Works well, but be careful
Crutchfield Customer Review (What's this?)
This fused combo power distribution block works very well as it is intended. Since it combines both a fused power distribution block and a ground distribution block in one unit, it makes hooking up 2 amplifiers very easy. The fact that it is fused makes it a very nice package for amps that don't have built in fuses. The only issue that I had with it was that the screws used to connect the fuses had a very deep undercut on the threads under the head; so much that one of the heads snapped off when I was attempting to tighten the fuse down. I was able to get the remaining screw backed out and after running a 5mm x 0.8 tap through the threads (to remove the excess plating) replaced the supplied screws with some pan head machine screws that I had. Otherwise, fantastic product.
Pros: Easy mounting, very easy to connect, takes up much less space than two separate power and distribution block, looks cool.
Cons: Cheesy screws, but can easily be replaced with 5mm x 0.8 pan head machine screws.
