2nd sub install position on R7 surf

[Dcraiggerhart]

Hello. I searched, but couldn’t find. Has anyone installed a 2nd JL 10” sub on a ‘21 R7 surf? Currently have Premium sound, with JL M 600/1 monoblock and the JL 10” sub behind the drivers seat. If so, can you provide pic of the 2nd location, and any info on how you routed wiring? Thanks. David
