If you enjoy listening to music while driving, your car probably already has a powerful sound system that provides distortion-free sound even at high volumes. However, you must pay attention to every detail of the sounds if you want to truly enjoy great music. Bass is one of the most crucial components of sound. If you want tight, clean bass, an 8 inch subwoofer is a good option.
In this article, we will be reviewing things to consider before purchasing an 8-inch subwoofer for deep bass, the best 8-inch subwoofer for deep bass, and all you need to know about them.
Choosing The Best 8 Inch Subwoofer for Deep Bass
Before you install an 8-inch bass-heavy sound system in your car, here are some things to consider before purchasing a subwoofer:
1. Power Rating
The power output rating of a subwoofer is one aspect that directly impacts its performance. The subwoofer’s maximum power output is indicated by its peak power rating. Therefore, you will be able to use the subwoofer at louder volumes if it has a higher peak power rating.
Since the peak power rating is only temporary, you should also look at the RMS power rating. The RMS power rating is the maximum continuous power that a subwoofer can handle.
But make sure the RMS rating matches the amplifier. Your amp should be able to pump out 75 to 150 percent of the subwoofer power rating.
2. Sensitivity
Another important factor to take into consideration is sensitivity. The subwoofer’s sensitivity tells you how well it will convert power into output volume and is measured in decibels (dB).
Less power is required for sound production by a speaker with a higher decibel rating. Because of this, a speaker that has a 200 watt RMS output can sound louder than one that has a 250 watt rating as long as the former has a higher decibel rating.
3. Frequency Range
The frequency range of a subwoofer speaks to both the upper and lower limits of its detectable frequency range. The lower limit of the best subwoofers is often in the 20 to 30 Hz region.
4. Impedance
Whether it’s a robust gaming headset, an audiophile open-back headphone, or a subwoofer, practically all audio output devices have an impedance rating.
Impedance refers to the electrical resistance found inside the speaker circuitry. You should give this component considerably more consideration if you intend to use an amplifier. Your subwoofer and amplifier should be matched when it comes to impedance.
Best 8-Inch Subwoofer For Deep Bass
There are many different models available out there that vary in terms of power output capacity, number of coils, impedance, frequency response, etc. It can get quite difficult to find the right subwoofer, especially if you are looking for a compact option.
To help you with that, the best options that are powered by an 8-inch driver are shortlisted below;
1. Best Overall: Rockford Fosgate P3SD2-8 Subwoofer
It has dual voice coils with a resistance of 2 ohms, a power range of 150 watts RMS, and a maximum power handling of 300 watts. The eight-inch woofer has a durable, long-lasting anodized aluminum dust cover and cone.

The dual 2-ohm voice coils provide flexibility and adaptability in terms of wiring and allow you to connect it to a low-impedance amplifier. Also, there’s the spider venting basket. It dissipates heat efficiently, meaning you’ll get hours of maxed-out-volume performance without overheating.
The bass it produces is rich and deep, and it is distortion-free. Without ever showing symptoms of fatigue, the tinsel leads can withstand a lot of violent cone motions.
Pros
- Overheating is reduced via integrated spider venting.
- It appears and feels strong and resilient.
- Dual 2-ohm voice coils allow for flexible wiring.
Cons
- Low peak power output
- Not budget friendly
2. Pyle PLPW8D Car Subwoofer
It is both powerful and power-efficient thanks to a built-in 40 oz magnet that provides up to 89 dB sensitivity.

You may also wire the subwoofer as either 4 or 8 Ohms depending on the power of your amplifier thanks to the dual 4 Ohm impedance.
Pros
- The compatibility with amplifiers is decent.
- Power output capability of up to 800 Watts
- Powered by a built-in 40 oz magnet
- Dual 4 and 8 IMpedance wiring modes
Cons
- Power capacity could have been better
3. Skar Audio IX-8 D4 Subwoofer
A 30 ounce magnet that can give increased power output without any power loss powers – the Skar Audio IX-8 D4 subwoofer.

This subwoofer is the perfect choice for small to medium-sized cars because it has an RMS power rating of roughly 150 Watts and a peak power rating that can reach 300 Watts. This subwoofer’s frequency response range extends from 30 Hz to 350 Hz, guaranteeing a strong bass response under all circumstances.
Pros
- Range of frequency response: 30 Hz to 350 Hz
- Available sensitivity rating of 6 dB
- Up to 800 Watts power output capacity
Cons
- Low peak power output capacity
4. CT Sounds TROPO-8-D2
Another economical option from our list of the finest 8-inch subwoofers is the CT Sounds TROPO-8-D2, which offers excellent characteristics at a reasonable price.

The subwoofer has a power output capacity of up to 800 Watts, which many other high-end choices on the market seem to lack. Additionally, you will receive an RMS power rating of 400 Watts, which is nearly twice as much as what the majority of other options would provide.
The subwoofer’s foam covering is very flexible to prevent any kind of external damage. The subwoofer also has a cutting-edge air cooling system, which is supported rigidly by a distinctive chrome-plated bottom plate.
Pros
- Features a cutting-edge air cooling system
- High RMS and peak power output capacity
- Very strong and durable
Cons
- The overall size is a little larger than the other options
Conclusion
Selecting an 8-inch subwoofer for bass just got easier! Remember to carefully tick the boxes for the considerations as listed earlier. With that, you can be confident of settling for the best.
