Buying Guides
Size and space
When purchasing an under-seat subwoofer, the subwoofer's height is an important consideration. It is critical to confirm that the subwoofer can accommodate easily under the vehicle seat. Before purchasing a subwoofer, make sure there is room under your vehicle seat for it.
Power handling
Power handling is the measure of how much power a subwoofer can handle without producing distorted audio. Look for a subwoofer whose power processing capability corresponds to the strength of the amplifier in your vehicle. Higher power handling subwoofers will create stronger, cleaner bass, but they require a strong amplifier to operate them.
Enclosure
The enclosure is the case that the subwoofer is housed in. While some under-seat subwoofers have a container built-in, others need an additional containment. The subwoofer's audio clarity will depend on the housing you select.
