4 channel class D amplifier on sub bass duty?

Hi mate, 4 ohm driver comment, was for OP.

Have always considered what 9001 would be like, driving 2x 4 ohm drivers per side..

Ive got a "cheap" class d here that will spank all of the above driving 4 x 8 ohm drivers, might not give you that nasty distorted sound you get from a VZ though...  Just because you tested a couple of lab clones years ago that blew up does not mean there is nothing out there that will do the job.   

even top flight multi-channel amps like powersoft x series benefit hugely by mixing loads - on an X8 i would recommend 50% mid / high channels and 50% bass/ sub. Same with X4's. 

Im always amazed how small a proportion of the overall budget people allocate to their amplifiers. Large speaker stacks may get more interest, but without the right amps behind them its all rather pointless.

There seems to be a few people saying "i tried xyz 4 channel amp and it wasent ideal for running heavy bass on all channels, so all other 4 channels must be the same..."    Not all 4 channel amps are built the same, some have higher long term power capability vs burst capability than others, eg the 44m20 supply will give about 3KW long term, the JAM Q10 will give over 1KW per channel iirc so over 4KW total, from memory i think it was around 1.4KW per channel i will check, this new 4 channel im testing has a supply rated at 7KW for a 16K amp, its not the only factor, burst / storage capability and output stage efficiency also matter, the point im making is not all amps are the same.

The original question was can a budget 4 channel amp power 4 x 4 ohm 700w bass drivers,  there are many out there that can, you dont need a powersoft K10 / K20 for that...  

Im often amazed at how people think they must have a expensive (normally Powersoft) amp to do job (like power 4 x 700w bass drivers) when there are many very decent budget alternatives,  more expensive does not equal better if its overkill for the application, And yes CSG i am selling amplifiers, much like you are selling powersoft amplifiers :)

TB, which lab copies are you selling?

In terms of original manufacturer/distributor?

Any pics of innards?

EDIT:After 2x years waiting, research, I once bought 4x FP10000Q lab copies, as they were some of the higher specified/better built.

PSU on one of them still died, powering 1X Fane 18XB, on 1x channel.

So that was the end of trying Lab copies for me.
