GS Power 12 AWG (American Wire Gauge) Flexible OFC Zip Cord Speaker Cable for Car Stereo Amplifier Remote Automotive Trailer Harness Hookup Wiring | 25 ft Red & 25 Black Bonded – Pure Copper

Sound improvement/quality on power cords. More stranded pure OFC copper. Great value.

Got this on prime day for a killer deal. Havent had a chance to use it yet but seems to be pure copper. Not cca.

Its pretty good stuff. It is NOT tinned and its heavy enough to be 100% copper. I believe its a PVC jacket

Excellent product As described.

Works great. Used it to wire 15-18 Amp ham radios in my truck. Thick enough with true stranded copper inside

Merchandise matched the description - product arrived a day before expected - product high quality

Great !!!!!!! for my light bar. No over heating and fuse blowing easy to handle , Super durable.. also added extra pod lights all home runs , highly recommended..

all copper, great value, very flexable.

Used it to install lights on my Ford ranger and this came in handy. Very well insulated wire. Would recommend for any light installation.

Conductor is 2.65 mm meaning it is closer to 10Awg wire. 12Awg is spec’d at 2.05 mm. Overall diameter with jacket is 3.94mm… insulation thicknesses is therefore .645 mm. Looks to be copper not CCA. No printing on jacket or UL markings.
