Get the right wire for your amp

The PA8BX wiring kit from EFX will supply your car amplifier with the wiring necessary for receiving its signal and powering up. The 8-gauge power and ground cables ensure that your amp gets all the power it needs to play music at its full potential. The ground cable features EFX's Ultimate Ground Terminal, which attaches to your vehicle's chassis by way of 2 self-tapping screws (included) to make sure you get a tight physical and electrically secure ground connection.

This wiring kit works with amplifiers with between about 250 to 450 watts RMS of total output power. Please check your amplifier's installation instructions to confirm the proper size wire to use. The kit includes a stereo RCA patch cable, remote turn-on lead, in-line fuseholder, fuse, and an assortment of connectors and hardware to help with your amp's installation.

This wiring kit does not include speaker wires. You will need to purchase those separately, in order to complete your amplifier installation. This kit includes patch cables for a 2-channel or mono amp — you'll need to add cables for multi-channel amps.

Product Highlights:

  • amplifier wiring kit with power, ground, and audio connections
  • 17-foot blue 8-gauge power cable
  • 2-foot black 8-gauge ground cable with Ultimate Ground Terminal
  • 17-foot blue remote turn-on lead
  • 17-foot twisted pair RCA patch cable
  • 60-amp fuse and in-line fuse holder
  • 6 feet of flex loom
  • assorted mounting screws, crimp-on connectors, and wire ties
  • warranty: 90 days (no warranty on fuses)

Wiring kit

Written By Aaron, Austin, Texas on Sunday, April 26, 2015

Crutchfield Customer Review (What's this?)

It wires your amp to your battery. Includes one RCA cable, so if you're wiring a 4 channel amp, you'll need another RCA cable. There are no speaker wires included, but speaker wire is not expensive, so that shouldn't be a problem. Installing the main fuse in the holder was tricky, I don't remember how I did it, but I know it wasn't straight forward.

Great wiring kit

What a great wiring kit for the price. You just can't beat it!

Pros: Quality-Price-Looks

Cons: no cons

Crutchfield Customer Review (What's this?)

Power wire and ground are nice, fit and work great. The only hiccup is the funky fuse. Next is the RCA, I had to swap it, it was creating a ton of feed back in the system to the point where you couldn't stand listening or having radio on. I ran a test set of RCA's and worked great, so I yanked the one in the kit and tossed it in the trash.

Pros: Good Power and Ground

Cons: RCA is junk

Written By Rc1960, California on Wednesday, April 08, 2015

I bought this kit for it's value it has the same setup as the kicker brand minus the speaker wire which I already had and the price was after all $50.00 less but the quality and value are there even though it's a house brand kit according to one of the tech's I spoke to prior to making my decision to purchase this kit and glad I did.

Pros: ease of use and quality of product included in kit.

This wiring kit was recommended by the Crutchfield advisor, and it was everything I needed to install my new amp. It was nice to get everything I needed in one package and not getting into the installation only to find out I was missing something.

Pros: Everything needed for amp installation

Cons: None

Over all this was a great kit but it forgot to include a 60 amp fuse that was needed. So I had to go out and purchase one. Besides that it has everything I needed to hook up my subs

Crutchfield Customer Review (What's this?)

Everything needed for the connection. Could probably get all of this for less money, but my time is not free. I value efficiency and this kit has all you need.

Pros: All in one.

Cons: Ground cable a bit short. Limited options to connect to chassis.

Everything you need in one package to wire your amp. Good quality and great price!

Straight Forward

Written By Knight, Chapel Hill, NC on Saturday, January 17, 2015

Crutchfield Customer Review (What's this?)

Went in easy enough. However, I had to buy an additional grounding cable because the provided cable was only 2 feet long. Not sure why they don't provide ample length here and allow you to customize the placement in your car or truck. Otherwise works great. Be prepared to rip your car apart to run the necessary wires.

Pros: Everything is included.

Cons: Short Grounding Cable

Scared at first

Written By jeff-SA, San Antonio, Texas on Friday, January 16, 2015

Crutchfield Customer Review (What's this?)

Although my son and I were able to install speakers and a new receiver, I was apprehensive about installing the amplifier for a sub. I really didn't want to poke a hole through the firewall, and didn't know how we were going to get the cables all the way from the front of vehicle to the back. I really should have known Crutchfield would have a great installation manual. The wiring kit came with EVERYTHING I needed, including very clear instructions on how to use it. We actually completed the job in less than an hour. It works great! Thanks Crutchfield.

Pros: Very easy install Includes instructions All required parts included

Cons: Cover for lead in engine compartment could be a bit more substantial.

Great Wiring Kit!

Written By Julio C, Puerto Rico on Wednesday, January 14, 2015

Crutchfield Customer Review (What's this?)

Great wiring kit! very complete, with everything you need to wire your pre-amplified sub. Delivers great audio signal. Great, clean, deep bass sound. I used it to wire my Rockford Fosgate Punch P300-10 to my new Pioneer AVH-X3600BHS receiver on my 2012 Honda Fit Sport. A+

Pros: Very complete wiring kit, you won't need anything else. Delivers great audio signal.

Cons: none

This package had everything you need to install the amp. Cables are plenty long. However, there could use a second wire to power the speaker. Ground was fine for me but could be a problem for some as it was only 2 ft long.

Pros: Free!

Cons: None

Good but cheap

Written By jlhovis, North Carolina on Monday, December 01, 2014

Crutchfield Customer Review (What's this?)

This came free with the amp i ordered. While it saved me money, this kit is not a very high quality wiring kit. It gets the job done, no need for anything else, and it saved me money so it was worth it.

Good wiring kit

Written By Chris, Virginia Beach, Virginia on Friday, November 28, 2014

Crutchfield Customer Review (What's this?)

Good wiring kit, came with everything but speaker wire but I had some laying around so that was no big deal.

Pros: Connections were nice and tight, came with everything you need.

Cons: Ground wire is only 2 feet long, definitely limited the option of where I could ground it too.

Can't beat the price

Written By johnluk, irmo, sc on Wednesday, November 19, 2014

Crutchfield Customer Review (What's this?)

Well, even at retail price this wiring kit is more than adequate. It was plenty of wire, all the needed connectors, grommets , ties and a good fuse holder. The ground wire is just under 2 feet, which can be limited, however most amplifier companies recommend a ground as short as possible. I would order again if I ever expand my system.

Pros: One kit is all you need.

Cons: ground wire could be longer....

Great deal in truth, everything you need for the wiring besides the speaker wire.

Pros: Cheap, more than enough power wire.

Cons: Could use longer wire for ground, no speaker wire.
