I am considering ditching my power hungry mtx 225 h.o. and 275x to replacing them both with this http://mobile.jlaudio.com/products_amps.php?amp_id=438

My question is will this be enough to drive my canton 605cs component set and an Image Dynamics IDMAX12 D2 V.1 adequatley?

Use the rears for the comp set, 75 watts is plenty, not sure what the power rating is for your sub, but if it's close to 300 then yes.

What you should really do is get JORDY's C4 DD amp, that will drive anything you can think of and probably for a lot cheeper then the JL. And it's BNIB.

No it won't be enough power for your setup.

Those two amps aren't overly power hungry for their output for a pair of class A/B amps.

Switch to all D-class or at least D-class for the sub if you feel you need something more efficient.

How much are you going to pay for the JL? JL is good stuff, but expensive. You may get a better price with another brand.

Are you going to the Show in April?

Just to add to this, I would recommend using seperate amps for your sub and main speakers. Using a 4ch to run all this isn't going to be the best bet in terms of performance and SQ.

^ It is with Jordy's DD amp hehe

I would tend to disagree with the 4 channel amp statement. If the amp is designed properly you should not notice any effects of having your subs and mids running off of the same amp.

There's only a handful of 4ch amps capable of driving a 1000wrms sub bridged on one side and running a good comp set on the other two channels and of those very few are not going to be effected sonically on the front stage drivers when the sub taxes the power supply for a peak dynamic burst.
Plus he'll need one that is capable of being bridged for his sub at either 4 or 1ohm as he has a dual 2ohm driver.

On top of those two obstacles the original poster wants more efficiency in his choices and a big 4ch class A/B capable of running the IDMax is not going to be as efficient as swapping in a class-D on the sub. I don't know of a all class-D 4ch big enough to drive the IDMax on two channels.

So again I'll recommend going a dual amp route with a class-D on the sub or both for this setup. Efficiency, dynamics/performance, and processing ability being the main reasons.

Why not a five channel then? The JL had enough power to do everything Thrillhouse needed it to do though. My original suggestion was to simply find a similar amp at a smaller price point. JL is a good brand, just expensive. JBL makes a good 4 channel that would be less expensive then the JL, as does Alpine, Memphesis and lots of other companies. The 225HO is not a power house, so each of these amps will give good results compared to what he already has and it would be in one chassis. Last time I checked, Thrillhouse had an SQ car (very good one at that!). I'm not sure what the priority is here, but a 4 channel amp would do a fine job for the equipment he has. Sepreate amps are generally prefered, but not required. I have 5 channel amps in my car, and they do a good job.

Most 5ch amps are really two amps on one chasis. Usually a class A/B on channels 1-4 and a class-D on the 5th (sub) channel.

Actually the 225HO is indeed a little powerhouse. The little 25x2 amp is rated at 400x1 at 1ohm at 12.5v. Actual output on a typical car's operating voltage is going to be in the 600rms range as this amp was already pretty underrated.
The IDMax is rated at 1000rms. I would not recommend the JL listed above or any similar amps as running 300rms to this driver would not be ideal.
