I recently purchased a used 2015 Cyclone 4114. The Previous Owner cut the wiring for the main living area entertainment system. I was able to find a brand new system and want to rewire the TV wall using HDMI. I was wondering if there is a diagram for the wiring or just routing location. I am assuming I will have to pull the liner from under the unit. Also was a subwoofer installed in these units as the original Sony DAV-TZ140 comes with the sub?
