Quesion about boost and power handling.

I'm posting this here instead of the regular subwoofer forum since this is a DIY sub. If it's the wrong place just let me know.

First, my meager setup is a 12" Ultimax in a 2cf sealed box and an iNuke 3000DSP. For awhile the only EQing I was doing was taming the nasty room peaks in the 40-60hz range. Recently I've been experimenting trying to get a little more low end output. Right now I have it at +5dB at 25hz with a Q of 10. It seems fine, no bottoming out or clipping, but I have heard it's not a good idea to boost frequencies using a parametric EQ. Could this become a problem?

Secondly, I'm using the 3000DSP bridged. Again, no problems so far, but I figured it would be better to power it this way at 4 ohms than to use only one channel at 2 ohms. Could this be an issue if I got crazy with the volume, or are the unofficial power ratings of ~1500 watts RMS as inflated as Behringer's specs?

Thanks for any help.

There's nothing wrong with EQ boost, that's what a Linkwitz Transform is. You just have to be sure that you don't exceed either the thermal or mechanical limits of the driver.
