Has anyone used the Pioneer shallow mount sub? -
Amazon.com: Pioneer TS-SW841D 8 In. Shallow-Mount Subwoofer with 500 Watts Max. Power: Electronics
Does anyone know if it will fit in the factory box that came with the 10 speaker JBL Synthesis system?
What is the size of that factory box in cubic feet?
Any recommendations on which sub to use?
While I'm at it, what have you guys replaced the other 9 speakers with?
