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 copper wire. You get 25 feet of StreetWires 14-gauge Ultra Cable speaker wire in this package — plenty for most installations.

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 speakers to a moderately powerful amp. For a secure, good-looking installation, use StreetWires speaker wire terminals, too. Warranty: 1 year.

25ft was barley enough

Written By Josh, michigan on Thursday, June 13, 2013

Crutchfield Customer Review (What's this?)

Very thick outer wrap has its pros and cons,yes its hard to get aroung tight bends or underneath panels,but if you need the extra protection on your wires,say for running through a firewall,near heated objects or around your power cable,this is the wire i would suggest for you.The wire looks good and is quite heavy.witch im my experince, heavier componets USUALLY perform better.Anyway,as far as sound quality goes,i changed alot of stuff all at the same time so i couldnt tell you if they chaged the whole sound.what i can tell you is they dont sound bad at all.

Pros: thick outer wrap gives you peace of mind near hot items or near power cable

Cons: difficult to work with because its so thick.compare to 8 gauge powerr cable

Great heavy duty product,although hard to work with. The thick outer covering makes it difficult to run the wire.

Nice but pricey

Very nice speaker wire but really think about these as they are $1.00 per foot.

This is a good, quality wire with nothing negative to be said about it. I just wish I had measured more carefully and ordered more as I ran out towards the end of my install!

Great Wire

Great wire and love the protective shield. Great for running into doors if not able to run through rubber boot.

Great wires

Written By Mark, PA on Saturday, August 16, 2008

I replaced all the existing stock speaker wires in my car, the Streetwires make the task very simple. The wire was easy to work with. It enhanced the quality of the music coming through my audio system.

Crutchfield Customer Review (What's this?)

This is by far the best audio speaker wire that I have came across. I just installed two Infinity Kappa 6x9's (rear deck) and Infinity Kappa 6.5 (front doors) to an alpine amp. This wire was perfect for the job. It is very durable and easy to work with. It's definitely worth the money.

Works as promised.

This wire was easy to run and the thick outer protective jacket is a plus. The inner copper wire is very pliable, and is of good quality.
