Don't let low-grade speaker wire be the weak link in your car audio system. Get every ounce of juice from your amplifier to your speakers with StreetWires Ultra Cable twisted-construction tinned copper wire.

The installation-friendly, non-gripping wire jacket is flexible yet rugged. The lower the gauge, the thicker the wire — we recommend 14-gauge wire if you're connecting a subwoofer or component speakers to a moderately powerful amp. Warranty: 1 year.

great wire

Written By Brian, San Antonio, Texas on Sunday, January 14, 2007

This is great wire. Easy to use. Invest in a good wire stripper and a razor blade. Take your time. Easy to pull using a fish tape. Great sound.

Good quality wire. Outside tubing is hard to remove but totally worth it. I eventually just bought a auto stripper.

Good wire & easy to pull. Removing the outer covering is a pain though.

Crutchfield Customer Review (What's this?)

I just installed a Profile amp that puts out 100 Watts RMS and 200 Watts Peak. They are connected to Polk db 690's and they pack a punch. I am no professional, but I cannot detect any noise from these wires. The sheath can be a pain during installation, but it pays off as a protective cover and with it's "Wow" factor. They handle the above mentioned set up with ease, but installation can suck.

Crutchfield Customer Review (What's this?)

Great product, good price. High quality tinned copper wire, unlike similar aluminum wires I have seen elsewhere. External sheath is tough and rugged which protects the wire, but sometimes must be removed where space is very tight (through protective boots in the doors) and removal requires a lot of care to protect the wires. Also makes stripping the wire a bit more difficult because it must be removed. A bit stiffer than untwisted, unsheathed wire, but still plenty flexible for most apps. Remove sheath for more flexibility. Looks nice, too! I'm using it to run power from my twin RF 451S (#575451S) amps to my JBL Power P923 6x9s and JBL Power P625 6-1/2s (both are titanium composite design).
