five steps to help you install car amplifier correctly

Car amplifier is an electronic device in a radio or aftermarket car stereo  which causes sounds or signals to get louder. In this instruction we will give you a vivid account and explanation about how to set up a car amplifier on your own with tools listed below. It is of great importance for you to work your way down in a proper way and be clear about which features are indispensable for you in a car amplifier.

Besides, you have to take the budget for the system in the future and the level of quality you desire to achieve into consideration. Here is a list of materials and tools you need for the Car Amplifier installation process:

Amplifier
Wiring kit and wires
Pliers
Screwdrivers and screws
Installation manual
Electrical drill and drill bits
Contact tips

Step 1
Select a suitable amplifier type.. If you just intend to power either the front or only the rear speakers, a two-channel amp with a matching power rating will be enough. If you aim to run all four channels, a four-channel amplifier will satisfy your need. The best option will be a multi-channel amplifier.

Generally speaking, it is a six-channel amplifier, with which you are able to bridge the two channels into one to power the subwoofer. As to the rest of the power, they will go to the speakers. In this case, the more power there is, the better will it be. The power is not only for the purpose of loudness, but also for the higher sound quality.

Besides, you have to think over the quantity of power sources inside the housing. Two are better—one for the subwoofers and another for wide band channels.

Step 2
Install the car amplifier rack. Pay full attention when it comes to selecting a new place for the installation of amplifier rack. In order to keep the amplifier from overheating, make sure that the amplifier gets enough air circulation.

As we all know, lots of heat can be produced while raising the volumes, which can lead to damage to the electronic parts. Thus it is of great necessity and importance for you to make certain of the airflow so as to make the components achieve good performance and reliability. Install the amplifier to a wooden rack can help minimize unnecessary noise.

Step 3
Build the new amplifier. Make sure that there is no cover on the amplifier; or else a fan will be needed to cool it. Besides, the amplifier should be appropriately powered. Generally, it is located in the car trunk. Set up the safety fuse as near as possible to terminal “+” of the storage battery and connect it to the battery.

An amplifier features its own fuses so to protect against melting of the cable’s insulation, short-circuiting, or fire. The size of the fuse should be the same or less rating as the fuses used by the amplifier. Use silicone lubricant to protect against corrosion.

Step 4
Connect the wire with a fork contact tip from the storage battery to the +12V contact connector on the amplifier. Fortify the places with plastic insulated tubing where fire could pass through or where the wire could easily bend.

Besides, you have to avoid placing switches or devices with large current flow in these places. In the engine, fasten wire on the previously laid wires with cable tightening clamps. Connect to a clean metallic surface where there’s no paint for good contact with the car’s metal,

Step 5
Use a wire brush to clean the metal, then drill the opening, and screw the contact washer to the car body. Protect this connection using silicone lubricant. Cover the connection with paint after connection of the wire also works to protect.

With power to the amplifier, wire up the speakers, radio to finish hooking up the system. Refer to the accompanying manual to adjust the settings for your new amplifier. You are now on the way to show off your new sound system.
