Geo Pro E Pro stereo gripes and improvements

So I mentioned in another thread, the guy who walked me through my Geo Pro G19FD pickup seemed clueless about how to use the Furrion sound system. Thanks to this forum, I was able to explain to him how to switch sound from outside speaker to inside speakers (you change the balance, which you have to know how to access from the menu.) BTW, I have the Furrion DV7100, manual is available online.

My trailer is wrapped up for the winter, but I'm already thinking of changing things for Spring, namely the way they wired this damn stereo. I'm guessing they wired the mono outdoor speaker to one channel, and possibly parallel wired the two indoor speakers to the other channel. Does this sound really stupid to anyone who knows anything about sound systems? If you are inside the trailer, you are only getting sounds from one channel (across both speakers, yay!!!) and outside, you are only getting sounds from the other channel. So if you have a recording of two people singing, one recorded left channel and the other on the right channel, what do they expect you do do, stand in the open trailer doorway to hear both???

So, separating the two channels to each of the indoor speakers is simple enough I hope, just run wires from each speaker to respective connections on rear of stereo plug. Now the question of powering the single outdoor speaker.

I would have to install some sort of speaker selector switch to select between inside and outside. Still not rocket science.

But how would I feed both L and R channel speaker output to the one speaker? From my initial research, it is not as simple as connecting both left and right channels in parallel to the one speaker, this could be bad.

Any of you audiophiles have any ideas?

I replied about this in the Flagstaff thread. See the DV7200 model. Appears to be the unit we should have had originally installed since it solves the issue with two speaker zones, but maybe wasn't ready yet.

So this model is not even out yet. What's going to be our work-around? This is a cheapo unit to begin with, don't want to be spending more than it's worth.

JP, the new unit is now available on the Lippert website https://store.lci1.com/dv7200-stereo-system. 110 bucks plus shipping. That is option one which will allow all stock speakers to work properly

Option 2 is installing a speaker selector switch, and running a 2nd pair of speaker wires (the L channel) to the outdoor speaker, and replacing it with this one https://www.crutchfield.com/p_917FS4...yABEgLgm_D_BwE
Which will make things sound much nicer outside, but with the spacer they sell to make it a surface mount and the speaker selector, you're talking about 250 bucks for that option. The speaker I linked to you connect to both L and R channel wires, it is unusual in that regard.

Stereo

So to hear both tracks you have to keep going in and out the door? WoW ! Maybe some engineer had exercise in mind when they designed this system. Hmmmmmm!

Engineers should be forced to use their product before they are allowed to release a design as stupid as this!

I would simply check your wiring first. There are lots of threads here where the factory simply loused up the wiring. Pull the unit out and check how it's wired.

so they connected the interior speakers (both!) to the LEFT channel, and outdoor speaker to the RIGHT channel, making you use the balance control to change between outside and inside. Brilliant!

Thanks for the heads-up Kris. I ordered the DV7200 from Lippert.

I'm pretty sure I've seen the DV7200 installed in some new trailer promo materials. Not sure why Furrion isn't making it more generally available. It doesn't seem like much of a technical leap from the DV7100.
