I have an AQHDC315 d1. wired to a AQ 1200.1 at 0.5 ohms. I am thinking about getting a second 1200.1 and bridging them. The question is will making this upgrade be significantly louder to the ear. I know its hard to say because it always depends on box, setup, installation, etc. but I am just trying to get an idea.

Significantly? No.

what would be some advantages of adding the second amp?

None at all, why would you want to run way more power than your sub is rated for?

DJ at audioque has told me that the ahdc3's can take about 2000 daily.

You agreed to follow these terms, please do so. Daily has no logical meaning.

Either way my recommendation stands. It would be a waste of money.

strapped at .5 ohm i dont think the amps will handle .25ohm daily. you could rewire to 2 ohm and get about the same power now just be a little easier on you electrical and the amps.

yeah, I was planning on running them at 2 ohms. Right now it seems like I have to push it into a clip to reach full output. I don't do this but it just seems that the sub could take alot more.

It may, but if all you're doing is pushing the driver further into power compression without actually giving a noticeable difference, why bother?

Ideally, you'd see a 3dB gain, and anyone who's competed in SPL will tell you that in real life the actual gain is much less. Your ears aren't that sensitive.
