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)
  • Our 60-day money-back guarantee

great kit

Written By foxyota, washington on Saturday, May 30, 2015

Crutchfield Customer Review (What's this?)

The only thing they can improve on is sending more than one style or different sizes of connectors for the amp.

Pros: Everything you need to install an aftermarket amp.

This kit made wiring the amp a breeze.

Pros: Ease of use.

Exactly what I wanted

Written By Hayden, San Luis Obispo, CA on Tuesday, May 19, 2015

Crutchfield Customer Review (What's this?)

Super easy to set up. The instructions were very clear and videos were available on their website to help make sense of things. Put it together myself with no prior experience in 3 hours and the sound is perfect.

Pros: Worked exactly how it should.

Cons: None

quality product

Written By Ian, Wausau, WI on Monday, May 18, 2015

Crutchfield Customer Review (What's this?)

Kit works wonderfully well... Was originally concerned because I have always used larger wire than needed to amp installs but when Crutchfield told me this was what I needed for my amp I went with it. Came with everything I could have needed!

Pros: Quality product Came with all needed connectors/parts Separate remote wire and rca cables so both power wires can be run together and signal can be run elsewhere for less interference

Cons: Would have preferred the screws for the fuse to be self drilling Would have been nice to not have to top the insides out of my car but for installing an amp/sub it can't be helped

More than adequate

EFX PA8BX Wiring Kit Reviews

Written By Tom M., Maryland on Tuesday, May 12, 2015

Crutchfield Customer Review (What's this?)

When I read "amp wiring kit" I expected everything I needed to attach the amp. Kit only includes 1 RCA cable. It also does not include any speaker wiring. Ended up having to stop install and run around town to get what was missing. Would have paid more to have a 'complete' kit.

Also...I ended up having to pull head unit out again since once channel of the RCA cable was bad. Had to completely replace the RCA cable.

Pros: Power lead setup is great. High gauge....good fuse setup.

Cons: - RCA cable was bad - No second RCA cable for 4 channel installation - No speaker wire

Everything I needed

Written By mrdctaylor, Texas on Sunday, May 10, 2015

Crutchfield Customer Review (What's this?)

This was everything I needed. Period. I purchased a Sound Ordnance mono amp and this was recommended along with it. It was everything I needed to install the amp in the back of my son's Hyundai Santa Fe. It was nice having everything. The wire was of good quality and everything went together smoothly.

Pros: Relatively inexpensive. Everything you need in one box. Everything seems like good quality.

Cons: The only negative is that the fuses used by the power cable are not that common. You will probably have to find an car stereo installation place to buy them if you need them. Fortunately, I bought some "just in case" and have not needed them so far.

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

RCA IS BAD

Written By 79Camaro454, Medina, OH on Wednesday, April 22, 2015

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

Great value for a house brand !

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.

Cons: None

Crutchfield Customer Review (What's this?)

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

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!

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!

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.

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....
