I just installed a new JL 500/1 to go with my 10W7 in the back of my tC. The box is ported and tuned to 35Hz. Can anyone help me out with the amp settings on a 500/1 that are best for a tC? I'm looking for clean bass with some impact. Right now the bass line in the song forgot about dre dies down in the upper range and then goes back to normal in the lower range. It never did that with my old system and im sure its just the tuning of the amp.
