I do not have the RF system...so i think im in luck with finding speakers.
(not to offend anyone here, but the RF system was a ripoff, how can you justify $1500 for a sub and amp)
This is what i came up with:
Polk db960 for the front
Pioneer TS-A1780R for the rear
and I picked up some "slim"
XTC baffles
these are all rated "EZ-Fit" and dont require any mounting brackets.....what do you think?
