Installing your new amp can be a tricky task. Amplifier wiring kits can come in all different types of configurations. There are so many different abbreviations like RCA, OFC and CCA, it can get confusing. Not to mention the many variations of wiring gauge sizes; however, following these five fast facts about amplifiers wiring kits, will help you purchase and install the correct kit for your car.

  1. Understand the Limitations of Your Budget

Just like buying any other product it is extremely important to understand your budget and what limitations might come with it. Do not try to cut corners and save money in a place like wiring because certain wiring types will not be able to handle higher powered systems.

  1. Know the Difference Between OFC vs. CCA

One of the first things you must know is the type of wire you will be using. You have to understand the difference between OFC vs. CCA. The more affordable option out of the two is Copper-Clad Aluminum wire or CCA. CCA wire is best used on lower powered systems on a budget.  Oxygen Free Copper wiring or OFC is the much superior option because of the power transfer abilities. It also increases conductivity and it puts less strain on your vehicle’s electrical system. For more information read our article about wiring options: OFC VS. CCA WIRE: THE RUNDOWN.

  1. Buy a Complete Kit to Avoid the Headache

If you don’t want to go through all of the trouble of buying all of the individual wires and cables, it is best to buy a complete kit.  Complete Kits will include speaker wire, power and ground wire, RCA cables, remote turn-on wire, fuse holders, grommets and terminals. They will include almost everything you need.

  1. Make Sure to Use the Right Size Wire

Before buying an amplifier wiring kit it is important to know what size wire you actually need. Not all wiring kits fit every amplifier; they are not universal. The kit needs to be matched up to the amp. Use the proper wire gauge to make sure that your amp receives the correct amount of power. Refer to this chart from our article: AMPLIFIER WIRING KIT BUYING GUIDE.

10 AWG 100-200 Watts


  1. Make Sure to Always Conceal Wires When Finished

Concealing the wires not only gives your vehicle a cleaner finished look, but it also is very important for safety reasons as well. Wires should not interfere with safe vehicle operation. It is usually best to hide the wires under a door scuff plate or under the dash. In more difficult places with moving parts, such as behind the dash, it is best to secure wire with plastic wire ties.
