Very high quality wire is great for automotive use
Size: 25FT, Style: 8AWG
This is really good quality wire. The insulation is thick, it is super flexible and very finely stranded. In fact the strands are so fine that you really should be using ferrules to terminate the wire. Without a ferrule, it would be very easy to have a stray strand extend to another terminal, and the strands are so fine that you may not even see it if you have old eyes like me.
I used this wire to run from my battery to a fuse, and then to an amplifier inside my vehicle. The wire is so flexible that it may be difficult to push it through the grommets in the firewall of a vehicle. I wound up taping it to a coat hanger, and pushing it through, which was an effective workaround. The insulation is also a bit grippy, so it may be a good idea to apply a lubricant to the grommet, so you don't wind up pulling the whole grommet out of the hole while pulling the wire.
If I needed more wire, I would certainly pick up more of this for my next project.

Good as it Gets
Size: 50FT, Style: 8AWG, Size: 50FT, Style: 8AWG
This is excellent wire I've been doing solar set ups for about 2 years now and this is as good as any I have used or seen. The Silicone insulation is super supple - it can easily be bent into quarter (25 cent) size loops. It is a true 8AWG super fine stranded tinned copper cable. It doesn't appear to be listed - but the cable is stamped every couple inches with 200* C and 8AWG. I'll forgo the listing - I know this stuff is good wire - and the only inspection I have to pass is my own. I ordered the 50 foot Red, 50 foot black. It is selling now for about 90 bucks. 90 cents a foot – pretty good deal for this wire.

The 8 Gauge Silicone Wire kit (50ft red and 50ft black) is an absolute game-changer for anyone working with RC cars, boats, drones, or any high-performance electronics! The wire is made from 1650 ultra-fine tinned copper strands that offer incredible flexibility and bendability. This makes it perfect for tight spaces or projects that require a lot of maneuverability.
The silicone insulation is top-notch—it's soft, durable, and incredibly heat-resistant, handling temperatures from -60°C to +200°C without issue. I’ve used it in various applications, and it’s been flawless in both scorching heat and freezing cold conditions. Plus, the tinned copper core ensures excellent conductivity and low resistance, which means maximum efficiency for your devices.
Whether you're wiring RC planes, boats, cars, or working on home appliances or motors, this wire has you covered. It’s also eco-friendly and non-toxic, which is a huge plus if you care about the environment.
The kit includes 50ft of red and black wire, which is more than enough for most projects. If you're looking for durable, flexible, and high-performance wiring that can withstand extreme conditions, this silicone wire is the way to go!
Highly recommend it for anyone in need of reliable, long-lasting power solutions for their electronic projects!

Great easy plugs and even better value
Size: 6 pairs
Great plugs and amazing value for the money. Easy to use and tighten and the screw cover works wonderfully. Even comes with a couple extra screws in case you lose one. The sound is better than what I had and I used 14 gauge wire. Plugs were perfect, not too tight at all. I could see having to push for new posts but they are snug and didn't take too much force to put in. 10/10
