Thanks for the input. Anybody else want to chime in? The other option they gave me was a custom box with one front facing woofer. They told me I should put the rear armrest down for good sound. I am inclined to go with the JL boxes because of that. I aint looking for audiophile quality or anything, just a nice bass boost.
Any other comments/experiences?
