GearIT Speaker Wire Audio Cable CCA 2x4mm≤ (30.48 Meters - Black) Copper Clad Aluminum - Great for Hi-Fi Home Theater and Car Speakers - 12 Gauge AWG, 100 Feet

the wire did make a difference to the sound of my speakers

Quality of the cable is very excellent.... and economic also ....👍

This GearIT 12AWG speaker wire may seem like a great deal, but BEWARE: it is made of copper-clad aluminum (CCA), not pure copper. That means it doesn’t conduct electricity as efficiently as pure copper wires. For comparison, this 12 AWG aluminum cable has about the same resistance as a 14 AWG pure copper cable. This makes it less ideal for long distances or high-quality speaker setups, where lower resistance is crucial for performance. Aluminum wires are also less durable and prone to oxidation, potentially reducing their lifespan in certain environments.On the positive side, the cable is flexible enough for standard installations, though it might not hold up as well to repeated bending (not usually an issue for domestic sound systems). One feature I appreciated is the marked spool, which lets you see how much cable is left—very handy for installations.Overall, this is a decent budget option for casual or short-run setups, but if you’re looking for optimal sound quality, especially over longer distances, you might want to invest in pure copper cables.
