    The following review is for XKIT42, which is a part of the bundle you are viewing.

    The wire is so thick for quality sound production and yet so flexible. I didn't do my own install but the installer guy asked me about the kit and seemed to like the ease it offered

    Top quality kit. The power cable is very easy to bend, and the fuse block is well built. My only complaint is the oddball fuse

    NVX XKIT42

    The following review is for XKIT42, which is a part of the bundle you are viewing.

    This is the perfect kit for anything around 1000 watts RMS. I have it hooked to a NVX JAD1200.1, and it is perfect. I literally have nothing bad to say about this kit. Every wire is true to gauge and it comes with plenty of wire, even 40ft of speaker wire! The RCA works great and the wires are strong and flexible. It'd be nice if it was a little cheaper, but it's definitely worth it. NVX makes some of the best, high quality wires and instillation equipment.

    great product!!!!

    The following review is for XKIT42, which is a part of the bundle you are viewing.

    this has to be the best connection kit I have ever used.. everything was flawlessly constructed and everything you need is in the kit, remember you get what you pay for... I am using this in a small suv that has no carpet but herculiner throughout and I need pure copper for corrosion resistance.. could be cheaper I guess..

    Best wiring overall

    The following review is for XKIT42, which is a part of the bundle you are viewing.

    when i received this and opened it up i was amazed when i saw how a 4ga. wire could look so much like 0ga. and bend so easily. the speaker wire is so thick that you would not believe that it is speaker wire. the wires also make your music sound so much clearer than any other wiring can. all the components are the best in quality.

    Not your average amp kit.

    The following review is for XKIT42, which is a part of the bundle you are viewing.

    If you're picking up a bad*ss amp, why wouldn't you pick up a PROPER wiring kit ?!
    I've previously used NVX Power/Ground wire for a BIG 3 Upgrade install, and was blown away by the Quality of the wire. High Strand, True To Spec, Super Flexible, Very Durable, and Conducts Very Well. Same can be said for the Speaker Wire and RCAs. I wish NVX made a kit with their higher end RCA cables, but the ones with this kit definitely get the job done. The fact that the Power/Ground come Crimped and Shrink Wrapped really save on install time, and the flex wrap on the Power Wire makes the install look Very professional. I ended up using the other goodies (ties and connectors) for various other things, but its pretty cool that it comes with the kit.

    The following review is for XKIT42, which is a part of the bundle you are viewing.

    Great true 4 gauge wire kit. Both power/ground cables are flexible easy to work with, rca calbe is great. This kit comes with everything you need for an amp install. I will be using NVX amp kits for now on future installs.
