About the EFX PA4BX Wiring Kit
Get the right wire for your amp
Get the right wire for your amp
The PA4BX wiring kit from EFX will supply your car amplifier with the wiring necessary for receiving its signal and powering up. The 4-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 3 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 450 to 1100 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.

Crutchfield customer from Fayetteville, NC on 7/9/2019
Nice kit, they even included a grommet to feed the power wire thru a metal surface so the cable doesn't get damaged. Doesn't include speaker wire tho. That's the reason for 4 stars.
Pros: Nice kit. Seems to be good quality

Beau from Sharon Springs, KS on 7/22/2017
Kit was great, except RCA cables fit loosely on the amp and head unit. I had to bend and tape them to ensure they would stay secure. Everything else was top notch.
Pros: Great kit other than RCA connections.

Great Wiring Kit
Pedro from El Paso, TX on 5/4/2017
This was my first Amp Installation. I looked over many wiring kits and was blown away by the amount of kits available. This one was confirmed to work by CJ, a Crutchfield Advisor. The box was very small, but had a 17' of Power Cable, Remote Turn On Wire and RCA Signal Cables. The Ground Wire was the shortest, at 2'. For the install in my 98 K1500 Extended Cab Truck, I ran the 4 Gauge Power Cable through the Passenger Side, through the Firewall and along the panels on the Passenger Side behing the rear seat. I was able to use the included Wire Protector Loom to cover from the end of the Fuse Block to about halfway in the Passenger Door. I did have to buy more Wire Protector Loom, but I got it covered and wrapped in Electrical Tape to seal it all the way back. I routed the Remote Turn On Wire and the RCA Signal Cables through the Driver Side, also putting them in Wire Protector Loom and wrapping it in Electrical Tape. There was plenty of wire to reach from the Pioneer Stereo to behind the Rear Seat and to the Amp. The Fuse Block is attached, and after some figuring out, it was easy to put in the fuse and secure it. I did have to drill the opening on the Power Cable where it attaches to the Battery, as it was too small to fit on my Battery Post. The kit came with Wire Ties, Butt Connectors, Screws and other items, which I did not use but were handy to have. This is a great wiring kit and I would definitely recommend it!
Pros: 17' Length of Power Cable, Remote Turn On Wire, and RCA Signal Cables, 2" Ground Cable with Three Mounting Points, Incorporated Fuse Block. Includes Wire Ties, Fuse, Butt Connectors, and other Handy Items for the Installation.
Cons: None

EFX PA4BX Wiring Kit
Crutchfield customer from Bordentown, NJ on 5/3/2017
This kit was handy when installing my amp, it contained everything that I needed. The reason for three stars is the fact that the short section of power cable that connects to the battery pulled out of the fuse holder during installation. The set screw wasn't tightened correctly. I'm just glad that it happened when it did, and not at some later point during use. I also felt that the included wire loom was on the thin side
Pros: Included everything I needed
Cons: Poor assembly Wire loom on the cheap side

Dave from San Antonio, TX on 6/8/2016
Heavy duty gauge power and ground wires. RCA cable are quality (they don't get twisted up!) No engine noise or other outside electrical interference that destroy your signal path. I ran the power wires on the opposite side of the vehicle to the RCA input wires to ensure no interference.
Pros: Heavy duty Easy to install Don't tangle

Main cable too short for trunk
Robert from Plano, TX on 5/10/2016
Nice kit. Good quality. I ran the power from the battery, under the fender trim and through an existing firewall hole behind the engine. This extra routing to hide the wires left me 2.5 feet short of making it to the custom amp shelf under the parcel shelf in the trunk. Probably my fault for not measuring before, but I figured since it was a kit, it would be long enough- so I was lazy. The remote wire for the amp was plenty long, but I didn't have to run that all the way to the battery (duh).
Pros: Makes for an easy install. Everything you need, including a firewall grommet.
Cons: Power wire was too short for my needs.

Great overall kit. Quality pieces. More than enough 4ga to run from the Front left at the battery along the drivers side under the carpet to under the middle rear seat. Had approx 2-3 ft left.
Pros: Well put together kit
Cons: Minor but the negative could've been another foot longer for more (better) grounding options.

Works fine
No problems using this kit. Recommended by an advisor. Price was right. Installed in a 2014 Accord 4 door. In my opinion the power lead wasn't very long. Ran it to the trunk and mounted to the back of the rear seat. only 8"-12" left. Not much wiggle room. The lead for the ground was very short as well.

No foresight in design
Mike from New York on 8/25/2015
Looked alright out of the box, and it came with a set of RCA cables, which I needed so I figured it was a good deal. Not so. First of all, the ground terminal on the less than generous length of ground wire does not fit on any bolts you might find in/near the trunk of a car. I should not have to drill new holes in my chassis when there are plenty of perfectly good grounds in the area. Pressed for time I shoved it as far behind one of these as I could for now. Finish up everything and go to install the fuse in the block and reconnect the battery. Once the fuse is installed there is no way to tighten the screw one side slides into. It looks like there was supposed to be a hole there that wasn't drilled. It's pitch black out at this point and don't have time. Backed the screw out just enough to wiggle the fuse under and held it down by tightening the end cap of the block. Whatever. Went to connect the +battery, discovered the hole in the end was too small to fit over the screw on my 75 series battery, which aren't exactly uncommon. Was forced to drill it out only to find the connector wasn't long enough to allow clearance between the car's +12v and the battery terminal. I ended up having to use the 8 gauge wire from my old Kicker kit that ran from the fuse block to the battery. Now I can't safely push my equipment because of the bottleneck. Nothing I've ever had from the Scosche brand has been quality or a proper fit. Not worth the savings. Ruined install of an $1,100 system.
Pros: - Came with RCA cables. - It's a pair of 4 gauge wires.
Cons: - No thought put into the designs of the connectors. - Poor quality control. - Does not fit a common 75 series battery.

Needs a longer ground
NCLK from North Carolina on 7/25/2015
Bought this to hook up my bass and amp in a boat - the advisor suggested this wire kit - problem is on a boat - you will likely need a longer ground if you mount the amp away from the engine and closer to the head unit. This kit is for a car - they need to mention this as I lost a week of my install time waiting for a 17' ground cable.
Pros: Good quality cable
Cons: Needs a longer ground for boat use.

Good install kit
KCHahn from Colorado on 5/5/2015
Good kit, that made installing a Kenwood amplifier fairly easy.
Pros: Plenty of Blue(hot) power cable to get from battery to back of extra cab Ranger. RCA cables plenty long also, as was the Auto On connection wire, between the Radio and the Amplifier.
Cons: Ground cable too short, depending on mounting location. Extra fuse would have been handy, since I blew mine by accident. Didn't use many of the other parts. Ran my cable through hood release cable plug, so I didn't need the grommet.

Pros: Copper, good length of wire for positive, rca and remote.
Cons: Be careful, it's easy to strip the connections on the fuse block, very short ground cable, and the zip ties included break if you try to really tighten them down.

short ground cable
jorge from 99301 on 2/27/2015
Overall first impressions on this kit is ok. It came in a plain white box not very impressive. Quality doesn't seem bad but I couldnt find out if it was 100% oxygen free copper which for the price it should be. The ground cable is way short. I guess i should've read more carefully but for the price that seems a little stingy imo. Other than thay no complains.

wiring kit review 4g
Bosco from Sacramento California on 10/20/2014
I upgraded the free 8g wiring kit to the 4g kit when I purchased the clutch field amp. Customer service was superb as always and they prorated the upgrade for me. As for the kit, the 4G wire is great, but one little thing, hence the one star minus is the 2ch patch rca, the 8g kit has gold plated connector and the 4G kit only comes with, assuming nickel rca connectors. Make no sense since the 4G is 30 dollars more. But I ended up using that for my sub so it's all good.
Pros: Price
Cons: Rca patch cable

More details on the EFX PA4BX Wiring Kit
Product Research
Features
Compatibility: The PA4BX kit is designed for amplifiers with fuse ratings up to 100 amps.
Kit Contents: This amp wiring kit includes the following:
- Power/Ground/Remote wire: The power/ground wires use OFC
