I have a 2000 4 runner (limited) and was hoping to get a custom stealth type box made that way my box will be out of the way. The wheel wall is 7 inches so what kind of sub would you suggest that will be thin enough to work in a stealth box?
You could go with a 10" Alpine Type R - Shallow, which is their: Model: SWRT10
It is a shallow mount and is significantly thinner than their standard subwoofer, and I have gone through many subwoofers, and really like my Type R's. But this is all just personal opinion.
