Because as far as i'm aware most or all switch mode power supply amplifiers that are budget or mid-range price aren't capable of their rated power output continuously, most specs are burst specs so i've been told by the Pro Sound Web guys before. They said that only when you get upto amplifiers like the PKE or Crown I-Tech kind of price can the switch mode amps output their rated power continuously due to them having better power supplies.

I like the heavy toroidal amps with lots of capacitors because they're better on subs than lightweight cheap amplifiers.

I never said anything about smps amps. There are plenty of torrodial amps with the beans to get those drivers moving, within the 500-800£ price range.

I think your getting too hung up on things like headroom and underpowering, granted these are important issues, but in real life simple precautions and common sense will protect yourself and your gear adaquately.

For example i use matrix str2400h's to power my 18's @ 4r and they should give 600w per driver (2 per ch) just under clip, and this is plenty to get them properly moving. I havent damaged any amps or drivers doing this even tho im 'underpowering'. Just keep a keen eye on djs and invest in a decent limiter.

I also power my dual 18 subs discreetly.. 1 driver per amp channel, but my subs have 4 ohm drivers in them which makes it easier to fully power them. I don't know if this will help you now but consider buying 4ohm drivers when you reload those boxes, and I'd also suggest you completely ignore any maximum ratings those drivers might have and pick an amp that can comfortably do the continuous rating.

That was pretty much my intention to use amplifiers to power my subs at around or a little over their continuous power rating as I play techno which is as we all known a very highly compressed music style.

According to specs, the q99 has only half the output power of a proline3000. Running it bridged on 4 ohm sub (effectively 2 ohm/ch) is a bad idea. It has been explained time and again how this will put maximum strain on the amp.

If you are really concerned about max power and headroom, the proline would be your choice in this case.

The next question would be, how many prolines do you really need? For the size of that winebar you will be doing, one proline powering two double18 (4oh per channel ) will be overkill.

A crew i'm affiliated with uses three proline 3000 to run rhino scoops, 1x18" per proline channel. They play big venues. Two prolines easily do medium venues. Actually we had a sound meeting recently, in which one guy showed up with a two scoop stack, running both scoops off ONE channel of proline 3000, second channel doing kick. He could keep up well enough.

I'd suggest you try first what one proline can do running two of your subs. Then compare if there is any benefit to running one driver per channel. You might be surprised

I'm using Proline 3000 amps ok because they're capable of continuously outputting their rated power output as aposed to a lot of Yamaha amplifiers which i've heard pro sound engineers say are actually rated in burst not continuous average power output. Plus DSP wise i'll be using either a Driverack PA2 and Drawmer DL441 on the Driverack's outputs because it's supposedly an excellent limiter or maybe if I can get enough money together I might buy a used XTA DP226 because it's a brilliant loudpskeaker management system and also has built in Peak and RMS limiters.

Sorry, i just went off on a tangent looking at other amps. since you were considering the q99 i assumed you might also consider other options.

I love proline and crest pro series, i just hate to carry them

Don't worry about going off on a tgangent it's ok, I hate heavy amplifiers due to their weight but when I buy a sound system I want it to sound as good as it can be and so i'd gladly have very heavy amplifiers if they're gonna provide more continuous power to subs.
