Low End, Done Right

A subwoofer is only as good as the box it lives in and the way it is tuned. We design the enclosure around your vehicle and your taste, match it to the right amplifier, and dial it in so you feel the music without losing clarity. From a clean factory-style upgrade to a full custom trunk, we build it to last.

What Goes Into It

More Than Just a Bigger Speaker

The Enclosure

Sealed, Ported, or Custom

The box shapes the sound. Sealed is tight and generally deeper, ported is louder. We build the right one for your music and your space, sized correctly so it performs.

The Power

An Amp Sized to Match

Too little power and you will not reach the subwoofer's efficiency band. Too much makes it overheat. We match the amplifier to the subwoofer and wire it with pure copper so it gets the clean power it needs.

The Tune

Blended, Not Boomy

Loud is easy. Good is the goal. We tune the system so the bass fills in under the music instead of muddying it, and so it does not rattle your trim apart.
