I own cerwin e715 for 5 years now, originaly powered by a harman kardon 3480 (rated 120watt rms 8ohms) after 2 years when played at high volume, light where dimming on the receiver and i had to repair it .. not sure what was the reason ..
Also runned for a party by a Crown xls 602 (370watt rms 8ohms) and now with a Crest Ca6 (400watt rms 8ohms).. the sound is a lot better with the crest ca6.. better damping factor and less distortion etc etc...
E-715 are rated 8ohms compatible but in reality there are more like 4-6ohms.. as your amp is 4ohms compatible i realy dont think ill be a problem to drive those speakers
