About the Crutchfield CKD4

Deliver the power your amps deserve

Crutchfield's 4-gauge dual amplifier wiring kit contains the wire and hardware necessary to supply power to two amplifiers safely, efficiently, and economically. A fused distribution block helps keep your installation neat, and protects each amp from dangerous short circuits. This wiring kit does not include RCA patch cables or speaker wire. You may need to purchase those items separately, in order to complete your installation.

You may need to purchase those items separately, in order to complete your installation.

Power ratings and amp efficiency

Most amplifiers come in two distinct "Classes" of technology with different efficiencies and power wire size requirements. This Crutchfield wiring kit was designed to accommodate the energy demands of two Class AB amplifiers with a combined total output of up to 700 watts RMS — a 50 watts x 4 speaker amplifier plus a 500-watt sub amp, for example. For Class D amps, the kit will work with up to 1,100 watts RMS total output — a 75 watts x 4 amp plus a 750-watt sub amp, for example.

CTA-2015 Compliant

Crutchfield wire

Crutchfield wire is made of oxygen-free copper, with no impurities that could raise its resistance to a signal's flow or add interference. Crutchfield wire meets all Consumer Technology Association (CTA-2015) standards for size, resistance, and insulation quality.

Crutchfield customer from Lloyd Harbor, NY on 6/24/2019

Verified employee purchase (What's this?)

Everything you need to install an amp and a powered subwoofer.

Pros: Cheaper than buying separately

Cons: 1. Could have used an extra foot of length in the secondary power and ground wires 2. Would have preferred more standard fuses 3. The thick gauge of the wire made connection to the subwoofer difficult. Could have used some sort of adapter

Quality kit; make sure it's what you need.

Shaun from Centennial, CO on 2/10/2019

Verified employee purchase (What's this?)

This kit is great if you are installing a sub and and amp in close proximity. But if you're putting the amp under the drivers seat and the sub in the back, it doesn't work out quite as well. The 4G wire has a quality housing and 17 feet would reach from the battery back to the cargo area in our 4Runner. However, we put the amp under the drivers seat and the sub in the back, so had to split the 4G at the front seat; there's not enough 8G wire to run to the amp and the sub. So we picked up some additional 6G wire to run back to the sub. Ended up not using most of the 4G wire. Also, with our setup, the grounds can't be connected using the supplied wire and block, so grounded the amp and sub separately and didn't use the block. Also, the plastic covers on the fuse blocks don't stay on very well, so have added some tape and hoping they'll stay.

So so kit - check with installer before buying

franc23 from Northborough, MA on 12/7/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Not that great a saving if you're not going to install it yourself. I had mine installed by car audio specialists and they ended up having to use additional parts - which in turn cost some more money. Might as well buy the full kit from them. Further, got two different advice from Crutchfield specialists when ordering on the actual install kit i needed - for the same speaker/woofer/amp components. Which was interesting to say the least, but I was in a hurry and went ahead with the second Crutchfield rep's suggestion.

Good dual amp installation kit

Rick from Smithfield, VA on 8/31/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

My only reason for not giving 5 stars is I feel the 4ga ground wire is too short. While I understand 3 ft will work for most car audio installations, the kit would also work for RV, off road or motorcycle cycle installation if the length was 6 ft like the 8 ga power and ground. I had to buy a longer 4 ga ground so it would reach directly to the battery vice frame.

Pros: Comes with distribution blocks and fuses needed.

Cons: 4 ga ground wire too short for some applications

Nice, tight package

Antonio from Salida, CA on 8/11/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Overall high quality wire kit. Only issue was the distribution block came with a fuse rated higher than what was required of my mono amp. Also, the package states that it comes with two additional ring connectors but they were missing in the bag. Although I did have to call Crutchfield to ameliorate this, they responded swiftly with great customer service.

Pros: Comes with mostly everything you need to install two amps

Cons: Fuses may not be right match for your amps. Package contents inaccurate.

I just opened the kit and noticed it's missing 2 pcs 4-gauge ring terminals and 4 pcs black wire ties. I have not measured lengths of wire. Fuses come loaded in holders. Seems like a quality kit, but needs to be labeled correctly.

Pros: Seems good but haven't installed yet.

Cons: Missing 2 loose ring terminals and 4 wire ties.

All came as described. Wire was easy to work with and seems to be of high quality. Fuse holders though seemed a little cheap. The cover is easily knocked off and the the attachment points for the distribution blocks are a bit flimsy.

Just what you need to install 2 mid size amps. Everything in it seams to be of good quality. The fuse holders are nice, but I notice the covers are easy to knock off. That's the reason I dropped this rating to 4 stars. I used a wire wrap around each of the fuse holders to insure the covers stay in place.

Pros: Good price to install 2 mid size amps.

Cons: Fuse covers pop off easily.

Good quality but overpriced

Mike from Pennsylvania on 11/11/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

Though this kit is a very high quality it lacks vital components. For the price of this kit it does not include enough. It should have the RCA cables and speaker wire at least. The price point for a kit like this is a rediculasly price when all it includes is heavy Gage wire and fuse boxes. You can find the same quality kit for less money and it includes more. I should've read into it a little more before purchasing. 2 stars for price and lack of all the components that you will need for any install you do.

Pros: High quality

Cons: High price and missing cables.

Great kit

David from Albuquerque, NM on 9/10/2017

Verified customer (What's this?)
Verified employee purchase (What's this?)

The components of this kit are very high quality. The power cable is flexible and very easy to work with. I like that it comes with a fused distribution block, but the distribution block is where my one and only complaint lies. It only has 8 ga outputs instead of being sleeved for 4 or 8 ga. Luckily the metal is soft enough (aluminum I believe) that I was able to use a 5/16" drill bit to enlarge one side to accept the gauge wire. In short, this is a great wiring kit for powering two amps so it gets 5 stars still since I was able to modify the distribution block without any negative consequences.

Pros: -Easy to work with and install two amps. -High quality copper wire

Cons: Distribution block only has 8 gauge outputs. I feel it should be sleeved so it can accept either 4 or 8 gauge wire.

Quality Kit

Ronnie from Greencastle Indiana on 6/25/2017

Verified employee purchase (What's this?)

I opened the kit expecting the 4 gage wire to be stiff from being bound with twist ties. To my surprise it was as limp as cooked spaghetti making easy to work with. The fuse blocks are thick walled plastic,very solid and snapped together firmly plus they're attractive for showing your gear.

Pros: All things needed to run power to two amps in trunk in one kit. Well made product.

Cons: None. After doing a project of any type and completing it I do not wish to go back and trouble shoot to find out what went wrong. Get it right the first time. This kit is solid quality with eye appeal.

Jorge from St. Cloud, FL on 2/2/2017

Good kit but for a couple of parts, the butt connectors are brittle, would have prefer to see the heat shrink butt connector type. The hard plastic grommet supplied for the 4 GA cord does not provide a good seal, would have prefer to see a heavy duty grommet or a strain relief. Other than that it is a great kit.

Pros: All you need in one box

Cons: None

Great deal going on this wiring kit w/purchase of amp plus, I may change the system in the near future and add another amp. Getting a good deal on it made the purchase a no-brainer. [ A  Jul 04, 2017 ]

Decided on 4AWG even though Crutchfield recommended 8AWG because I wanted to future proof the wiring in the vehicle. If i ever go bigger on the amp/sub, I don't have to rewire the car. I went with Crutchfield's brand as my 1st time trying them out. You can always return the product while in the package if its not what you paid for. I said "why not?" [ Vincent  Dec 04, 2016 ]

Q
In an article about choosing the wiring on here it says to double the amp's watts because of the efficiency loss. Does the maximum watts on this product already assume this? so if I had a 400 watt amp and 250 watt amp would this kit work? if i have to double that it would be over the 1100 watt figure.

Yes that will work make sure you ground your amps first and in the same spot . That's called common ground

TThis kit works. I have a 4-channel amp (800watt) and a mono amp (500watt). This is the kit you need for the power you choose.

Q
I'm new to these kind of things with subs and stuff but does this connect the radio to the amp then to the subs or do I have to get a separate wiring harnes to connect the amp to the radio?

No. The wiring comes with this system.This is all you need.
[ VERONICA R  Mar 21, 2017 ]

If one amp, your all good. Multiple amps need extra rca jacks to plug into the amplifiers. I installed 2 amps, one mono amp, one 4-channel amp. I had to buy 2 more rca jacks. This gives me more control to remain the music. Although, you can run the single rca then use line splitters to connect multiple amps, that leaves the amps as the only control over the sound.
[ Stephen  Mar 20, 2017 ]

This wiring kit is awesome but it only brings power from your battery to your amps. You run the heavy gauge wire from the battery to a splitter and you can power 2 amps. Then the 2nd splitter is used to ground both amps. You will most likely need separate RCA cables (or wires if you are feeding from the radio speaker outputs) to connect from the head unit to the anps.
[ Mark  Mar 20, 2017 ]

This kit is for connecting two separate amps to the car's battery and ground. The kit also has a wire that connects to the radio that signals the amp to turn on when the radio is on. You will need additional RCA cables to connect the audio signal from the radio to the amps.
[ Doug  Mar 19, 2017 ]

This kit has a ~16gauge blue wire that is connected to most after market head units (radio) as the "remote wire". This would tell the amp the radio has been turned on, and the amp would use thst signal tp turn itself on. This lit is used to provide adequate power to the amp, which needs a good ground source (black wire) connect to a screw so that contact can be made with bare metal. The red wire in this kit is connected to the + battery terminal with the provided fuse ~12in from the battery, the other end goes to the + terminal on the amp. The actual sound signal connection between the amp and the head unit is done with speaker wire (high level) or RCA cables with on cable pair per speaker. Crutchfield has great tutorials and diagrams on their site with more details than I can provide here.

Hi - This kit is just for power. The red wire will connect to your car battery, run through the firewall, and back to your amp(s), which are usually mounted in the trunk. The black wire is for ground. You will ground your amp(s) to your car chassis. You will need a separate wire harness for the back of your stereo along with RCA cables that will run from the back of your stereo to your amps. You will also need speaker wire to run from your amps to your speakers (usually 16-18 gauge). Hope this helps.
[ gabe  Mar 19, 2017 ]

I think this will answer your question. In short, it connects your battery to amplifier via fat power cord. There is also a thin wire that connects your radio to the on/off remote on your amp. It doesn't include the "rca" cables, which connect your radio to your amp.
[ BRADEN  Mar 19, 2017 ]

This kit powers two amps. You'll need to add a set of RCA interconnects, either 2 or 4 channel or both depending on your set up. Now your subs plug into your sub/mono amp which you'll need speaker wire for those....
[ DAMON  Mar 19, 2017 ]

This kit is just for powering an amp. Comes with power and ground wire and fuse blocks. You'll need rca cables to connect an aftermarket head unit unless you're using your stock head unit.
