Please understand that this is a refurbished subwoofer.

The sub may have scratches, blemishes and will not look 100% brand new.
We rebuild a previously used working motor with a used frame (unless a new frame is requested upon purchase), and install brand new parts inside (coil, triple joint ring, spider, cone and dust cap).
The subwoofer may or may not have a motor boot. 

The subwoofer will function just as new and comes with a 30-day guarantee against build defects.

It will take on average 1 week for a refurbished subwoofer to be built and shipped.


If you place an order while the product is on backorder, wait times may be extended.

Once your order is placed, you will receive a confirmation email. No other updates or emails will be sent until your order is completed at which point you will receive an email with tracking information.

    Bought 2. Was over budget. Haven’t regretted it once. They can take a pounding for hours on end and the bass is clear. And a bonus feature is they look freakin sweet!

    P.s. if you’re questioning the name, yes they are in a semi truck. Also, 158 db out of the port.
