Our review will not only cover the best amp wiring kits available on the market, but it will also discuss important considerations to take when purchasing an amp wiring kit.

Buying Guide for Amp Wiring Kits

Before looking at the top amp wiring kits, you’ll need to determine which type of wiring kit you need. There are two different types of amp wiring kits to choose from: a complete wiring kit and a power kit.

Complete Amp Wiring Kit

This kit will come with virtually everything you will need to connect an amplifier to your vehicle properly. This includes:

  • Speaker wire
  • Power & ground wire
  • RCA cables
  • Fuse holders
  • Grommets
  • Terminals

Power Kit

The biggest difference between a complete amp wiring kit and a power kit is that the power kit will not include speaker wire or RCA cables. The benefit to a power kit is that many include extra bits of hardware, which may include:

  • Grommets
  • Connectors
  • Wing terminals
  • Cable ties

When it comes to choosing between a complete amp wiring kit and a power kit, the best option is usually to go for the complete kit. While having a power kit can certainly prove useful, having a full array of options will enable you to complete each step of the wiring process successfully.

Additionally, the extra hardware that comes with a power kit can easily be purchased at a local hardware store, and at a much lower price.

Wire Sizing

It is imperative that the amp wiring kit that you purchase has the correct wire size to match the amplifier. Each amp wiring kit comes with different wire dimensions, meaning that there is no “one size fits all” solution for amplifiers and wiring kits.

Whether the amp is purchased first or the wiring kit is purchased first, both the cable and wire sizes need to match to  real life example of amplifier wiring basics and instructionseffectively install the amp into your vehicle.  

This is important because the cables and wires in the amp wiring kit determine the amount of power that is sent to the amp. If the amplifier receives more power than what it is designed for, this could cause sound issues and even damage the amp itself.

If all these seems too complex, please check out:

The most common wire sizes for car amplifiers are 1/0-gauge, 4-gauge, and 8-gauge. For quick reference, here is a list of wire gauges and the wattage that each is best suited for:

Amp Wiring Sizes

  • 1/0 AWG— 1,000+ watts
  • 4 AWG— 400-1,000 watts
  • 8 AWG— 200-400 watts
  • 10 AWG— 100-200 watts

Before purchasing an amp wiring kit, make sure that you look at the manufacturer specifications for your amplifier to ensure that you are getting the proper wire size to accommodate the wattage of the amp. Not only will this result in the best performance, but it will also preserve the quality of the amp.

Sound System Complexity

As sound systems increase in complexity, they will also increase in amplifier needs. This often means installing more than one amp at a time. One of the most efficient ways to do this is through purchasing a dual amp wiring kit, which comes with distribution blocks and dual fuses for two amplifiers.

Having a distribution block is crucial since it allows for more than one amplifier to run from one power wire. Additional outputs will allow both amplifiers to be connected to the same wire.

If you’re planning on installing more than one amp, you’ll have to be aware of the sizes of the fuses and their holders. Without proper matching, they will create a power surge and potentially damage the sound system.

In these cases, the fuse rating of the amp wiring kit should also match the amplifier. If the fuse rating is slightly higher, that generally works well enough without damaging the system, but a perfect match will always be best.

For more than one amp, simply add the total amperages of all amplifiers and use that number to match the fuse rating.
