    I would give this wiring set ⭐️⭐️⭐️ out of 5 it has everything you need. But the quality is not the best. But if you want a cheap wire set with everything you need this is a good one . Shipping was a little slow. But I live in the middle of nowhere.

    Great price genuine 4ga. Wire

    The kit has everything you need the only issue I found with it is that the power and ground wire are a little shorter than I would have liked but still worked in a 2009 crown victoria so a really long car anyway but I've seen reviews that said it wasn't thick as advertised but it is 4 gauge wire plenty thick enough for what I used it on and big enough for larger amps aswell the only other bad is it is copper coated aluminum wire as opposed to just being pure copper wire but works great my 1000 watt amp hits good and this kit is a great value I had priced the same thing at best buy it was over$ 100 definitely this is the way to go

    Use your own terminals

    Good wire but the terminals are very weak and made of cheap metal and don’t crimp down well or hold well they bend and snap very easy. Not very good. Not a huge thing but just go to Home Depot or somewhere and buy your own terminals. For power and ground and all the others there thin aluminum

    great wiring kit for your amps except....

    As an engineer, i am very particular about sizes and current carrying capacity. I ordered this kit because based on my amp and sub wattage, I needed 4 gauge. Well, this is smaller, like closer to 6AWG (larger numbers are smaller wires). I needed 4, not smaller. Other than that, it's good quality.

    SoundBox 4Ga. Amp kit

    It's a very decent quality for the price, the wire seems to be a true 4 ga. and the kit has everything you will need for a amp install.. The only con I have is the speaker wire should be a larger gauge for a 2000 watt amp kit, it seems to be 16 gage wire and should at least be 10-12 gauge..

    Love it! Potential for 5 stars

    I am very pleased and shocked at the quality of this product! The power wire is "True" 4 Gauge and very heavy duty, also the ground wire is surprisingly heavy duty as well. 13 feet of power, RC jacks, remote wire and plenty of speaker wire. The kit also comes with a nice plastic power wire cover. the only issue it had was the fuse was cheap and broke within a week. but that was ok, I went and bought a Heavy Duty Gold 80 amp. which works very well. I would have gave it 5 stars if it wasn't for the fuse. I do recommend it though
