Best Amp Wiring Kit Buying Guide & FAQ
There are several things you will need to consider before buying an amp wiring kit. Should you choose copper wire or copper coated aluminium? What size do you need? Can you mix gauges? Below we will talk about the things you need to consider before buying an amp kit and answer your most frequently asked questions.
What to Consider When Buying an Amp Wiring Kit
There are several things you will need to consider before buying the best amplifier wiring kit:
- Everything Included – the best amp kits that are available to buy will have everything included in the bundle. Make sure that you double check this before making your online purchase. The best type of amp wiring kits will include: good quality RCA cables which are at least 16ft in length, positive wire at least 18ft in length, ground wire, speaker wire, remote wire, crimp ring terminals (which give you a stronger, more solid connection), good quality fuse holder & fuse, zip ties (to keep everything neat and tidy).
- Wire Length – this is very important. You should try to find an amp kit that includes a wire of around 18ft. You will need a wire with enough length to stretch the battery positive terminal to the amplifier in your vehicle. The RCA and remote cables should measure around 15-16ft also. Avoid wires around 12ft as these are likely to be too short and cause tension.
- Don’t Get Scammed! The first thing you will need to establish when buying your amp wiring kit, is which gauge size to buy. If you’re unsure then it’s best to opt for an 8 gauge wire as this is the standard for most amps. In fact most amps use a maximum of 8 or 4 gauge wire. The thing to note at this point is that many companies lie about the gauge size and tell you that the wire is gauge 4 when in fact it’s much smaller and the insulation is thicker to give the illusion of a thicker wire. Make sure you read the reviews before you buy so you know what you’re getting is genuine. Do your research and never opt for the cheapest option.
- Fuse Holder – make sure you buy an amp wiring kit with the best quality fuse holder. A high quality fuse holder is one of the most important components of an amp wiring kit. Don’t buy the cheapest! The best type to go for are ANL and AGU fuse holders. The benefits of these? They’re easier to instal, show the fuse element if it’s blown and are normally resistant to heat and moisture too.
- Good Value – don’t be lured into false economy and buy the cheapest! I know we keep saying this but make sure you find the best quality for your dollars without compromising on quality.
Copper vs. Copper Coated Aluminum Wire
When you start to research different amp wiring kits, you will encounter wires which are made from copper and many which are copper coated. Which is the best?
Let’s first look at the differences:
- Copper Wire
Much more expensive than copper coated wire, this pure type of wire can cost up to four times more than aluminium wire. The reason for this? It’s a good conductor of electricity. Not only this, but copper wire has been used for many years and it’s largely considered to be the better option for wiring.
- Copper Coated Aluminium Wire
This type of wire is normally made from strands of aluminium wire which has been coated with a very thin layer of copper. Copper coated aluminium wire (or CCA wire) usually looks the same as pure copper wire but will act differently. You see, the main difference between these wires is that copper coated aluminium wire is a cheaper alternative. As with all wires (both copper and copper coated) the strand sizes and quality will differ from brand to brand but generally the insulating material is the same and made from PVC or a silicone based material. Copper coated aluminium wire provides a difference when it comes to resistance. Aluminium isn’t the best conductor of electricity in comparison to silver, but when aluminium is coated with copper you will actually find that it can deliver the same conductivity with a higher resistance. One of the downsides to the type of wire is the quality and flexibility. A copper coated aluminium wire won’t withstand the same amount of flexing as a pure copper wire. Another thing to look for is honest advertising as some products are sold as pure copper and when you cut the wire you discover that they’re actually copper coated aluminum wires.
How to Install to Amp Wiring Kit
If you’ve decided to take on the job of installing your amp wiring kit yourself then you might want to do your research first and get a buddy to help you along the way. But here are the basics to installing an amp writing kit:
- Mount Your Amp On A Safe Surface – make sure that it’s a solid surface that can’t conduct electricity, in a safe spot that cannot fly off in an accident and hurt someone and at least 3ft from the stereo itself. You’ll then need to disconnect the negative battery terminal to prevent getting an electric shock.
- Pass Wire Through Firewall – use an empty rubber grommet in a factory hole for this or drill a hole carefully, using a rust protector afterwards.
- Attach The Power Wire To The Battery – the long (usually around 16-20ft) power wire will need to run through your car’s interior. Making sure that the wire won’t get caught or pulled, run the wire through the car’s body. Under the carpet is ideal but you will need to remove the rocker panel and kick panel covers first.
- Instal The Fuse Holder – next you will need to find a good spot next to your battery and instal and secure with a cable tie for added safety.
- Connect The Power Wire To The Amp – attach the wire to the positive terminal and never the battery post and secure the wire with plastic wire ties.
- Attach RCA Cables – you’ll now need to find your RCA cables and remote turn-on lead (blue cable with white line) and run them through your vehicle the same way you did with the power wire but on the opposite side.
- Connect Speaker Wires – you must place these wires away from the power wires when connecting. This prevents sound interference.
- Connect The Amp’s Negative Terminal – using the shorter negative power wire, connect the negative terminal to the car’s chassis ground.
- Check All Wires – you must do this first before you insert the main power wire fuse. Ensure everything is in the right place first! You’ll then be ready to connect the negative battery terminal. Remember: all your wires should be tight and secure, don’t forget to check the ground wire too.
- Check The Amp – you’re now ready to turn on the amp and set the input gain levels to their lowest setting. Also turn off bass boost or any other filters at this stage. Reconnect your car’s negative battery cable and turn on the radio. Check to see that the sound is coming from each speaker and that this is equal. Then turn up the volume until you actually hear distortion so you can then set it just a fraction below that level. Ideally you wouldn’t hear any distortion. This is an indicator of a good head unit. Repeat this process for the input gain and other components and then you should be good to go!

Choosing an amp wiring kit depends on a number of factors, generally speaking. Look for a trusted brand with good quality wires that meet the exact specifications ie if it says 8 gauge it needs to be 8 gauge. You will need sufficient wire length and a good fuse holder and power wire connectors too. Do your research first, find a good brand offering good value for money.
