How to Install Car Amplifier and Subwoofer? Enjoy Every moment while Driving

A mind-blowing sound can enrich your journey full of joy and excitement. But, is your car speaker provides high-quality sound so does your home speaker. So, it’s high time you should gear up your car speaker by installing a car amplifier and subwoofer. 

Though manufacturers create speakers for audiophiles, they don't set up the speakers in your car. It's upon to you how you set up the speaker. In fact, sound quality mostly depends on the installation. Out of ten, nine speakers drastically decrease the sound quality because of faulty wiring.

Here, you'll know the easiest way to install a car amplifier and subwoofer to get the best sound quality to content your mind as an audiophile.

Steps of installing car amplifier and subwoofer

A subwoofer can make your journey enjoyable for a long time. Hence, you need an amplifier and a subwoofer which must be matched with each other. However, the amplifier must be more powerful than the subwoofer so that the subwoofer can't slip. Because clipping is responsible for creating bass distortion. However, follow the below steps:

Buy/ gather high-quality equipment

The most important thing for installation is the wiring kits which you can find any electrical store. Buy at least 4 gauge wire and an in-line fuse. Remember, the wire must be covered with the high-quality insulator. 

However, most of the users use an aftermarket head unit. If your one is also an aftermarket head unit, collect a precise wiring harness from any electronics store. Once you get it, unscrew the stereo unit and then plug it to the wiring harness. Also, don’t forget to plug in the other end to the stereo. Also, always take the wiring harness similar size to the stereo.

Run amp wires

Now, figure out the place where you want to keep your amplifier. Then, put the beginning end of the power wire and keep an extra foot wire outside the amplifier. Here, the power cable may be red. Now hide the power wire under the hood. Your car may be one of the vehicles which come with a plastic/ rubber insert to keep the wire hidden.

After hiding the power cable, run it through the firewall. Here, if you need to drill a hole in the firewall, do it consciously so that it can’t hit the other side or the power line. Also, it would help if you were careful about moving objects to its safety. After all, you can use electrical tape at each end of the wire for secured and added protection.

Relocate power cable perfectly

Now it’s time to connect the power. A first, disconnect the power wire from the battery and then connect it to the amplifier’s wire. The connection will get power from the vehicle’s battery. Don’t attach it now. After connecting the power wire to the amplifier’s wire, connect the inline fuse to the power wire. To attach the inline fuse, you have to cut the power wire so that you can insert the inline fuse. Remember that, the amperage of the fuse must be matched with the gauge size.

Place the Amplifier

An appropriate placement can enhance you enjoy many times. Also, it provides energetic inspiration while you are driving the car. So, place your amplifier the right space where you want it. After that, connect the amp with the wire. Now, ground the amp with a bolt (bare metal) and then unscrew it from the seat attached. Then screw it so that the amplifier can't move while the vehicle moves.

Set RCA Jacks

Every aftermarket stereo comes with 2 RCA jacks on the back. Now, run the RCA jacks by entering the input jack to the “IN” port of the amplifier. It will provide natural but deep bass with crystal clear sound. Never try to run RCA jacks to the power lines. It can destroy your stereo as well as can produce much distortion.

Use Remote Blue Wire

Your aftermarket stereo comes with a blue wire in the back from the wiring harness. As the cables come attached, you have to splice, snip them. Then attached the old end with tape and run the remote wire to your amp.

If you use a stock head unit, you need a toggle switch by which you can control your amp effectively. Then mount the head unit to a cool place or hide it under the seat. Now cut the toggle and attach it to one terminal. The other end should be attached to another one. Now run the remote wire back to the amplifier.

Prevent excessive voltage

Always use a capacitor as close as possible to the amp. It helps to prevent excessive voltage caused by deep base hits. Now, cut the power wire and attach it to the battery cable. Before connecting, you must have to charge it with a resistor, at least 1K ohm which never gets hot. Also, it requires a few seconds to load.

Here is a caution. Never touch any electrical with barehanded. By the way, ground the cap with a voltmeter placing in it. Now, put a resistor inside the lid. After that, attach the power wire with a resistor at the other end and cover it with the tape. Now, the cap will be charged soon for its 12.0 volts.

Run the Power Wire

If you have both stereo and remote wire, connect the remote cable to the power wire before inserting the amp. The remote wire will automatically turn on the amp power. However, if you don't have a stereo head unit, you may need to turn on the amp manually.  Never forget to turn off the amp before leaving your car.

Connect Subwoofer to the Amplifier

Now, connect the wires of the subwoofer to the amplifier and screw them in. After connecting the subwoofer, play the music and increase the volume gradually. The mid-level sound is precise to listen. Tune the whole set until your mind-contented sound comes.

Final Remarks

Nowadays most amps come with complete wiring kit. But when you want to play subwoofer and amplifier, it requires some technical knowledge. But, it’s not too difficult to complete for a DIY enthusiast. Also, it saves a lot of bucks from spending to buy a new audio set. However, always follow the instructions provided by the manufacturers. It helps you get the best performance and longevity.
