i kno how bad audiobahn is for sq. i currently bought soundstream bass enhancer as a test and it works pretty need with my subs. the remote actually tunes the bass. it highers or lowers the hertz, while adding extra bass, of course, u got to tune the amp with the enhacer to modify the bass at first and lower the gain substantially, but with that lil enhancer, it improved my bass up to 25 % in sq and spl. what do u guys think------and yes it still doesnt have great sq(audiobahn) but its deep as hell and has really great spl.
