Works
Wish I had gotten two but it works well carrying the power to the amp

Good product
I would recommend this product because it makes a good connection instead of trying to stuff the 0 gauge wire into a 4 gauge terminal. You need to have good clearance between the positive and ground on the amp for these to work so check before you order these. I had to slightly modify mine to work

Very durable and works like a charm
These things are true 4 gauge so make sure your amp has true 4 gauge inputs or it has to be grinding down. It works great and love the quality.

it's too big
Its too large for either a crunch or hifonics mono sub amp that says the size cable they can use to power them is 4 gauge but these didnt fit , had to grind mine down too fit, cuz I am obviously using them to connect 1/0 gauge wire too an amp that it didnt fit, overall , good product , looks professional when you are showing it off even after grinding on them

A Must Have
Besides how bad*ss these things make the install look, they definitely serve a purpose. I do believe I am getting a far better connections with these. I picked up Six of these for various parts of the install, and I LOVE the look. I plan to get a few more for the next step of the install.

stinger spt51 0 to 4 gauge input reducers
These are great! True zero gauge to 4 gauge input reducers. only down fall is that they need to be ground down to fit lower quality amplifiers that dont have true inputs.

True to spec
Amazing quality will not strip out, High quality metal. Highly recommend these if you need them.
I have used cheap reducers in the past that costed double the price of these and these are by far much better.

Does not fit
I bought these for the hifonics x2200 amp and they do not fit the 4 guage terminals. Also, the x2200 wire terminals are angled and you would have to raise the height of the amp a bit in order for the amp to even be mounted to a flat surface.
These are good quality adapters but do not work in my situation!!!
