Just arrived yesterday, so they have not been installed yet but impressed by first looks

I just bought these cables to run 2 12'' pioneers with a 2100rms class D amp, the wire is very good in size ( actual copper inside not just a oversized rubber surround) VERY flexible for the thickness it is and came with everything needed for a proper install. The only thing I would say needs improvement would be the fuse holder, it seems like a cheap plastic cover that has huge gaps on the side that could possibly be an issue if the right conditions were presented such as water somehow following the wire into the fuse holder which shouldn't happen to begin with but you can never rule anything out with cars in general especially when it comes to audio products. Overall nice kit though and would defiantly recommend to others, ( maybe get a different fuse holder if you want to be completely safe though)

Works

Way cheaper here than at my local shop for the exact same thing. Very flexible and easy to install, only question is the thickness of the wiring, about as thick as ten year old ofc 4 gauge wire I have laying around. I guess they make the jacket thicker these days to have the same appearance as wire of old, regardless it works.
