Will they work as mid bass in car doors? say from 70 to 400HZ?

I am planning on running four of these in the doors a '09 VW Tourareg as a midwoofer, I am using a 4 way system and this I only unse from 70 to 400 in a reinforced, freeair door enclosure.Any comments would be appreciated, tks
Asked by: Weyler
Check with the T/S parameters to make sure that this driver works in a free air resonance environment. The other consideration is the design of the driver. It is "weatherproof" on the front side, but not the rear where it might be exposed to water and condensation.
