GS Power 12 Gauge Wire (12 AWG) - 100 Foot, Pure Copper, Stranded Electrical Wiring for Speaker, Automotive, Trailer, Stereo and Home Theater Applications - Red/Black

I dont know about the wire, I only bought it to have on hand. Seems OK. Good price for 100 Feet.

Worked for my needs

Wire comes nicely wrapped on the plastic spool. Great for RV 12-volt accessory electrical work.

In my photo, Audiopipe is on the left and GS Power is on the right. Un-stripped they are about the same size. Stripped with the same tool you can see the considerable difference in how much wire there is. The Audiopipe insulation is really thick, and if thats what matters (not how much current it can handle) then that is the wire for you. What many sellers DONT say is that they are selling CCA (Copper Clad Aluminum), rather than pure copper wire. Its hard to see in the photo, but each strand of the Audiopipe wire really is a different color on the inside. You can solder it due to the copper coating, but its not copper and that means it will expand more when heated so Id avoid clamp connections. The bottom line is that if you really need 12 AWG and you dont want aluminum wire you should pay the extra price for GS Power. They are honest about what they sell.

Real stranded copper I stead of the cheap tinned copper.

I use this wire for building battery packs and power supplies. It is high quality and decently priced. The only drawback is when I am soldering with high heat the pvc jacket will melt easier than other wire I have used. This doesnt matter to me because I always use shrink tubing after soldering the wires. Without shrink tubing, the results may be a little less than professional looking.

wire works just fine

I used this wire for solar-powered lights in the garage and is working fine!

OK, I did not use this wire for speakers. I have vehicles in the driveway but the pandemic limits my use of vehicles. So I bought Battery Minders to keep them topped off. The problem is that the vehicles are not in the garage and the Battery Minders cant be left outside. This low impedance wire solved that problem. It seems tough enough to stand California weather (note: no snow!) and it is bright enough that the mailman wont trip on it...

I’m happy with the quality of this wire spool so far. I have now idea about the wires insulation and how it would hold up to heat but I’m not using it in a hot environment. It seems true to the correct gauge and I’ve bought the 12 and 10 Ga spools.
