If the ep1500 amp is used only down to 4 ohms a side or 8 ohms bridged it is a very good reliable power amp with good tone and power. If you run it into 2 ohms a side or 4 ohms bridged "like the manual says its capable of" it will overheat and let you down in the middle of a gig. I was very upset over their claims of how it can be bridged into 4 ohms because I wanted to run it for my bass guitar setup into a 4 ohm cabinet. It kept overheating and shutting down on me every time i used it, so I was forced into using my other speaker bottom also so I could run 4 ohms a side instead.
At least crown amps are honest and say they can't be bridged into 4 ohms. If you need a reliable power amp that will handle a 4 ohm bridged mode then don't buy this amp. I know alot of amps wont handle this low of a load either but at least they are honest enough to tell you the truth.
It is BS that this amp is 700 watts a side into 2 ohms or 1500 into 4 ohms bridged because it is not capable of running this way. Consider this a 400 watt per side power amp into 4 ohms a side or a 800 watt power amp bridged into 8 ohms. That is the truth for this amp.
