Has anyone replaced the RCA surround sound system?

It depends. How good are you with splicing wires together? If you are comfortable then look on the back of the RCA unit to see if it shows the speaker impedance. If not then look online for its specification.
Now find a unit that has the same impedance and splice the wire. Make sure you splice + to + and - to - (very important).
Now most stereos/DVD have component or HDMI outputs as well as tv having component or HDMI inputs. That would be the easy part.
PM if you have any questions.
Not hard to do.
I completely change my surround sound in my coach with new speakers, receiver and TV. Just took a little time but well worth it. I posted several pics. My new receiver had plug in speaker connectors that were color coded and that made it super easy.

I know how to do it but I'm getting lazy as I get older.

I wish all units were as easy as yours. Most home theaters in a box now have proprietary plugs for their speakers. My new unit had proprietary plugs but that didn't stop me from learning.
I had to cut my speaker wires and add more length because of where I placed my speakers.

All the ones I have found is junk just like the RCA one we have.
The popping I have no idea why it happens but I suspect a bad capacitor on the circuit board.

I don't use it much now because I now have a TV with reasonable speakers that work great. So only when playing DVD's I use it.
Iggy...your speakers are all 4 ohm speakers (the kind used in car stereos) so simply wiring them into any other kind of home unit will fry your new home unit which is almost always designed to work into 8 ohm loads. (nominal). While you can still use the existing wiring....I would suggest that if you find a new home receiver/dvd player...that you also replace each existing el cheapo speaker with an in wall or in ceiling home speaker with impedence off 6-8 ohms rather than 4.
A pair like these would be fine as a replacement...but you can also get big improvements for more $$ from major brand speakers like Polks, JBL's etc.

I was hoping someone was going to find a simple plug in solution. So I can play iPod listen to radio while driving then surround sound while parked watching movies

I can't think of something simple.
Does the iPod have Bluetooth?
If not then look for a receiver that has an aux input and run your iPod earphone jack to it.
Where are you planning to locate your receiver?

mine still pops however I disconnected the sub and all other speakers are working used it for a little while and no popping. All this is over my head. I did connect my Bose Companion 3 series to the TV and have good surround sound using that. Haven't watched a dvd so not sure how that's gonna work now. Guess it should work hopefully with no popping.. Ill let you know.

I think I may try that and disconnect subwoofer. Can't hurt in trying.
Thanks

OK, time for my two cents. Although most surround sound receivers are designed for 8 ohm loads, some can handle a 4 ohm load. I've used my Sony for 5 years now driving Clarion 4 ohm marine speakers.

Why am I using boat speakers in my RV?....Mounting depth. There is less than 2" of space in the Georgetown ceiling before you hit the roof membrane. The Clarions were the only speakers I could find that would work. The speakers you have provided the link for will not fit. Surface mounted speakers weren't an option for me either, because of the speaker placement. Cabinet doors and the right side slide room would interfere with them.

I went to a lot of trouble installing a system that I'd be happy with. In the end, I'm still not 100% satisfied. The 378, and RVs in general, provide too many obstacles in achieving good surround sound.

If I had it all to do over, I would probably just buy a decent soundbar w/ wireless subwoofer, put a DVD/Blu-ray player in the space under the TV (some of you don't have that option) and use the ceiling speakers for music only.

I'm now in the process of trading my Georgetown for a Sunseeker (wanted something a bit smaller), but if anyone is interested in any of the A/V changes I made to my 378, I'd be happy to share the details.

Rod...first...you are correct...my recommendation did not consider mounting depth. The WAY to cope with inadequate depth and still get good sound is to mount a trim ring and mount the speaker to the ring. But of course, individual coaches will have their own issues as you point out with doors etc.
And yes...good sound is difficult in this environment as it is in autos. This is why I didn't recommend REALLY good stuff...it just ain't worth it!
As to 4 ohm speakers (4 of them) working on a conventional HOME receiver...it is LARGELY true that they can damage the output transistors and/or blow the internal fuse. THIS happens when you hook them up as A speakers and B speakers and hit A+B dropping the load to 2 ohms. There are a few receivers that will drive 2 ohm loads but they are generally out of the range of casual RV buyers and would impact your CCC!
It will not generally happen if you hook them up as main and center and rear in the surround sound terminals....or keep them used separately as A or B rather than A+B. Or keep the volume low.
I was trying to keep things simple for the OP.

May I ask WHAT model Sony you have and how the speakers are hooked up? It would be useful to understand your experience since I'm about to become a G'Town owner.
My guess is that the pre installed system will drive me crazy.
