Frequently Asked Questions

What is the difference between RMS and Peak power?

RMS power refers to the continuous amount of power a subwoofer can handle safely, while peak power is the maximum burst it can take for a very short moment. We recommend always matching your amplifier to the RMS rating for reliable performance.

Do I need a separate amplifier for a subwoofer?

Yes, most subwoofers require a dedicated amplifier to produce meaningful bass. Factory radios typically do not have enough power to drive a subwoofer effectively, so an external amp or a powered subwoofer with a built-in amp is necessary.

What is better, a ported or sealed enclosure?

In our evaluation, sealed boxes provide tighter, more accurate bass and require less space, making them ideal for music genres needing precision. Ported boxes are more efficient and produce louder bass but require a larger box and are tuned to specific frequencies.

Does the size of the subwoofer matter?

Size dictates the physical volume of air the subwoofer can move. Larger subs like 12 or 15 inch models generally produce deeper bass, while 8 or 10 inch models offer faster, tighter transients and fit in smaller spaces.

How do I wire dual voice coil subwoofers?

Dual voice coil subwoofers can be wired in series, parallel, or a combination to achieve different impedance loads. We researched wiring diagrams and suggest checking your amplifier manual to ensure the final impedance matches the amp’s safe operating range.
