Our take on the EFX 4-gauge Amplifier Wiring Kit

This wiring kit does not include speaker wire, so you'll need to purchase that separately to complete your amp installation. This kit includes patch cables for a 2-channel or mono amp — you'll need to add cables for multi-channel amps.

Make sure you enjoy the full potential of your new amplifier by hooking it up with quality power and signal connections.

This wiring kit from EFX includes 4-gauge power and ground cables, 17' Stereo RCA interconnect cable, space-saving mini wafer fuse holder and fuse, and all the accessories you'll need to connect your new amp. Just add whatever speaker wire you need, and you're ready to go. Designed for amplifiers with a fuse rating of up to 100 amperes.

Highlights:

  • amplifier wiring kit with power, ground, and audio connections
  • 17-foot blue 4-gauge power cable
  • 4-foot silver 4-gauge ground cable
  • 17-foot blue remote turn-on lead
  • 17' Stereo RCA interconnect cable
  • 100-amp mini wafer in-line fuse and fuse holder
  • 6 feet of flex loom
  • assorted crimp-on connectors and wire ties
  • warranty: 1 year (no warranty on fuses)
  • Our 60-day money-back guarantee

Great kit for the price. I run a install shop and have not found a better value on the market. The zip ties in the kit are worthless. I was able to crimp the connectors with an average set of pliers but you better have strong hands they are heavy made. Thats exactly what you should want though. Make sure you buy speaker wire and zip ties. You also want to possibly order another fuse when you purchase your kit I have not seen the type of fuse in this kit available at any local parts store. The wires are blue and spruce up any engine compartment. It comes with ample amount of wiring, conectors, remote wire pretty much everything you need but what I listed above. Dont buy lower grade wires than this even for small watt aplilcations. You will either blow fuses or overheat your amp everytime you turn the volume up for extended periods. Even if you can find a kit cheaper with the same quality I would still recommend spending the few extra bucks and buy from crutchfeild their customer support is top notch If they cant answer your questions your probally shouldnt even try it.

Awesome kit, used it on my Honda S2000 and I love it. The only con I can say about the kit is the 6 plastic wire ties break easily. But, thats no big deal in my opinion, and other than that this amp kit is definitely worth the price and I highly recommend.

Great Wiring kit for small car like mine. If you have a larger car you may be safer with a little longer power cable.

I'm blown away by the ease of use of this kit. Since this was my first install I was hesitant at first, but Mike @ Crutchfield gave me the pep talk that I needed. It comes pretty much everything you need including wire ties and misc. parts needed for install. Very nice quality and well put together.

Cool Blue

Written By Chris, Wichita, Ks. on Sunday, January 07, 2007
 
Great wire for a 1200 watt amplifier, and 2-800 watt 12 inch subwoofers in a bandpass box. Much better than the 200 watt max amp wiring kit that I had connected to the amp at first. Kept blowing fuses. Wonder why. Funny. The connectors to this thick 4 gauge wire, although quite tough. I've found that a good set of vise grips will flatten them against the wires.
