Need that little extra bass? Haven’t got much space? Look no further.

With a built in amplifier powering an aluminium coned subwoofer and a max output of 300W the In Phase USW10 is a true pocket powerhouse of audio performance.

Measuring a mere 69mm in depth and 270mm in diameter, this unique unit will fit easily in just about any location in your vehicle while still packing a powerful bass punch. You may have to look a little harder to spot it but your search for a compact with impact is truly over.
The USW range of underseat subwoofers have been designed by In Phase in the UK with Pioneer, Kenwood, Focal, Alpine and VIBE in mind. They took the market leading subwoofers, compared stats and designed their own and unique subwoofer to find ground where these subs lacked.
Some of the things In Phase compared was amp power, frequency range, robustness, quality of material and of course price range. In Phase have been developing car audio products for nearly 20 years, from headunits to speakers or subwoofers to amplifiers. You truly get bang for buck with In Phase audio.

Die Cast Aluminium Chassis

No plastic structure here! The metal body is part of a secure and rigid structure, no flexing body when the unit is in full power, this also helps with bass output.

Big power, little body!

Only measuring at 270MM in diameter and 69mm deep, this little sub can fit under most seats. The big power output is still there! 300W peak and 150W RMS.

Aluminium Cone

Metal cones are light in weight and can be really stiff, but they are really robust cones that rarely go wrong. This sub has a damping material built into its cone and spider to ensure a rattle-free performance and deep bass.

Frequency Range

A sub is as only as good as the enclosure it is fitted in, the housing on this subwoofer is specially designed taking into account, space, air space behind the sub and frequency tuning. So the frequency range on this sub is 50Hz to 100Hz
