    • Best wire for big 3
Color: 1 Red, 2 Black
Review Image by Sean N.
This wire is worth every penny. It's some of the thickest 1/0 awg avaible. I almost bought skyhigh but decided to go GP this time. The only downside is that the wire isn't as flexible as skyhigh but it has thicker insulation which is very important when you're running wires underneath your hood. It's also heat resistant up to 225 degrees , oil, gas, cut, tear and acid resistant. I've notice a big difference in the performance of my kicker kxa1600.1 amplifier. If you plan on doing this make sure you fuse the positive wire from battery to alternator. Also make sure your battery is unhooked before you even start this task. GP is what you need under your hood. Tip: The big 3 consist of 1 Battery + to alternator +. 2. Battery - (ground) to chassis 3. Engine block ground to chassis. 4. Bonus: alternator ground to battery - It's now the big 4 upgrade Do not replace wire, just add to the existing wire. ... show more

    • Provides more wire length than other kits
Color: 1 Orange, 2 Black
This kit went in very easy and quickly. It is put together nicely and I like the double jacket on the wire. It appears to be quality wire and have a quality jacket. I received plenty of wire to complete the install. Engine to battery negative, frame to battery negative, and alternator positive to the distribution center main connection. I had a 0 gauge amp kit with 20 foot of wire to install, so ran the positive to the distribution center and then another positive from the distribution center to the battery. This was most convenient for me. I had purchased battery clamps that included two 0 gauge connections and two 4-8 gauge connections each. I really needed 3 0 gauge connections in the positive to make this work correctly. Not a fault of the kit, just an oversite of my own. I would buy this kit again and may purchase another when I get ready to install my winch kit on my F-450. ... show more

    • Long enough, and sturdy
Color: 1 Green, 2 Black
More than enough cable to get the job done. I had enough left over to run another batt neg to ground. Cable is sturdy and well insulated but pliable enough to move where needed. The lugs and heat shrink fit well and the heat shrink shrinks properly without burning or distortion even using open flame. 10/10 recommend if you’re doing the Big 3 Upgrade ... show more

    • It's a pretty decent wire but there is better options for the money.
Color: 1 Green, 2 Black
Review Image by Jason H.
Good wire but there is better for around the same price. I thought the wire would be thicker, but it's the double sheath surround that gives it the oversized appearance. It's not as nice as my Skyhigh OFC big 3 kit. The green is dull and I would've went with the red and black had I known that. All in all, it's a okay kit. It's definitely going to work for my stereo but for the money, there are better options that will benefit you down the line. ... show more

    • TOP OF THE LINE OFC AUDIO WIRE
Color: 1 Red, 2 Black
Right away from the feel in your hand you can tell you are about to install some wire that is a step above the rest. Very flexible and not too large as 0 guage wire. Excellent choice with the shielding as well, this is the wire to use you wont be disappointed. Not as thick as sky high which is good for applications and very well insulated/protected. ... show more

Got some weight to it and for dang sure does the job 💪🏾 Full tilt holds my voltage at 13.8-14.4 steady. I only have a 1200 rms amp but still does great. Will be ordering another kit soon (if the wife lets me)
