Absolutely performs as advertised. Exquisite quality and a nice price too. I'm running 2,000 watts through two Rockford fosgate amps and DSP. With a big three upgrade also. This is the best OFC wire. I'm running this for ground and power and my sound is much improved. I would recommend this for serious music lovers who like power. PURE POWER

Good wire. Actually the length advertised. Appears legit. Worked great.

Its real 8 Gauge OFC at an excellent price. I purchased it to replace a cheap boss CCA "8 gauge" (more like 10 AWG). I took some comparison pics. Black wire is InstallGear. It works great, no V drop. Is good for 500W RMS, maybe a bit more. It flexible and strips/crimps well. Will definitely buy again.

Great amp wire to run in general, used in a 22 Civic. Clean power and amp has been running solid since installation. Spend the extra money and buy pure copper when installing amps in your cars.

Flexible, solders easily, insulation seems good and has good electrical properties. Made ground cables for the car, cut, crimped and soldered the ends on for max power transfer without heat. The insulation seems pretty good and withstands a good amount of heat. The cable itself can transfer some power without problem. Very easy to route anywhere I needed it to go. As good as it gets for heavier cables that look decent and like OEM. The only thing I will say that is a slight negative is I dont think this is the cable itself seems a bit thin for 4 gauge. The copper calble seems to be less of a diameter than what I would expect 4 gauge but in all fairness I did not actually measure it. I would buy it again, it does work well, it does the job I need it to do and looks good. I can recommend this for projects that need doing.

0 gauge (1/0) has an OD of 8.25 according to AWG. I measured 10.2 mm with a little caliper squish on the exposed copper between the outside jacket and a round terminal I slid the wire into.. So that I could verify the diameter is as advertised. Since the wire is a coil of coils of coils, the outside diameter is not a circle. This could be why I measured larger than the standard. Either way, it explains what savvy buyers want to know.. That you're getting ample diameter for the marketed spec. The coil upon coil upon coil of copper along with the polyurethane jacket is exceptionally flexible and feels great. It was a pleasure to work with. I made a weekend out of it. I measured exactly 25' for each the black and the red. Funny how the price varied between colors :-) I crimped ring terminals with vice grips against a bolt to push into one side of the terminals. the terminal and wire interface felt unusually rigid in a good way. All the strands crush into a solid terminal really well. Reviews I saw before buying this were as dumb as expecting the sun not to fade their wire. If you ask for features more than what these have, I think you're asking too much. As a side note, I also found that running a ground the length of your run/ car along with your positive cable has extreme benefits! Your chassis can be a ground, but it's unreliable and forces current through/ near/ around all components in it's path.. And when ran together, electric fields by the current in the positive cable, are neutralized by being in such close proximity (zip-tied) to it's counterpart. That's right, reduced/ no stereo whine.

100% QUALITY.

amazing copper power wire used for my amp

Parfait !!! vrais cuivre

Excellent quality wire at a great price! Full OFC and not CCA. Jacket/casing is soft and very flexible. Nicely packaged and works well for car audio installs. 10/10 would buy again.

Excelente cable, muy recomendable.

Exactly as advertised. Quality cable, all copper wire. Used for a long run from battery to DC-to-DC charging setup in my camper van.
