I am about to install 2 2X18" Renkous Heinz Qube sub woofers in a club B&C equipped...
I am some 25-30 meters away from the dance floor and the amplifiers, i have available 4 lines of 2X2.5 mm cables . I could locate the amplifiers one meter away from the subs but the Owner of the club will not do that ...
I have many good same amplifiers available though .... So the question is if it will work better to brake the connection behind the sub and operate 4 woofers distributed 1Woofer for one ch of amplifier . Each amplifier will operate at 8 Ohm load .
I expect less distortion when i am close to the peak less stress in the amplifiers and more total power
Is my estimation correct ?

How much power will be available after a 30mtr run of 2.5mm cable? Not a lot. The average 10mtr 2.5mm spur has 5volts drop at 1kW!
I have run Nexo Subs with 6mm cable over a maximum run of 10mtr. and the power drop in noticeable.
Insist the amplifier is next to the speaker. It is the only way. You will have poor bass otherwise.

John in many of your answers you have made a sport on loosing the target .... As you can tell from my writing i am completely aware of that ....working on it though trying to convince the owner about it
That wasn't my question though

Well, the 4th. line in your post #1 isn't clear. I think you ask: is it better to use 4 amps with one speaker each or all speakers on one circuit using a bigger amp.
I would go with 4 amps, one speaker each. If 1 of 4 fails you still have 75% of bass left. E

I have the ability to drive the subs with one amplifier at 4 ohms each But i also do have the ability to drive the subs with two amps which means on amplifier channel for each woofer ...
