8 Steps To Install Car Amplifiers

Getting The Best Car Amplifier

You might be wondering where to get the best amplifier to install in your car, but you don’t need to because you are in the right place to get the help that you require. Amplifiers come in someconfigurations, and it will all depend on how many speakers that are available in your sound system.

Each speaker will require one amplifier. If you have an existing system, and you are adding a subwoofer, then all you need is just one channel of the amplifier. If your car has a good double din radio, a 2-channel can be used to power two coaxial speakers and two woofers, or bridge it to run a single sub.

Things You Require To Install The Amplifier

To correctly install a car amplifier is not easy, but as long as you have the right tools, you will be able to successfully finish it on your own without having to involve a technician. As long as you do it correctly, you will come up with a great system which produces quality sound at no extra cost. You will require the following:

  • Main power wire
  • Have a nonmetal surface where to mount the amplifier
  • Have a firewall where to pass the electricity – rubber is ideal
  • Incline fuse for interconnection
  • Ground wire
  • RCA cables
  • Remote turn-on wire
  • Speaker wires
  • Connector plugs which will be suitable for the head unit
  • File or sandpaper to remove dirt, paint or stains from the surface
  • Speakers
  • Amp

Time To Do The Installation – Things to Consider

The Size of The Car

Once you are ready with the requirements, you will need to embark on the installation process. The size of the amp to buy will be dependent on the space you are going to fix it in. I did fix mine in the car trunk, but you can do it in the boot of your car. Depending on the car you are driving, you might have ample space or limited; I drive an SUV and thus had limited space. So if you are in the same category like me, you can decide to fix your amp between, behind, or under the seats.

How The Wiring Will be Done

You have to consider how you are going to do the wiring for the amp with the power wire and head unit of the stereo, to the battery. I ran the wiring on the trimmed floor that ran along the bottom door sills. If there are any preexisting wiring, follow that. For the RCA cables, make sure that you route them on the opposite side of the car to the power wires to prevent an accident occurring. When doing all this, you should remember that, the opposite side of your battery and make the most direct path to it with the main power wire.

Heat From The Amp

Before you start the installation, remember that the amp generates heat and thus, there should be cooling fans which should be placed in a place where maximum airflow is allowed. If you are fixing a subwoofer(as was my case), make sure you mount the amplifier on the side of the box. They should be high up to maximize airflow and to avoid damage.

Main Power Wire

The main power wire to the battery should pass through a firewall through the holes which are already there in your car. If it’s not possible, then drill new hole through the firewall

Step By Step Installation of Car Amplifier

  1. Take the wires and make sure that the insulation is removed from their ends, leaving enough space to attach a connector plug. Depending on what system you are using, you might be required to use bare wires without connector plug. If that is so, then you will have to bare the wire back using the right length that will suit the depth of the sockets for connection. 
  1. You will then need to connect the ground wire to a metal point which is connected to the chassis of the car or check out the dedicated grounding point of your car. The connection should be to the bare metal. If there is any painting, rust or dirt to the surface, scrub it off using sandpaper or a file to enable good grounding connection.
  1. Connect the speaker leads, RCA leads, and remote turn on from the amp into the back of the head unit. In case your head unit does not have a remote turn on wire, you will have to wire the amp to another power wire running from your accessories on the ignition switch or power wire to your head unit. This will help in preventing your car battery getting drained when you turn your ignition off, and the amp stays switched on as it will make sure that it is switched off.
  1. It is now time to connect the subwoofer, front, and rear speaker wires from the amp to the corresponding speakers
  2. Run the power lead from the amp through the hole in the firewall to the battery. When doing so, make sure that it is on the opposite side of the car to the RCA cables.
  1. At this point, you will need to install the inline infuse to the main power wire; make sure that all the deadends and connections are crimped. Have a solid structure to mount the fuse holder in the engine bay depending on its size. The electrical system of your car has to be protected by installing an inline fuse to closer to the battery.
  1. The main wire and the amp have to be connected to the positive battery lead, reconnecting the positive battery terminal to the positive battery lead. Then, secure all the wiring using cable ties.
  1. Using fade, balance, and subwoofer setting test all the operations on the head unit to ensure that, each speaker individually can work without distortion or static.
