Adding a subwoofer, in a very different way
So this post will be my build log for adding a subwoofer amplifier as well as a subwoofer to my Kia Niro LX hybrid.
My primary goal is to add a subwoofer to the stock stereo. However, I have a few requirements that are going to make this build different.
The subwoofer MUST NOT take away ANY cargo space.
The amplifier MUST NOT exceed 315 watts which is equal to the Harmon Kardon premium audio amplifier size.
Requirement or Preference #3
A 10” subwoofer is used.
So how in the world am I going to have a 10” subwoofer not take up any cargo area? Well, I could put it in the spare tire well, but then I would have to put my spare tire and/or the tire tools in the cargo area. So that place is out. After looking and measuring closely, it looks like I can build a custom subwoofer box for a 10” sub to go UNDER the driver seat! Yes, that’s right. A 10” subwoofer under the driver seat.
Since my LX model does not have power seats, there is 6” of height there. Front to back is about 10” and width under the seat rails is a whopping 20”!! So that will leave me with a box of only, about 0.35 cubic feet. That’s not much to work with, but I found a shallow mount 10” sub that has a minimum sealed air space requirement of 0.35 cubic feet. Perfect!
The amp I will be getting has the capability of putting out nearly 700 watts so I’ll have to put my meter on it and turn the gain down so the maximum RMS wattage will be 300 watts, which is more than enough to drive this particular sub.
But before I order the sub online, I want to build the box. After the box is built I will be able to accurately measure the air space and will then confirm that this sub will work. If the box ends up being less air space than what I originally anticipated then I’ll have to downgrade to a single 8” sub that will work in the available air space.
So as progress is made, I will update this thread and will be taking pics along the way.
