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.
Everything worked perfectly and was exactly what I needed
I used this for my first install. Everything I needed was there, plus a few extra little components that I didn't end up needing/using. Used it to run a 2000W 5-Channel amp with a 600W sub (speakers pending), and everything works/sounds amazing.
Package has everything you need. Quality cables.
Nice quality kit, plenty of length and the wire is of nice quality! Made my install easy!
Pros: Good quality wire.
Cons: Needs to give a little more length on the ground wire I came up short considering I added a capacitor before the amp.
Perfect install kit. Everything need to do a proper installbof an amplifier
Pros: Everything included to install
Cons: You gotta find one cause I cant
I bought this product and had my hardware installed at an local car stereo shop. It had all but one item included the RCA plug-in wires.
Pros: Quality product no problems with installation.
Cons: No RCA plug-in wires.
Good: Copper, ok length of wire for positive, rca and remote.
Not so Good: easy to strip the connections on the fuse block
This kit is good. All cables are good quality. It came up short on the power wire though in an 09 Impala. Other than that, good quality.
Pros: Wood quality cables
Cons: Power cord came up short
Great quality product. I found cheaper but after looking at this one when it arrived it's definitely best deal for $$$
Pros: Great quality!
Cons: Would have liked a few more 4 gauge connectors to add for a capacitor etc.
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.
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.
Everything needed was included besides speaker wire, but that is relatively cheap and available on the site.
Pros: RCA wires
Cons: No speaker wires
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.
The only issue i had was the connection to my battery didn't work more of chevys problem then to do with the kit
Pros: All of it! Great sound no transfer or issues!
Nice heavy wire
Everything worked great and seems to function flawlessly
Pros: All wire is quality and was easy to install
Cons: No fuse was in the box but they sent me two for free and the guy was very nice and helpful also the ground wire was shorter than I would have liked
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.
Great kit and half off with the amp I ordered.
Pros: Great kit!
Cons: None so far.
Great all around wire kit for the money, again easy to run and nice fuse set up
Pros: Comes with everything needed to power a amplifier
crutchfield recommended this so i I ordered this to go with m r 1200-1d amp. i have no issues with it so far and it was easy to install myself
Pros: easy install
Exactly as described, came with connectors and everything you need to wire your amplifier.
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.
Very nice kit!! High quality
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.
Great quality at a great price. Crutchfield comes through again!
Pros: Plenty of accessories included in this kit Power wire was the perfect length for my 07 double cab tacoma Instructions help during install
Cons: Ground wire worked for my situation but could be short in other situations. Power cable fuse housing could have a better design that is more waterproof. (Thinking about adding silicone to mine to waterproof)
Good option if you are clueless, like me.
Pros: As advertised.
Cons: The firewall grommet is worthless, if you need it. The grounding cable is short, so make sure of your placement first.
This kit has everything you need to hook up your high power amp.
Pros: The cables are very flexable and has a very high strand count.
Cons: I wish they would give you a spare fuse in the kit.
very nice price and good quality.
Pros: sturdy good grade cables and connector
Cons: could use better connetors and they should have wanred you need a bigger crimp kit to set
Great wiring kit so far. Easy to install and get through the firewall.
Pros: Not to much to say just yet cuz I've only been able to use them for not even a week yet.
Cons: Annoys me how short the ground wire is.
Had everything I needed to hook up my amp
Pros: includes everything needed...instructions make hook up a snap
Cons: for my installation, it would have been nice to have had two or three extra feet of power and ground wire length
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.
Cons: Rca patch cable
I loved this kit. The reviews are spot on!!
Pros: Comes with everything you need.
Compatibility: The PA4BX kit is designed for amplifiers with fuse ratings up to 100 amps.

Lee helped me select this amplifier kit because it had all the options needed for my amplifier installation. Thanks Crutchfield! Lee's Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=79 [ Alexander Feb 03, 2016 ]
Need it [ Lukas Feb 02, 2016 ]
The reviews ranked the performance of this kit among others that cost up to twice as much. Great deal. [ Sonny K. Dec 15, 2015 ]
I believe so but cannot be sure. I would call into Crutchfield and have them chase [ TRACY Jul 01, 2015 ]
Yes, I am using two of these wiring kits, one for my JL JX500/1D amp that powers my JL TW1 10" sub and one for my JX360/2 amp that powers my JL C2650. I've had them installed for over a year now and I am very happy with this product, it comes with everything you need for the install. I switched out the fuses to T-SPEC V8 Mini-ANL Fuses because the kit comes with 100A fuse and I wanted to go with something closer to what the amp was rated for. [ THOMAS Jul 01, 2015 ]
yes and I have installed two of these wiring kits in my car one for the amp that powers my sub and one for the amp that powers my speakers. I've had them installed for over a year now and had no issues. very happy with the performance of this prodict. [ THOMAS Jul 01, 2015 ]
Yes it does. [ Edward Jun 30, 2015 ]
I am not sure. I bought this product in August of last year. It is a great product and have had no issues with it. I am running an Infinity 4 channel amp on it for my 4 Infinity door speakers. I love buying from Crutchfield because they offer good customer support. I would contact tech support through chat or phone. They can easily answer thus question. I am sorry I could not be more helpful [ Matthew Mar 02, 2015 ]
The power and ground cable is copper. Not sure about the rca cables. [ HENRY Mar 02, 2015 ]
Gosh I have no clue. But it has functioned fine [ justin Mar 02, 2015 ]
I do not have an answer to what type of copper this is but I do know that this wiring kit is amazing. Extremely easy to wire and very reliable. I ran into zero issues with this product. I am sorry I could not answer your original question. I do believe it is oxygen free. [ Brendan Mar 02, 2015 ]
