The Streetwires CBXS024 fused distribution block offers an ideal solution for anyone who needs efficient, protected power transfer to up to two amplifiers. This versatile combo block provides both positive and negative connections that can function as inputs or outputs, useful for a wide range of applications.

The CBXS024 features 4-gauge positive and negative power terminals for connecting up to two amplifiers. You'll find 4-gauge power and ground connections for the cables that run from your block to a battery or capacitor, along with positive and negative Power Ring slots. The fuse holders can handle AFS fuses ranging from 40-150 amps.

Streetwires machines the block from solid brass, then coats it with corrosion-resistant, Diamond Plate Nickel for outstanding current delivery and low power loss. Clear, impact-resistant quick-release covers allow easy access to fuses, while steel spring-clips make sure your fuses always maintain solid contact. Your power cables stay secure in deep socket compression-screw terminals. Warranty: lifetime.

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.
