Review: Good wire to use for speakers - Worked and did the job as intended had no issues with the product. I've been using it for about 6 months now to power the speakers in my car and they are all rated for 300 watts without any issues so far. The insulation has held up and even though I was not using oxygen-free copper it is still handling the required load well.
Review: Excellent wire! - This wire is very soft and flexible. Many strands and tinned nicely. A perfect upgrade for my power wheel wires that keep melting. These have been running for months in exterior environment without any issues.

## Questions & Answers

**Q: Is it resistent to UV light (i.e.,exterior use)?**
A: Silicone is highly UV resistant.
Howver, single conductor wire should not be used "in the open" if the voltage on the conductors is hazardous, approx 24 volts ac or 60 volts dc.  There is a need for mechanical protection of insulation (like at least the jacket of a cable, if not some sort of conduit) as well as basic insulation.

**Q: Can someone confirm me what over diameter means? is it the insulator + wire diameter?**
A: The standardized method of measuring the thickness of a cable (American Wire Gauge or AWG) was established in 1857 in the United States. This form of measuring cable thickness is used specifically for electrically conductive wire. Note that the diameter of the cable does not include the outer insulation - just the conducting wire on the inside.

**Q: Does 18awg mean that it’s for 18 volts? i need it to extend the black and red cords for 12v speakers**
A: In response to a previous answer, the smaller the gauge number, the bigger it is in diameter and the more amps it can handle. Each AWG size is rated for a certain amperage at a certain voltage. So to start, you should find out what voltage your system is running at. Then, look up a table of the maximum amperage at that found voltage. Finally, select a wire gauge that is over that limit. The further you go, the cooler it will stay and the safer it should be. 

For example, say we have a motor that uses 35 amps at 12 volts. According to a cart I looked up, at 12 volts AWG 12 gauge wire can handle 41 amps while AWG 14 is only rated for 32. Therefore, we should select AWG 12 gauge or higher to handle the load without burning up.

There is a whole science and you can really get into the math of it but this is a good place to start. If you want to be safe, you can always go a bit higher and sacrifice a little extra cash for peace of mind. I hope this helps

**Q: Will this work in auto use? I'm replacing broken wires in a lighting harness on a pick up truck.**
A: yes,auto use for lighting harness on a truck,this wire  Bear Current 5A

### ⭐⭐⭐⭐⭐ Good wire to use for speakers
*by J***. on February 14, 2026*

### ⭐⭐⭐⭐⭐ Excellent wire!
*by D***D on October 31, 2025*

This wire is very soft and flexible. Many strands and tinned nicely. A perfect upgrade for my power wheel wires that keep melting. These have been running for months in exterior environment without any issues.

### ⭐⭐⭐⭐⭐ Wires, perfect for simple electrical needs
*by P***T on March 16, 2025*

These 12 gauge wires are perfect to have around if you are doing simple electrical work like installing light switches or light fixers. The 6 colors allow for easy matching if color coded wires already exist in the structure. But if you are working in an older structure where wires are covered by cloth, these color choices are ideal to help distinguish line types running through a junction box or conduit. In addition, the softness of the wire covering makes the wires easier to manipulate and place in tight spaces. Using a wire stripping tool was very easy. Finally, the filaments are easy to twist and insert in holes or wrap around existing wires. Great value. Great product.
