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
