1989-1997 Ford Thunderbird Sub Box Ported


1989-1997 Ford Thunderbird Sub Box Ported

The Ford Thunderbird from 1989-1997 was and still is a very popular car with its good looks and performance. It is no surprise that it is still a popular car. This car has a huge trunk but there is no reason to lose all your trunk space because of a stereo system. This box is a rear fire design with a slanted back so it will fit up against the rear seat and take up very little room. It is 2.5cuft with a mounting depth of 8 3/4” so pretty much anything will fit in here. This box can also be made a little deeper if you want to do a custom ported box, just let me know what you want to do and I can 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.
