Deep bass audio experience that’s what all the car audio enthusiasts want but reality is much harsh. You may have the best subwoofer and the best amp, yet they never assure you the deep bass you want. So many factors have to be taken in consideration for achieving the deep bass. So here we are going to guide you to the straight path of deep bass and this guidance will help you to understand many things related to a clear deep bass.
Usually it may take a little effort from your side, but once you understand the reasons behind lack of deep bass from your subwoofer, “how to get deep bass from car subwoofer” this question will be abandoned from your mind forever. So let’s dive into the details.

Reasons Behind Lacking Deep Bass in Car
Even if you have the best amp settings for a high end subwoofer, it may have hoarse bass or distorted bass. So here we’ll explain the car subwoofer’s underperformance and it may also assist you in choosing the right subwoofer for your car.
RMS of the Amp and Subwoofer
Most of you look for the watt on the amp and match it with your subwoofer. A 1200 watt amplifier means the maximum watt it can use, but a subwoofer doesn’t require 1200 watt all the time, so here you must match the RMS value for both the amplifier and the subwoofer. Also the impedance is another crucial factor, meaning if your subwoofer is 2 ohm, you must need a 2 ohm amplifier for running that subwoofer. Now it is relatable, if the RMS and impedance don’t match, then the subwoofer may not produce expected bass quality.
Low Battery Voltage
Surely the amplifier will draw the power from the car’s battery, if the battery isn’t capable enough to produce that much voltage to produce the right amount of RMS then the quality of the subwoofer bass will drop.
Small Gauge Wire
The factory wiring doesn’t create issues for most of you, because we just have a good amplifier and subwoofer. But if you make it filled with high end speakers, head unit, amplifier and few subwoofers, then definitely you should change the positive wire that goes from the battery to the alternator to zero gauge and negative wire that goes to the engine and ground wire to zero gauge.
Too small Enclosure
Enclosure is the box where you are going to put the subwoofer. For achieving deep bass from a subwoofer diy enclosure, you must use either a sealed or ported enclosure box. Every subwoofer has a recommended enclosure size. Try to maintain that size.
So far, these are primary reasons that may distort subwoofer sound, yet after providing all the best setup for your subwoofer, if you don’t get the deep bass you desire, there you need some adjustments of speakers, subs and their tuning
Ensuring the Most Boom from your subwoofer
Here we’ll show you the best amp settings for having the low deep bass from the subwoofer and how to get deep bass from car subwoofers. So ensuring a clear deep bass from your car subwoofer, there’s no way you can escape any steps we’re going to describe here.
First, you must need a high end amplifier. The higher the amplifier’s quality the more adjustments and control you’ll get to fine tuning the subwoofer sound. So you must ensure the amplifier has subsonic, low-pass and bass boost filters available. Also, change your factory head unit if it is too old and get an aftermarket unit. The aftermarket unit doesn’t only produce clear sound signals to the amplifier. Also they offer built-in equalizers app, so tuning the subwoofer with the app will be easier in the future.
Step-1: Checking the Wiring
This time you must check the wiring of your ground wires. Connect them directly with the car’s frame. Because the heavy metal of the frame helps any electrical surges go to the ground directly. If the grounding is not up to the mark, it may cause distorted bass too.
Step-2: Clearing the Distortion
Tuning a car subwoofer demands the removal of the distortion at very first. Because just before the distortion starts, you get the best sound output from your speakers and subs. So set the amp gain low and play music and turn up the volume until distortion starts to come. This is the highest volume you can get from your speakers and subs.
Now turn the gain up and your volume knob is on the highest distortion level. Keep turning the gain knob until you hear the distortion again. Keep the gain at its highest where it doesn’t produce any distortion at highest distortion less volume.
So this is the basic line for your car audio sound. From here on, the adjustment of the subwoofer will come.
Step: 3: Adjust the Low-pass Filter
Listen carefully here, almost all the quality amps have car subwoofer gain settings. That means they will have one gain dedicated for speakers and another gain dedicated for subwoofers. So set the subwoofer gain flat, Now set low-pass filter around 60hz, it means all the low frequencies than 60 Hz, will pass through amp and go to the subwoofer. You know all the bass sounds and beats are much lower than 60hz. Also, normal music is much higher than 60 Hz.
So far if you do all these 3 tuning. You should be able to listen to the low deep bass you desire. A little adjustment in bass boost will help you achieve how to get deep bass from your car subwoofer. Yet if it doesn’t satisfy you, use the bass boost, a little adjustment in bass boost will bring a lot of boom. Too much bass boat adjustment can bring up distortion again. So be careful about using bass boost, you can damage the subwoofer permanently by misusing it.
FAQ
1. Is it possible to stop vibration from the subwoofer in a car?
– Subwoofers may cause vibration in your car because of loud bass or because of lack of enclosure around the subwoofer. So use enclosure and even if it creates vibration, then try to use vibration dampening material.inside the car.
2. How to make my subwoofer boom deeper?
– First, you need a quality subwoofer, amp and wiring. Then match the RMS wattage of both the subwoofer and the amp. Try to have an aftermarket headunit your car’s head unit is too old. Finally, tune the subwoofer through the amplifier.
Final Words
It may look a bit difficult at first, but remember you may change speakers, amplifiers, subwoofers many times in your life and if you go to a car audio engineer every time it doesn’t look cost effective at all. So try it on your own, because any mistake wouldn’t blow your sound system away if you follow our process. Also, we suggest you not tune the sound system both by the amp and the factory head unit. You better do it directly from the amp.
