Since I sold my CR-V, I took the sub and amp out of it so I could use it in my 4runner. The sub is an Alpine Type R and the amp is JBL. The box I made for my CR-V was really unique becuase it fit in the rear spare tire well which was empty because the tire was on the back. I took the original box, cut it to somewhat fit better in my 4runner, then I painted it with some cheap truck bed liner. I then put the amp under the drivers seat and mounted it to the seat bolts. It all really fits in good and sounds awesome! I wish the paint would have looked better on the box, but I'm not looking for looks that much.

Two questions: What would ya'll recommend I bolt or tie the sub box down with? It doesnt fall over in normal driving, but does when I go off-road. Also, Where could I get a 10" speaker grill so the sub doesnt get smashed? Thanks!

 

Maybe you can use bungie cords to strap it to the seat. You can get generic 10" grills all day on Ebay.
