Hi guys,So it turns out the sound system has the strength of Dot Cotton. I looked in to putting a couple of Focal IBUS20 flat subwoofers under the front seats as this has been a rather good solution in previous cars. However in the Nismo there isn't enough clearance under the seats. How is everyone else beefing up the performance of the sound system in their Jukes? Any help or advice would be much appreciated, preferable where and how to install a subwoofer.cheersG
