Product Description

Right size, right sound

Here’s a big bass breakthrough for truck lovers. Alpine engineered their SWT-10S4 10″ subwoofer to go behind your seat, and sound especially good in the limited space of a truck cab. This deep-sounding, high-performance sub works well in shallow enclosures that’ll fit behind or under the seat in your truck. A “high amplitude” surround allows more cone travel than a regular sub, so the SWT-10S4 can push more air and play louder.

Airflow ensured

Subs get hot as they play, and the heat usually gets vented away via a port in the back of the sub’s pole piece. Alpine recessed the pole port and added cooling air vents on the sides of the frame, allowing you to use an enclosure with an inside clearance of as little as 4-3/16″ without blocking critical air flow. An SWT-10S4 will work well in either a ported or a sealed box, so you can get your favorite kind of bass tone, boomy or tight.

The power it takes

For top performance, you’ll want to pick an amplifier that delivers between 300 and 500 watts RMS at 4 ohms. This single voice coil, 4-ohm sub will draw the maximum output power from a subwoofer amplifier when used along with a second SWT-10S4 in a system. If you’re planning on running a pair, look for an amp that delivers between 600 and 1000 watts RMS at 2 ohms.
