    4 gauge Merica wire

    Posted by Keith Webber on Aug 18th 2021

    Been using GP Audio for a year now bought a Ford Expedition with basic factory radio so totally new system from start to finish decided to try GP Audio just from pictures of this wire it looks well like some very nice wire esterichally they all pretty much do but this wire is what it was no bulls—t audio pure oxygen free copper it stands out just with that no tinned which I like as well but eye Candy is what people see and the rubber jacket is tough not as pliable or easy to use but the reason is your wire is well protected from what ever, and it’s got a second coating under the first for heat protection as well and the copper strands are exactly that pure copper again no bs it doesn’t bend or make installing any easier like other companies wires do but really it bends easier is not a decision maker here any ways build quality attention to detail and protecting my investment and feeding my equipment with 100% pure copper my amps love it as much as I do and the solid distinctive colors just add to the overall package, don’t wait or think u will try someone else’s brand this wire is the real deal no BS says so on the label and if that’s your slogan then your product needs to be just that, and it is, GP Audio FTW!

    Best GP Wire Ever

    Posted by NightWulf on May 19th 2019

    I Have Ordered 0 Gauge OFC Wire In The Past And I Have To Say GP Wire Is Worth Every Penny. I Needed 4 Gauge For My 4 Channel Amplifier Just To Make Sure The Power Is Running To The Amp Smoothly. I Did Have 8 Gauge OFC But Its Kinda Small, So This 4 Gauge OFC Wire Is A Awesome Upgrade To Have.
