I'm upgrading the system in my 2011 SCAB with JL equipment. I'm going with C5 570's front and rear driven by the HD 900/5 amplifier and the cleansweep devices. I want to go with the Stealthbox for the sub but read on several threads here that it doesn't fit under the rear seat ot the SCAB. The JL web site says it will fit '04 and up SCAB. Does anyone here have the Stealthbox in their SCAB or know if it will fit properly? Thanks in advance
