Crest 9001 - 4 ohm drivers

The 9001 should cope fairly well with that load.  I have run them at 2Ohms with 4 18" reflex per channel.  You will need a decent power supply because it will draw a lot of current from the mains doing it and make sure the amp has plenty of ventilation.

I also know people, looking for 9001s.

Any around ?

i would only trust the 9001 for 2 ohm operation have seen one running 4 1850 drivers per channel and the clip lights did not even go off for hours and handles it regularly , due to the excellent limiting behavior, no dead drivers and no amplifier issues and certainly no lack of sub !!!!!!!!

Well that seem pretty obvious,  but for now we have the opportunity (and cash) just for one. We jumped on the occasion as it was relatively cheap.

Could you elaborate why? Is it not stable @ 2 ohms (but the specs & benchhmarks states so)? do we risk damaging the amp/loudspeakers? we'll have a better sound (=more defined) in 4 ohms?
Or just because we won't have heaps of headroom?

I know that things can be better, I'm just wondering if 6/8 scoops out of a void is (as the specs/benchmarks would show) and if not please explain why.

For now we use 3 EV p3000 8ohms style, 1scoop/channel, which would be absolutely fine if we have infinite space and box boys. we had a good price on this one amp which is praised everywhere so we had a go at it. the other idea was to try the proline 3000 (1 for 4 scoops)
The idea is to get most of our scoops, we don't want to underpower'em.

I may begin another thread on this point

EDIT : to sum up, I'm not asking what is the best/perfect solution but if this amp would be suitable for these subs (6 or 8 pd186 superscoops)

What kind of nightmares? What kind of scenarios? I'm very i nterested to know what things we should avoid.

EDIT : I just saw you typed "who knows" so I guess this comment come from hearsay, if anyone here have full failing stories on 2.6/2 ohms I'm interested :)

FYIl we intend to use it on 2.6 ohms stereo but I've read that drivers in scoops tend to have an higher impedence than the nominal one, and that also the infinte 8 was a tank

Also the drivers are rated @ 700/800 Watts contineous so I guess we won't need it to deliver full power of the amp, especially for 6 scoops.

Also, we'll upgrade to 6mm² speaker core speakons (20 meters)

And we we'll use it only on 32A supply, I guess that venues not able to provide 32A don't deserve more than 4 scoops

Also the reason we want to go void (apart from the occasion/cheap price) is that we know personaly people who are going to sell it to us, so we're confident on the amp (we learnt the hard way buying old amp 2nd hand could be risky...).

Anyway thanks for your time man

Not from hearsay, but considering your last statement, nothing else to say to you.

Feel free to take your off topic questions to another thread, as opposed to hijacking this one, with completely unrelated questions.
