Frequently Asked Questions – FAQ's

Q: What is the hardest hitting 8 inch subwoofer?

Q: Are 8-inch subs any good?

A: Yes, they are amazing as they are not as huge as the large subwoofers. Yet, they work perfectly in smaller vehicles. The best 8-inch subwoofer produces a much better and top quality sound than the average factory speakers.

The biggest advantage of 8-inch subwoofers is that they can save the battery of your vehicle and they can boost your audio system bass too. You can make your audio experience much better with a good quality subwoofer installed in your vehicle.

Q: Which size subwoofer is best?

A: It depends upon how much space you have in your vehicle, generally, subwoofers are the boxes with the driver inside each of them. The driver needs some space inside the box to perform and deliver quality audio. If you have a decent space then a 12-inch driver is good otherwise go for an 8-inch sub.

As the size of the driver goes down the power should go up. So, with more power, an 8-inch subwoofer will sound exactly the same as the 12-inch sub. It’s much better to go for an 8-inch subwoofer with more power if you have a space issue in your vehicle.

Q: How much airspace does an 8” subwoofer need?

A: The required space for an eight-inch speaker is 0.375 cubic feet. By building a larger enclosure you can have more space inside for much better sound quality. A smaller size than the suggested box size will not produce the same audio quality and it will limit the audio quality. If you use the smaller box size than suggested then there is a big chance that you will end up damaging the sub before time.
