Used this Install Gear 1/0 gauge wire for my car audio setup and it works great. The cable is thick, flexible, and easy to run through tight spots. Feels durable, and the insulation is tough but still easy to strip. Good power flow and no issues with voltage drop. Overall, really solid wire for the price — would definitely buy again.

Have a project on a Ford F-350 Crew Cab with a 6.4L diesel, this is the perfect length to run wire from the driver's side battery all the way to my tool box at the back of the cab for my Vevor air compressor. I will be buying this again for auxiliary jump ports at the front and rear of the truck as well. Good quality wire, and plastic jacketing.

Bought the 4 ga size & is accurate sizing/thickness & good quality copper. This item is more opaque, not solid in color. Easy to strip, flexable & good quality insulation.

Perfect for the wiring changes that I needed to make for my RV batteries, changing to lithium and adding additional batteries and solar capabilities.

Im running a Soundqubed HDS3.1 15" rated 2400WMax/1200WRMS. I was originally pushing it w/an Orion Cobalt 2500.1D that's rated 1200RMS@1ohm which is how it's wired. I started w/ KnuKoncepts Kollosus OFC 4ga wire which, although I'm a fan of KnuKoncepts, it seemed like my Sub was under powered. After a clamp test I found I was, AT BEST, getting low 700's. I figured that, w/Cobalt bein Orion's budget brand of Amps, that my 2500.1D was most likely over rated but it had an internal Fuse rating of 120amps which take fuse rating X's voltage output, so conservatively let's say 12V, which my car always makes 13.9v when on, but at 12v that still comes to 1440 so I figured it must be under powered from lack of sufficient gauged 12v+ & gnd wire. Due to insufficient funds I made due w/ what I had but after 7mos my 2500.1D stopped workin correctly, began kickin in & out of protection mode & sounded terrible whenever it wasn't in protection mode. I discovered this meant it was shot so I stepped up to the Cobalt 3500.1D but after just a month this Amp began the same problem. So I decided to try this 1/0 wire in hopes that this would stop the failures I kept having w/ my Cobalts, even though it's CCA rather than OFC & I've always been a believer in OFC or nothing, but anyone who knows wire prices knows the significant difference in price for 20' of 1/0ga OFC compared to CCA wire. I finally got it installed, haven't got it hooked to a properly sized Amp for my sub since my Cobalts both shot craps already but the Power Acoustiks RZR Amp I'm temporarily using, til I can afford a larger amp again, seems to be happy with the power it's receiving from this wire. It's very flexible for 1/0ga CCA wire I was pleasantly surprised, made running it through my engine compartment & firewall easier than I had expected it to be. Although I haven't measured officially it appears to be legit or very close to correct gauge. It's wrapped in thick insulation but doesn't seem to be a(use insulation to make up for insufficient wire) situation to make 2gauge appear to be 1/0ga. It's definitely worth every penny of what it costs considering what you get & what you pay. Happy enough to buy again definitely regardless of it not being OFC. Thanks for the great wire @ an amazing price!

Easy to work with, cut, strip, crimp on lugs. Used for parallel Class 31 battery set of four batteries. Short runs of cable are operating fully, haven't checked operating current.

Very nice product. Silicon insulation means it is very flexible, not stiff like most wire. I was able to easily run it around my engine bay from the battery connection at the starter to a relay I installed for the fuse box, neatly tucking away most of it from view.
