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.

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.
