i need some help connecting my pa system....

[Dj-Nando]

i have a QSC RMX4050HD amplifier so i want to use my four subwoofers with it
2 cerwin vega EL-36B 8ohms each
2 JBL MP255s 4ohms each

what would be the best way to connect them

There isn't a good way to do it, but since the amp is OK for 4 ohms, I would wire one Cerwin Vega in parallel with a JBL on each channel. The JBLs may be louder than the Cerwins. That would put each channel at 6 ohms so it should be safe for the amp.

So i will be using the amp in STEREO MODE or would i be able to use it in MONO MODE

I guess, if you wanted to do a bridged mode, then you would put a Cerwin and a JBL in series and the other two in series. Then put the two series sets in parallel. That would give a 6 ohm load.
I would probably use the amp in stereo mode and if you only have a single subwoofer signal, I would split it on the input to the amp.
