1994-2004 Ford Mustang Sub Box Convertible Upfire Ported


1994-2004 Ford Mustang Sub Box Convertible Upfire Ported­­

This Ford Mustang Sub Box is for the 1994-2004 Convertible. The Ford Mustang has a small trunk already and when you throw a convertible into it, the trunk space pretty much disappears. This is one of my designs for this car. This is the up fire design and gets the most airspace that you can fit into this trunk while still being able to fit in the trunk opening. This box is 1.6cuft and has 6 1/4″ of mounting depth so most 10s will work and 8s are no problem. If there is anything that you would like feel free to ask and I will get it done for you.

This box is made out of 3/4″ MDF and is fully carpeted in matching trunk 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.

These cars have the convertible hydraulics under the convertible top and if this car has the Mach system in it, there are factory amplifiers under there also. I would try and mount the amplifier in the trunk somewhere. If anything is put under the convertible top it could potentially damage the top.

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.

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.
