Any recommendations for cockpit speaker set up Formula 353 ..currently one set factory installed Kenwood 6x9's....should I go with sub box under pass seat? cant give up all storage under seat...possibly center only?? or another (& upgrade) pair 6x9's ?? just installed new Pioneer head unit, XM radio, etc.

You can use free air subs under the seat and you will not loose to much space.

MBQUart 6 X 9 speakers would be a great upgrade.
