The Best 8 Inch Subwoofer Buying Guide

Listening to an audiophile who happily discussed sound quality to us, we had our ears full of audio physics jargons that would baffle people without familiarity or in-depth knowledge about it. Apparently, even having familiarity with the terms got us nowhere!

For many of us, we could leave the audio physics to the experts. All we could understand is the richness of the sound quality. But, there are some things that we should understand to help us choose which one is the best for your jam. Let’s take a look at some specs that are relevant, useful, and easy to comprehend.


The wattage rating you see on the box of a subwoofer determines how much power your subwoofer can handle. However, this is the peak performance and anything that operates on peak performance for long periods are bound to overheat and blow off.

Root mean square (RMS) means how much power your speakers can handle continuously. If you frequently drive long hauls, you may want to consider this instead of the peak performance.


High speaker wattage will require a higher power supply. Make sure that your amplifier can support your subwoofer. In the event that it cannot, you will need to upgrade your amplifier too.

Intended Usage

Carefully define how you intend to use your setup. Do you play loud music or just mellow jams? A high end and expensive setup may adapt to all types of music. However, if you don’t need it for that purpose, you can save some money by choosing what’s best for your jam.


The best car 8 inch subwoofers can surely make your music a lot more fun. In this selection, Pioneer’s 8 inch subwoofer swooped its competitors with its features and versatility.

This subwoofer can project 20hz with clarity without a problem. Even at low volumes, this speaker gives out rich and deep bass response that can be felt in the air. Although it comes a little pricier than average, it lives up with the quality it claims.
