Perfect product

Perfect for me I have 2 amps. 0 gauge ran to stinger dis block and exits 4 gauge to sub amp and 8 gauge to 4 channel amp running interior. Works great!

works

does what it was built to do period. clean look tight connections

Great product

I purchased 2 of these and they worked beautifly on my setup. Looks nice as well . Would buy again

awesome

worked exactly how it needed t and saved me from having to buy 2 wiring kits

Great Product

I needed this product to install a capacitor and an additional amplifier for my mids and highs. It works perfect for what I needed to do. It also looks professional and neat/clean.

Solid, easy-to-use distribution block

I'm using this for my ground distribution block since it doesn't use fuses.

There's nothing special about the look/design, it's small and simple.

Will update if I run into any problems with durability but I don't see this having to withstand much.

It's a simple set screw distribution block, it's got some holes for you to screw it somewhere and can fit whatever gauge you need.

I didn't have any problems setting it up for my 1/0 gauge and two 4 gauges.

For the money this is a simple, easy-to-use, power distribution block. I'm using it for my ground distribution block.

Very nice

This is a great distribution block for grounding. I would not recommend it for power distribution.

Awesome product

Would recommend these, they worked perfect for my 2 amp install have a 0 gauge main down to two 4 gauge lines to my amps. Bought two of em to use for ground and power. Work perfectly. Would like to note that you have to unscrew the allenwrench head bolts that hold the wires in all the way out and pull out the "adapter" piece to make 0 gauge fit right same goes for the 4 gauge on the other end.

Pretty nice

The power distribution block says it's good for 1/0 in and two 4 gauge outs
If you have good power wire you will almost certainly have to trip the wire down to get it to fit properly. It should be fine for 4 gauge in and two 8 gauge outs.

Nice quality and small

This is a nice simple product it has 1 1/0 or 4 gauge input and 4 or 8 gauge output. Its nice an small if you have limited space.

Very Efficient

I am using one of these for power and ground with 4ga ofc nvx wire going through both and it works perfectly. I didn't have much room on my amp rack for distribution blocks so these small but efficient ones were a perfect fit. I'm using 4ga input splitting to 2 4ga output and there's no problems I can see. The low price is also a plus.

Perfect

Needed a block to spill it my 0g ground into two amps running one 8g wire and one 4g wire. This definitely did the job.

Good stuff!

This item did exactly what it should. Great value. I would definitely recommend!!

Stinger SHD20

Stinger makes high quality gear, and this distribution block is no exception. Highly recommend!

Stinger SHD20

The Stinger SHD20 is a power/ground distribution block. I am currently using it as a ground distribution block since my power wires are different sizes and I need a fused distribution block for my power. I would recommend this product if you are running it as a ground distribution block or a power distribution block if you plan on using the same gauge wire.

Multiple amp must

If your going to add multiple amps, do it right. This is a great way to split the power efficiently. Good quality product.

Adapter Rings PITA

Does what you need it to do. Just wish the adapter plates didn't come already installed. Smaller ones came right out, had to force the large adapter out as it was stuck. No complaints on quality of the actual unit.

Good

Good quality - works fine. Don't cheap out on electrical items get a good one like this.

Solid Construction

Ordered these to add an additional amp in my boat. These Stinger distribution blocks seem heavy duty. I would recommend them.

Stinger FTW

Stinger has the best install products! They never let me down!

Good price

This terminal block is good for the money, except the only problem is that the plastic cover oftentimes falls off when bumped. A bit challenging to reinsert, however once the metal piece is centered on the lower plastic piece, then all is good.
This product did not exceed my expectations, thus, a four-star rating.

Exactly what you would expect from Stinger
