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.

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

Clean and Safe Wiring
Installed this distribution block in my home car audio system and it works great. It helped organize my power wiring and made the setup look much cleaner. The connections feel secure and the fuse protection is a nice bonus. Check my videos to see the real setup and testing.

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

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!
