Im planning on running a pair of type r 5.25 components in front with a pair of type r coaxials in the rear off a JBL 80.4 amp. This would run 40 watts rms to each speaker. The problem is the coaxials are only rated up to 35 watts rms. Is this gonna be a problem and am I gonna blow the rear speakers? Any other speaker suggestions if this is too much power?
