How to install car amplifier and subwoofer

I. What is an amplifier and a subwoofer?

If you happen to attend a car show, you will encounter modified cars blasting loud music. These cars don’t just pull up in car shows with their car’s factory speakers. They spend a lot of money, depending on the setup, so their car’s audio system could stand out against the other.

This is where amplifiers and subwoofers are usually needed. As the name implies, an amplifier helps increase and amplify the power sent by the installed head unit or infotainment system. The sound quality tends to decrease as the volume is increased. So by adding an amplifier, the sound quality gets richer despite played at high volume.

A good setup also improves aesthetics

On the other hand, a subwoofer is a speaker designed primarily to produce low-end frequencies or bass. Most cars don’t come with subwoofers as standard since they can affect the final pricing. Most standard speakers produce bass, but not as rich as a dedicated subwoofer.

If subwoofers specialize in low-end frequencies, then tweeters specialize in high-end frequencies

You can get an amplifier in the aftermarket for Php 800 to Php 4,000, depending on the quality. Usually, the more channels installed, the more expensive the amplifier gets. Meanwhile, you can get a subwoofer for Php 3,000 to Php 12,000 in the aftermarket. Installing one subwoofer is enough for a high-quality boomy listening experience. You can install more than one if you feel a need for more bass.

Be sure to use the right tools to avoid unwanted damage

If you have your amplifier and subwoofer with you now or planning to get them soon, here are the steps on how to install car amplifier and subwoofer in your car.

II. How to install car amplifier and subwoofer: 8 steps to follow

Fortunately, the installation process of amplifier and subwoofer is pretty much the same in most cars. As long as you still have your car’s factory head unit, then you are good to go. If you own a car that is listed for Php 5 million or more, we recommend you contact your car dealer as panels and wirings could be damaged.

Step 1: The first step is to disconnect the positive terminal of your car battery. Working with live power could turn out badly.

Step 2: Find a perfect spot to place your amplifier. It should be away from your subwoofer by at least three feet to avoid static noise or distortion. On the other hand, subwoofers are huge speakers so they are highly recommended to be placed in the trunk or cargo space.

Step 3: You need two wires for your amplifiers, namely the power wire and ground wire. The power wire should be connected directly to the car battery. Meanwhile, the ground wire can be connected to any bare metal of your car. If the chosen grounding point has rust or paint, remove it first to avoid static noise or distortion.

Step 4: Install an inline fuse in your power wire. The inline fuse should be positioned near the battery for optimum operation. The recommended distance is five inches. To do this, just cut your power line then install both ends on your inline fuse.

Step 5: We recommend you add a wire cover to your power wire to avoid damage from engine heat.

Step 6: Remove the panel on your head unit to gain access to its wiring. Find the speaker wires and tap those using posi-taps for easier connection. The tapped wires will then be connected to the amplifier using a converter to an RCA connection.

Step 7: Connect the subwoofer to the amplifier. Before placing the panels back in place, adjust the gain setting in the amplifier in your desired configuration. If you are unsure of the proper settings, you can call your friend or someone who knows about mixing sound so you can have an optimum listening experience. Be sure that there must be no static noise or distortion.

Step 8: If the sound is already good and rich, you can now place back the removed panels inside your car. Connect the positive ring from the power wire of your amplifier to the positive battery lead of your car and secure it with the disconnected positive terminal.
