1993-2011 Mazda B Series Extended Cab Sub Box Ported


1993-2012 Mazda B Series Extended Cab Sub Box Ported

The 1993-2011 Mazda B Series Extended Cab has the space to be used for a stereo system but the awkward floor makes it difficult to just set a sub box back there. This down fire design is 1.75cuft with 7 1/4″ of mounting depth and just slips into place behind the front seats and fires the subs down at the floor. Because this is a down fire design you get the added acoustical benefit but also get some protection for the subs. Since you won’t see the subs, you can still store stuff on top of the box without worrying about damaging them. This box will hold a wide variety of subs with two 8s, 10s or one 12. A single ported sub down fire in this truck sounds fantastic. Let me know what you would like to do and I will get it made for you. The rear seating will be unusable with this box since it sits where the seats would have folded down.

This is a ported subwoofer enclosure. Ported subwoofer enclosures are for customers who want louder, deeper bass with the lower bass more pronounced. Because of the ported design, the bass will not be as tight and punchy as a sealed box, but there is typically double the bass of a sealed box with the same subs and power. A sealed subwoofer box has a tight and punchy bass that is more articulate and more true to the music with a more natural sound. If tight, punchy bass is what you want then our sealed designs will be what you want.

Our ported boxes are designed according to your subwoofer’s specifications. No two boxes will really be alike. At checkout, there is a “Comment” box, please give us the model number of your subs and we will build the enclosure as needed. We tend to tune our boxes low, around 34-37hz. If you have any specific requests, please feel free to let us know.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickel plated spring loaded speaker terminals are mounted on the back of the box and the speaker wires are soldered on for a solid and reliable connection.

Contact Us About Your Options (This is only if your order requires some advanced customization. If you need a customization fee, we’ll let you know).

We use Stinger wire on all of our boxes.
Acoustic stuffing will make the enclosure sound like it is in a larger airspace. It will give your woofer a little deeper of a tone, but will also take away a little from the upper bass. If our enclosure is a little small on the airspace needed for the woofers, then we would recommend the acoustic fill.
Please enter the Brand and Model of the subwoofers you will be using.
