sub question
ive got a single 10 subthump box, on their site it says that it's air space is .99. I really want to get an Image dynamics IDQ 10", but the recommended air space is .3-.60. should i not get this sub?

the sub box claims seem to be a little inflated. i think you are looking closer to .8 (fej may be able to give you better insight on this though) you could aways fill up some space in the box to get it down to .6. use some scrap wood and liquid nails in the box and you'll get rid of the .2 cf quickly

also never heard of liquid nails...i'm def going with the image dynamics...
but if it is recommended 250W/max 500 and i plan on pushing 400w, will i be pushing it too close to its limit?

are you saying that the amp is putting 400w rms or 400w peak? if you're pushing it with 400w rms then you'll want to turn the gains down but i'd say you will be fine. cdt subs i've never heard anything about. i have cdt components and love them but i'd be blowing smoke up your .... if i said i knew there subs were good.
liquid nails is just a contractor adhesive, you can get it at any hardware store in a caulking or squeeze tube. it's used for subfloors, paneling, and stuff like that. It's what i've always used to seal any sub boxes i made

We had a big discussion about actual airpace and the subthump seemed to calculate out to approx .77ft^3 useable airspace. From that you would have to subtract woofer displacement of approximately .07 or so (check ID site) which leaves you about .70 or so. Should function pretty decently and I would try it before making any changes (IE adding wood to displace air ... without uniformity I would think that would be hard to measure what you actually took out of the box .. but that is just me).
I am very happy with my IDQ 12" that I am running with 250 watts RMS to it. It is not hard to fill a vette with bass by any means.
I could get into the whole headroom thing .. but to keep it short you will be pusing that IDQ just fine with 400 watts RMS. Keep the gains down and don't try and play a 20hz tone at max volume and you should have no issues
As long as you are not sending a clipped or distorted signal to your subs and asking them to work too hard or play too high, extra watts is usually an OK thing. The sub will almost NEVER see 400 watts at any time anyway.
