So you want a great bass system for your car? Before deciding what you want to buy, don’t you think this guide will help you?

You can compare features and other specifications of subs and then make the final choice. Sounds good to us, what about you?

  • Power Ratings

Given a subwoofer’s power handling performance, managing bass settings can be possible. If you want a very powerful subwoofer, you need to focus more on its RMS than peak power ratings.

And why do you think that is? Because RMS ratings handle and measure the continuity of sound output. Taking RMS power ratings into consideration is useful than measuring peak power ratings.

  • Sensitivity

To get to high output, measuring sensitivity is as important as power ratings. With either one, the other ceases to exist. That said, if you buy a subwoofer with high sensitivity needs less juice to produce higher output. And a subwoofer with low sensitivity needs more juice to produce the same amount of sound.

  • Frequency Range

The next big skill of subwoofers is frequency range. This helps you determine how low a sound your subwoofer can produce. But the frequency range of a subwoofer depends on many other factors. One of them includes the design and durability of a subwoofer. (Top 10 loudest subwoofers and speakers in the world)

If you know a thing or two about subwoofers, you’d know that by buying one, you don’t get that perfect bass. Given its performance potential, placement and connectivity are essential. That’s what we’re going to discuss a bit about below.


It’s worth making an effort to get your subwoofer’s bass correct. It’s not enough to install your subwoofer wherever seems convenient. A little more tweaking makes the experience more productive.

Buying 8-inch subwoofers means you’re buying practical ones. You would have to make your speakers and sub work together to get the perfect sound.

Based on research, we found that larger subwoofers don’t demand as much tuning as small ones. This means you’re running with the big guns here!

The trick is to ensure the bass doesn’t sound gloomy and distorted. So for testing purposes, you can place your subwoofer as close to your speakers as possible. As you will see, the improved location will do wonders to improve sound quality and depth.


The last and most important step is fine-tuning your subwoofer for paramount performance. Once you buy a sub, maintaining hard-hitting sounds and sound linearity is important. You want something with a durable polypropylene design. Plus, you want something that offers heat dissipation, but without the breakdown of components.

Using connectors for hooking up the sub to the rest of the sound equipment can seem intimidating. Especially for novices.

But let us tell you that using connectors is one of the simplest and fastest ways to install subs.

  • The first thing to do is fine-tune your speaker level. Any cracking or flapping sound can ruin your sub’s sound quality. For that, you have to set your amp small and increase the receiver’s volume. This is to test the sound limit until it stops playing distortion-free music.
    Once you’ve found your volume limit, do the same with your amp gain. Once you’ve got both down to comfortable levels, it’s time to flatten the signal.

That’s when you either have to alter the subwoofer level down to zero or receiver’s bass control down to “flat.” And if you have a crossover, which is considered a low-pass filter in most systems, turn it off.

  • When that’s said and done, start playing music. But only through the receiver. Keep increasing amp gain until the subwoofer is much louder than speakers. All this without distortion.
  • Next, continue listening to the sounds while adjusting the subwoofer’s low-pass filter settings. Reduce the frequency until all high-frequency sounds fade away. This is to fine-tune your sub’s low-pass filter to do what it’s supposed to. And that is to maintain optimal tone control.
  • The final step is to blend your speakers’ and sub’s frequencies together for the last draw. Begin by increasing the receiver’s volume to its highest, distortion-free limit. Then switch back to the sub’s amp gain and increase that too. That should do most of the trick. Congratulations, you’re an audiophile!



This guide will be the most helpful for most you. That is if you’re looking to add a powerful bass system to your already established sound system. Buying subwoofers is the best value for the money. And that’s because they’re so versatile and durable.

Having said that, if you quickly want to know what to get, we recommend the Pyle PLPW8D. Nothing beats down the price and performance of this subwoofer. So make the most of your time and energy with these perfect 8-inch subwoofers. This way, you could test out great picks and work your way towards becoming an audiophile.
