1 cube per side is a bit large for an IDQ V2 12 with 450W, but it should be fine. They are rated to 350W RMS, and I put around that much or 400W into it ported easily. You may want to add a brace or two to make the box a bit smaller. Past that I think that you would be fine with those.
the specs on a sealed enclosure for these subs is .65-1.0cubes. The box is already together so can't really add a brace, would I be able to use polyfill? Would that suffice? I think im gonna get these subs if the wiring will work out? This is my question, I can wire the subs to a 2ohm load(series/parallel) but when I bridge the amp, won't that cut the load down to 1ohm? I don't think I want to run it at 1ohm, it's probably not too stable at high volumes at that impedance. Am I right or wrong on the impedance the amp will see as being 1ohm mono?
