I was thinking about building my own custom box for under my back seat but i didnt know if there were special dimensions that work best or something?

also, if i wanted to port a box, how do i konw what size of box to do it and how to route the port?

 

You have to visit the sub manufactures website or check the owners manual for the sub. Most all subs have required air space to make them perform at their best. Sealed enclosures are often much smaller than a ported box and offer a tighter sound compared to vented.

 

Most of the times the manus are actually wrong....

You really need to get a hold of someone who knows how to do the specific box tuning.

 

i just talked to the online chat at crutchfield and they told me what kenwood suggests for their box sizes for ported and sealed. the sealed specs for sealed box matches what i have right now in my hatchback box. so i guess i will try the ported one to see if they were right...if not, i will rebuild.

 

What kenwood sub? Ive tried Kenwood specs on a few models before... It was just okay.

 

i have the KAC-6202. but i plan on upgrading soon so i am not sure if i will build this box yet or not. are all sub boxes around the same size? im planning on building under the back seat so i dont have much room to go bigger but i think i am going to do a seat lift so i thought that might give me enough room to do a ported box.

 

Thats an amp not a sub.

 

oops

that is the amp i have though...but this is the sub i have...KFC-W112S
