I have a 2003 Exec 406 with the factory fitted JBL amp in the right hand side of the boot. Does anyone know if you can connect a sub woofer to this? I haven't stripped back the boot lining to check yet.
Sadly I've learned today there is no interface lead available to fit another stereo (the last of the 406's that don't have the JBL amp factory system could use the PC99x44 VanBus interface)
