2017 337RLS Entertainment System Mods

[yattr0]

Ok, I'm an retired electronic engineer so this might be a bit over the top. I made a few improvements to the entertainment systems on our 337. From the external appearance appears to be about the same as before but the TCL TV is a bit higher (relative to doors above) and the soundbar below. Plus the addition of a subwoofer behind the lower left door (second picture)...

More to follow...

I also added a fixed side table to the rear theater seating position as is is devoid of any sort of area for things. It is attached to the slide and avoids contact when retracting the slide.

Here are a few of the mod pictures...

All doors off and all side walls removed. The 4 screws mark the fixed mount location (removed)

The view behind the center door, Furrion location

The view down the hole to the floor behind the fireplace. The slides are for the drawer which has been removed. The wood behind the TV wall is where the mount attaches - plenty of room for relocating. The shelfs to each side are the tops of the storage area on each side of the fireplace.

The left door area was restored back to original (wall put back up) as only the left door was needed. Here is left area and all the devices...

I've got beer if you feel like dropping by.

[yattr0]

Thanks, about to have one here...Anderson Valley Salted Caramel Porter aged 6 months in Wild Turkey Bourbon barrels...

[vonzoog]

Ahhhhh, I grew up one county over from those barrels back in Kentucky.

[yattr0]

Nice barrels!
