2003-2011 Mazda RX8 Sub Box Ported


2003-2011 Mazda RX8 Sub Box Ported

The 2003-2011 Mazda RX8 is an impressive performance car but like most vehicles, its seriously is lacking in the stereo department, even with the factory Bose system. This box goes in the trunk and fits up snugly against the back wall and has a built in trim panel that fills in the voids to there aren’t any gaps. Pretty much it makes it look like it came that way. This great looking car needs to have an equally great looking stereo system. This box is 1.57cuft and has a mounting depth of 8 1/2″ and will hold a pair of 8s or a single 10 nicely. It can also work very well for a single ported 8” sub so if there is anything special that you would like to see done, feel free to let me know and I will make it for you.

This is a ported subwoofer box. Ported subwoofer boxes 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 double the bass of a sealed box with the same subs. 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 box will be what you want.

This is our ported design. This design is for maximum airspace and the airspace of the box can be reduced if desired. Our ported boxes are designed according to your subwoofers 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 box as needed. We tend to tune our boxes deep, 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.

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.
