Our take on the EFX 8-gauge Amplifier Wiring Kit

by Ken Nail

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 8-gauge power and ground cables, a twisted-pair stereo RCA audio 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 60 amperes.

Quick impressions from the Lab

Comment by Jude Director, Digital Imaging,

Perfect kit!

Written by Jude, Director, Digital Imaging, on 7/10/2014 9:28:00 AM

My son just purchased a newer car, a 2002 Pontiac Sunfire and the sound system it came with was, well, awful. We sat down together and planned a system and since he was on a budget we decided we would go with our house brand Sound Ordnance for most of it, and we are not disappointed. We installed the P65-C in the rear deck using the SA69 6X9 adapter. We then installed the P-40 in the front doors with fabricated brackets we made from the 12x12 sheet of ABS #1208900903 and then used the Dynamat #15410415 to seal it all up and add sound deadening to the doors. We chose the JVC KD-R950BT for the Bluetooth and the generous power the internal amplifier has, plus the abundant color choices made it easy to match the red backlighting in the Pontiac. We needed bass so we used the Sound Ordnance B-24 and the Rockford Fosgate #575P500X1B we had from his previous vehicle and connected it using the EFX 8 gauge wiring kit #142PA8. We spent a Sunday working on this project and have to say it exceeded my expectations on sound. It sounds clear, the bass hits as hard as you want and the total price was well within his budget. This is a great system and it was also a great day spent with my son.

EFX 8-gauge wiring kit

Written By JerrodA, Glasgow, KY on Sunday, July 27, 2014
Crutchfield Customer Review (What's this?)
 
Seems like a decent wiring kit, especially since I got it free with the amp I purchased from Crutchfield. It does have a unique fuse which may be hard to find if I need one in the future, but it comes with an extra one and I got my equipment hooked up without blowing it so I'm not too worried about it. The power wire is only 17' long. My old one was 20' and this new one was almost too short by the time I routed it from the battery to the drivers side of the truck, into the cab to behind the seats and then to the passenger seat where my amp is located. I took the long way around but couldn't find a good place to bring it thru on passenger side. I have an 09 reg cab silverado.
Pros:
Free with Sound ordnance amp purchase
Cons:
only 17' long special fuse that is not common

Exactly what I needed!

Written By Paul, Denver, CO on Sunday, July 20, 2014
Crutchfield Customer Review (What's this?)
 
This amp wiring kit was a great price and had everything needed. I did supply a small amount of speaker wire to run from the amp to the speakers, and that is fine as this was not sold as an amp and speaker wiring kit.
Pros:
Great quality Plenty of wire length for my 2010 Scion Xb Easy install if you know what you are doing.
Cons:
The kit comes with a small bag filled with wiring ends and fuses, but the instructions do not mention when and where to use these. Not a big deal as most should be able to figure it out, but for the novice do it yourself-er a little more information would help. Along these same lines, this is a wiring kit that is being hooked to an electrical source. Including some basic information on how to properly ground and test the install as you go, would help insure safety, and avoid novice mistakes.

JT

Written By JT, Rockford, IL on Monday, June 30, 2014
 
Wire is great and everything you need is there. Here's the problem, the fusible link that comes with the system has a couple of cheap blade connectors to hold the fuse in place. I would get drop out now and again at louder volumes and the amp is buried, so it's hard to see if it was a protect issue or what. I tore the entire back out to get to the amp and see that the amp in not powered. wtf? I checked all the grounds and that only left the hot side. After RMAing the amp one time and having the same issue with the new amp I finially got to the fuse and when I pulled it, it came out very easy, too easy. I took a pair of pliers and crimped the blade connectors down a bit and installed it and it was fixed... lot of messing around because they cheaped out on the fusible link.
Pros:
Wire and cable are good
Cons:
Bad fusible link allows intermittent connection. Make sure you have a solid connection for the fuse-able link!!!

Better Than Expected

Written By Levi H, Ohio on Friday, April 18, 2014
Crutchfield Customer Review (What's this?)
 
I used this to install a 4 channel amp in a 1998 Grand Prix Sedan, it works like it should. I have another amp install kit (also 8 gauge) by Boss, and I'm going to replace the Boss wiring with this as soon as I get the money. I think this is true 8 gauge wire, unlike my Boss wire.
Pros:
True 8 gauge, good and thick RCA's
Cons:
Power wire could be a little longer. I have a Grand Prix and it was just barely long enough to make it to the top of the trunk

Crutchfield Customer Review (What's this?)
 
I've been in car audio for 16 years now. I don't do it professionally, but I've installed my far share of systems over the years. This kit comes with everything you need for an install and all the kits I've seen it has the best cables you can get for the price of other kits.
Pros:
Twisted pair RCA cables Two fuses ANL style which I find to be alot better than the round style fuses. plent of remote wire Ends alread crimpt on for power and ground wires. Overall for a cheap price compared to name brand kits It's just as good.
Cons:
Power wire maybe a little short for some vehicles. I think it should have 20ft instead of 17.5ft Ground wire is a little to long RCA's could fit a little snugger around the rca jack.

Great cables for the price. I would give 4.5 stars but had to round up only because one of the connectors on the 17-ft Stereo RCA interconnect cable broke off during the cable run.
Pros:
Splitloom for under the hood, Grommet, and extra fuse
Cons:
17-ft Stereo RCA interconnect cable seems to be a little on the cheap side. One of the connectors broke off the cable during the cable run. I had to use speaker wires from the stereo instead.

Written By S. Kusen, Brookhaven, PA on Wednesday, September 04, 2013
Crutchfield Customer Review (What's this?)
 
8ga wire was what I needed to wire up, so no problems there. Everything fit on my amp, but I could see where the limited number of connectors provided for the power, ground, and remote wires might need different connectors to fit on the set screws (don't know that for a fact, though). Power wire might also be a bit short for other vehicles, but it reached from battery to the trunk with about 3-5 inches to spare in my 2013 Civic LX.
Pros:
Easy to connect
Cons:
power wire could be longer for larger vehicles

Everything you need, with the exception of speaker wire. Quality cables. Wiring diagram on back is helpful if you need it. The type of fuse it comes with is a little annoying as you can see from the picture below the power cable. It's not the type where you can just plug in or pull out. It's held down with screws which is interesting.
Pros:
Quality wires and ring terminals already in place. Little work to do for you.
Cons:
No speaker wire.

Great Kit, Great Value

Written By Boscorilious, Laveen, AZ on Sunday, April 28, 2013
Crutchfield Customer Review (What's this?)
 
First amp install and I used this kit. Couldn't be happier with the quality of the wires. I was little disappointed in the size and quality of the split loom they provided. Very cheap and impacted the 5-stars I would have given if it wasn't for that. At this point in time, no issues or concerns.
Pros:
All wires (ground, power, remote) were long enough and good quality. Although the wire sheath was strong, I still used aftermarket split loom to run the entire distance between connections for added protections.
Cons:
The included split loom by EFX is junk, run down to your local automotive store and grab 20-30' of 3/8". It'll get the job done.

Barely long enough

Written By DanW, Davison, MI on Saturday, January 12, 2013
Crutchfield Customer Review (What's this?)
 
These were the perfect cable set. However, when I went to pull the power line, it was just barely long enough to make the whole route from the battery terminal through the firewall, along next to the seat, through the back wall, and to the amp. My care is a tiny Honda Civic, so I was surprised when I was so limited in cable length. I would hate to think if I was pulling the same cable through a full sized car. When I finally reached the trunk, I had so little left, I only had one option for placing the amp. I had to put it right next to where the cable entered the trunk on the floor. I had hopes of side mounting the amp, but that wasn't possible. I would recommend they add another foot or 2 to the cable so that people have options. This kit is best suited for a truck installation.
Pros:
- top quality cables remain pliable even in the cold of winter - cable guard makes for a professional look - included fuse fits a professional installation
Cons:
- limited main battery cable length

Great entry/mid level kit

Written By TKD-KING, Vancouver, BC on Thursday, August 30, 2012
Crutchfield Customer Review (What's this?)
 
The EFX 8-gauge Amp Kit is a great entry/mid level amp kit. Includes everything you'll need to get going where as some kits don't come with RCA cables etc. 8G is enough for any simple setups, and my JL Amp called for 8G - no need for 6 or 4. The fuses are pretty rare tho, so you'll need an ebay account to order me if you start blowing them.
Pros:
Comes with everything! Price is great
Cons:
Fuses are unique. RCA's are braided so cannot be split for mono amps.

Outstanding Product, but Way Overpriced

Written By Caleb M., Jacksonville, AL on Monday, June 18, 2012
Crutchfield Customer Review (What's this?)
 
I was hoping to score this as a freebie with my large purchase from Crutchfield, but sadly, I did not. I spent the money and purchased this kit. It came with everything I needed. The quality was outstanding and saved me a couple of hours trying to scrounge all the pieces that came with this from my house and various hardware stores in my area. The quality of the wires and the split covers are great, the zip ties and extra fuses will come in handy. Overall, a great purchase to save some time and stress.
Pros:
Good quality, Nice appearance, time saver
Cons:
Price

This is very good 8gauge wire. Im using to power my 1,000 watt 2 channel amp and it seems to be doing fine after two weeks. My only complaint is that this way over priced. I didn't originally choose this, but my crutchfield adviser advised me to get this. i would personally get one from another website but hey, at least here you get customer service and a 1 year warranty. :)

Does the Job

Written By DCLAguy11, Arlington, VA on Thursday, May 17, 2012
Crutchfield Customer Review (What's this?)
 
This kit gets the job done. It includes more than what you need to install an amplifier. I used it to install the Sound Ordinance 8PT amp and had more than enough wires, etc to make it all work. It's a must if you are installing the amp yourself.
Pros:
Everything is included.
Cons:
Does not come with speaker wire but I would recommend using the RCAs whenever possible.

Everything you need to connect an amplifier to your head unit is included. The only thing you'll need to supply is the connectors for your speaker wires.
Pros:
Heavy duty 8 Gauge wiring and solid construction.
Cons:
17' was barely long enough to connect the positive lead from my battery to the trunk.

OK I got this for free after buying the 8inch powerd sound ordance sub and it did what it was suposed to.. Great for a low powered system. Comes with everything you need, and 1 extra fuse bonus!! $50 I think is a little high if you to buy it outright. For free you cant beat it!!

Pretty good product

Written By blaketg, Punta Gorda, FL on Saturday, April 21, 2012
Crutchfield Customer Review (What's this?)
 
This product came with everything you need and more. Would definitely recommend. The only drawback was that the power wire was barely long enough. I have a crew cab 09 Silverado, and I had to run the wire to the opposite side of the vehicle from the battery to get through the firewall. By doing that, I barely had enough length to get the wire to the amp location.

Great Amp Wiring Kit

All of the cables are heavy duty and bulky, which I personally like. All cables were plenty long enough, no shortages in wire. Easy to hide also, if you know what you are doing. Not bad for the price at all.

This is a very complete kit of quality components. The wires are of excellent quality and plenty of length to reach the subwoofer I installed under the back seat of my 2006 Toyota Tundra access cab. I would have rated 5 stars but the spade lugs for the ground and power cables could have been a little beefier.
Pros:
Everything I needed and more. Good quality.
Cons:
The spade lugs for the ground and power cable could have been a little beefier.

Great wiring kit

Written By DanJ, San Diego, CA on Tuesday, February 07, 2012
Crutchfield Customer Review (What's this?)
 
The kit has everything needed. The main power wire was long enough for wiring to my powered subwoofer to back seat of my 2007 Honda Ridgeline. The Amp wires were also long enough to go from head unit to the powered sub as well. the connectors were sized correctly for the wiring as well. Though the connectors are VERY rigid- (not necessarily a bad thing, but you have to CRIMP very hard). I actually hadn't crimped hard enough on the ground and kept wondering why my amp would power up, then immediately turn off- after checking connections I realized the ground was 'barely' crimped.
Pros:
Long wires/fuses/ etc.
Cons:
connectors require a HARD crimping (not necessarily a bad thing if you know ahead of time)

The Sound Ordnance B-8P was my first purchase from Crutchfield so I didn't know what to expect from the free wiring kit. Usually I toss the wiring kits and make my own but this one was a nice surprise. The quality was as good as anything I could pick up locally.

Good build quality. Had 2 extra feet of cable after getting the cables to the trunk ('02 Subaru Legacy sedan).

Perfect wiring solution!

Written By Yodaforce, Western NC on Wednesday, February 01, 2012
Crutchfield Customer Review (What's this?)
 
I have never understood why alot of people thought you had to spend big bucks on an amplifier wiring kit. Componants of these kits are fairly general and not alot of real differences. Cable is cable. The fuse junction and RCA patch cables are really the only thing that you do not want to skimp on. This kit was perfect for my amplifier install, with enough cable to reach the entire length of my vehicle, and with the braided patch cables and covered fuse block, did just what I expected. It simplified the installation, and where it is visible on the vehicle (engine compartment and truck at the amp) it looks good.
Pros:
Looks, performance, PRICE!
