first is how u want to run the amp itself ....... the MAX2500 can run in mono (bridged) output or stereo ......... though wat u want to watch is the impedance of the load really with the bridged load being no lower than 8 ohms/1500W (there's reasons for this) and the stereo load where u can have either 4 ohms/750W or 8 ohms/500W so how do u want to run this is first the question ..... all 6 on the bridged output or 2 off each channel (though running 3 would make for complicated impedance load) ..... so u'd run 2 in parallel for a 4 ohm load with 300 watt requirement from the amp and u can drive them to 1.5 times their rated RMS figure so a nice 500 watts :)
Hello Disconnect all speakers and switch ON the set without any input connected, and see whether it heats up. A moderate heat is permissable, but should not over heat. If it overheats without any load or input connected, the set need service. OK.
You have to check the ohms of the speakers all spekers should be 8 Ohms or above. if not it will overload the amplifier at high level. The minium ohms impedence of the amplifier is 4 ohms. If you connect two 8 ohms speakers together then the effective ohms will be 4 OHMS then the amp will handle the speakers. If you connect two 4 ohms spekers together then the effective ohms will be 2 Ohms, this will overload the amplifier. You will be able to connect two 8 ohms speaker to left channel or right channel of the amplifier. Check the speaker spesifiction to know its ohms. Make sure all the speakers have an impedence of 8 OHMS or above
impedance mismatch cud be the culprit. make sure ur speakers are the right ohms for ur amp. most amps are designed to operate on a 4 ohms speaker load on bridge mode. some amps are never designed for bridge mode. so if u bridge these amps u will get less output. u have to be very careful when u make the connections. plus when u bridge two amps for 4 ohms load, the total impedance becomes 8 ohms. make sure ur speakers are 8 ohms. few ohms can make big difference on power amps.
First of all the EXA-3940 is rated at 350watts per channel in to 8 ohms. The 1400 watts is bridged into a 4 ohm load. Second, the speakers can handle 1000Wats peak with an average of 600 continuous (i'm guessing). That tells me that the amp is underpowered for the speakers. The sensitivity of the amp is such that the mixer is overdriving the input stage. That is what is causing the clipping. If you are looking for more volume, you are probably better off purchasing another amp and running them in bridge mode, 1 per speaker cab. Be careful though, not to overdrive the speaker cabinets either.
I hope you are aware that in bridged mode your amp will become monaural (single channel, double power). If you still wish to bridge it:
Switch of power.
Set mode switch behind amp to "bridge" position.
Connect speaker positive to CH1+ve terminal of amp output and connect speaker negative to CH2 +ve terminal.
Be aware that now, in bridged mode your amps output power delivery is 1100 watts for a 4 ohm speaker and 900 watts for an 8 ohm speaker. Make sure your speaker can handle that.

It depends on the impedence of the speakers. Carfull as you could burn up this amp if you exceed the resistance rating on it. Go here on all of the specs of this model of crown amps. http://www.crownaudio.com/amp_htm/xlsspec.htm Good Luck
