Superb fit out Brent, quite envious as I'd love a similar set up. In particular the port side sub is very tidy in that location with no enclosure fabrication required.
I would like to emulate but the H190 (which I have) looks to be a bit more tricky due to different internal design.
Bow speakers in the H190 could be upgraded easily in enlarged (if required) factory holes, no worries there.
In the front of the cabin however the factory speakers are fixed into a carpeted ply panel which runs across two bulk heads. This means the speakers are in free air (not enclosed) which will never produce good audio performance.
I have spent a few evenings using fibreglass to make mouldings of the area behind the ply panels with a view to fabricating custom speaker enclosures for each side. This looks somewhat quicker/easier on the DIY websites than in practice
If anyone else has done any mods to the front speakers or sub installs on an H190 I'd be most interested in details and/or pictures.
Will post some pics of my efforts if they are worthy at the end of construction.
