Fuse Block for Auto, RV, Motorcycle, and Boat

I used this to power a set of dual compressors for my air horns on my truck. Works perfect to reduce and split, went from 4ga to 2 8ga. Super easy to use, I like how you can put the input from different directions if you want. It allows for flexibility in mounting as well as helping with keeping the wiring neat.

Super easy to install and use. Ended up using zipties through the screw holes for my install and it wasn't an issue. I like that it accepts the input wire from all 3 sides. Outputs fit my oversized 8awg without issue. Quality of the parts and finish on the metal was higher than expected. Only downside is that when screwing down the wire, the output blocks felt a little unstable and may break if you torqued on it too much, so use caution when you do.

This unit worked great. I use true 4 awg in but true 6 awg out. It's oxygen free stranded copper and I thought I might have to bore out the two 8 awg blocks to fit it but it was just big enough to fit. Made for a good tight fit. Mounted easy and looks really good. I replaced the 60 amp fuses with 50 amp since my amps are only one 500 watt rms mono and one 4 channel 75 watt rms. The only con would be at the input. The two side holes are not a good idea since it keeps the stranded wire from making a tight fit. This was remedied by inserting a solid copper strip over the cable and having the set screw push it onto the stranded wires making a really good tight fit. Aside from that I'm happy with this unit.

I needed to split off of my battery to lead to two (2) separate amplifiers but I didnt want to spend a ton of money on a simple splitter. I was very happy to find this product which not only provided a fused connection but was pretty much the cheapest price I've seen. The splitter is small but left enough room that I was able to run my 8awg and 4 awg wires into the connections with no problems. I really appreciated that the 4awg end lets you insert the wire directly in the back (like you see on the 8awg side) -OR- from the side which is what fit my application perfectly!! (Pictures attached) I was able to run a short 5 inch length of 4awg wire off of my battery in a 90 degree and stick it through the back of the splitter sideways. I then ran my two 8awg wires out of the top and curved them to the side so they could run into my fender. I really loved having the fused connection during set up as it allowed me to hook up and run the power wires right away but, I was able to remove the fuses and reconnect my battery terminal. This allowed me to drive my car around without having hot power wires flopping around while I finished the install. I also like having the the second set of fuses in the run as an extra (easily accessible) precaution.

I received this order with two 60amp fuses which i didn't realize was about 60amps more than my system requires. The seller sent me 4 30amp fuses for free. I appreciate when sellers do this kind of action on a product. The Fuse/power distributer is well made and works great in my system. Thanks again.

This fuse holder worked perfect after a small tweak to the contact spring for one of the fuses (it was not tight enough of a fit for the fuse to make a good connection) but after that everything went together smooth. The final setup looks really nice with this fuse holder protecting my amplifier and electronic crossover that power the subwoofers enclosed in the box.

right size right part

Good distribution fused block, you can actually get a #2 wire on the input side and #6 on each of the two outputs. Nice to have the two side holes on the in to help with connection angle but would have liked to see some type of block off plate for the unused ones, bare metal with that much amperage running to it just sitting there begging for a wayward screw or some other conductive materail makes me nervous, I cut some clear plastic to cover the two unused holes. They didn't have a 50amp version so I got the 60 and 4 pack of fuses, can't hurt to have a few extras anyways.
