FAQs: Subwoofers for Cars, Trucks, and SUVs


Do I need a separate amplifier for Soundstream subwoofers?

Most Soundstream subwoofers—like the T5-124 and BXW-124—require an external amplifier. However, powered models like the USB-8P and USB-10P come with built-in Class D amps for easy integration.

What size subwoofer should I choose?

A 10" or 12" sub is ideal for tight, punchy bass in most vehicles. If you want deeper, more resonant bass and have the space, a 15" sub like the T5-154 is a great option.

What type of enclosure works best with Soundstream subwoofers?

Soundstream subwoofers perform well in both sealed and ported enclosures. Sealed boxes deliver tighter, more accurate bass, while ported boxes produce louder, boomier bass—great for low-end-heavy music.

Can I use Soundstream subwoofers with a factory stereo system?

Yes. With the right amplifier and line output converter, Soundstream subwoofers can be integrated with most OEM systems. Powered models like the USB series make this process even easier.

How do I break in a new subwoofer?

Play your subwoofer at moderate volume for the first 10–20 hours of use. This break-in period allows the suspension to loosen up, improving sound quality and preventing long-term damage.
