VERY NICE,GREAT PRICE
I do not think you will find a better distribution block at this price. It really does look great and even comes with a complete extra set of set screws and allen wrenches

Hooked up 2 car amps. Works Great!!
Ordered up 2 of those under the car seat woofers with the built in amps. Installed this power distribution bus bar system, ran both amps through it and it works great. Super easy to install, holds up very well so far with solid connections, fits almost anywhere it’s not big, makes it easy to clean up the wires and make them look nice and neat, and it’s well worth the cost. Just remember if you do decide to hook up multiple amps or even just one that you are using the right size gauge wire, fuses, and the right terminals if needed. I saw that somebody melted theirs and I’m guessing it was not a clean install and probably had it fused and wired incorrectly. Overall super happy with the product, well worth the price, very durable, and I highly recommend it.

Solid Power Block — Easy Install & Works Great
This fused power distribution block was exactly what I needed for my car audio setup. It’s sturdy, easy to install, and keeps my wiring clean and organized. The fuses fit tight, the cover snaps on well, and everything feels secure. Perfect for amps or accessory add-ons. Great quality for the price!

Great product! Slightly longer than I’d like to remove the ferrules
Great product works as described, mounted without any problems, only issue I ran into was removing the pre inserted ferrules from the block to utilize a larger gauge wire. Outside of that it’s a great and definitely would purchase again

Best product in its class.
I’ve tried the name brand one, a second “knock off” and this one. And out of all of them this one is THE BEST. I promise you. I’ve bought 2, because the first I Iiked so much I thought many the name brand one will be better but saw it definitely wasn’t. Coil. Then tried, to check a second brand clearly a knockoff with the Lead lights and it was poorly plated. When I say poor quality I mean very poorly played, if played at all. You can clearly see that some part was played and the rest barely. It was like a blind person played the name brand version. This “knock off” is the best I’ve seen. Just my 2 cents. Picture included is this brand. It is fully plated and not half plated or “brushed. Even the brushed version, coil, wasn’t evenly brushed and looks absolutely terrible. Maybe for a layman it looks good but to me this is just the best in quality. Hope this helps.

Good fuse block, connections are good. Encapsulate case and cover works as designed. A bit delicate and for somebody that is Tammy or impatient it might break.

Great fuse box for sound or lighting projects. Mine one is hooked to two amplifiers(2000w rms total), one pioneer stereo, and the power supply. It works great!
