Good little block

Great product for what I needed it for. Used to divert the power between my coaxial speakers and my sub and couldn’t have been easier to install.

Great but

I bought this almost 2 years ago and have used it in 3 setups. Perfect.

Simple yet effective.

Picked up this distribution block becuase I have multiple components that needed to be grounded in my truck. Works just as it should when it comes to grounding but isnt for the "hot" side of the connection. You will need somthing different if looking to distribute power from the posotive lead. This block is strictly for grounding and does not come with fuses. Only gave 4 stars because tye plastic cap/cover doesnt really like to stay on that well. Other than that it is a solid block for no bigger than 4awg leads.

Power block review

I use this to split power between two amplifiers. It was easy to use it would be nicer if it would be in a Phillips head screwdriver, but Allen’s are fine. It did its job perfectly, and provides stable power to both my amplifiers.

Would be a 5star if it wasn't so overpriced

It's a standard unfused automotive wiring distribution block. One large wire connects on one side, two smaller wires connect on the opposite side. This one in particular is solid, from the base and actual block to the cover. However I will say this... I was in a pinch and needed it immediately, otherwise the same item or similar can be purchased elsewhere for a fraction of what Bestbuy was charging at the time.
