HDC3 - Impedance Rise

[notoriousroc1 10+ year member]

I am planning a build involving Hyperflex 1/0, stock batt (upgrade to odyssey soon), HDC312, RF T10001bd.

The RF T10001bd puts out at least 1000w @ 1 ohm. My plan right now is to get a loaded horn design from Pete, about 3-4-cubes if I recall correctly. Should I order a D1 or D2 Audioque HDC312? If I run it in parallel with a D2, I'll have 1 ohm + impedance rise. If I run a D1 parallel, I'll have a .5ohm load + impedance rise. Which should I order off a stock 80a alternator, stock battery setup for a 2001 maxima. I want to squeeze the most power I can out of that T10001bd, cause I know its not much for a HDC3.

Which coil config should I order?

Imp rise is not a factor with music.

so if i get a d2, there will be no box rise, or any sort of impedance rise? a d2 parallel-wired, will be seen as a 1 ohm load ALL the time?

Get a d2, run it at 1.

Impedence always changes when the sub moves. It will not stay at 1 ohm all the time.

yea i wished...but 'themommyvan' stated "impedance rise is not a factor with music"....that went against everything I've learned before

Impedance is constantly changing, but you don't really have to factor it in for daily/music listening.
