Please note : These are recommended starting points for tuning. ln-vehicle measurements should be made to optimize the crossover for speaker placement and vehicle acoustics. Because of vehicle acoustics, the u se of equalization will be required to achieve flat frequency response characteristics. Individual results may vary.
