Default Amp/Sub Question

Hi all,

Currently in the process of planning a new boot setup for my '99 Celica 140
and I need a couple of bits of advice.

I want to use two of the Audiobahn 12" Flame subs, as they're going to be
mounted with the magnet outside the boxes to show off the speakers a bit.
Has anyone had any experience with these subs at all? They seem quite
reasonably priced for the performance they claim and their looks £90 for the
AUD-AW1251T which claims 400watt RMS or £105 for the AUD-AWC12T which claims
500watt RMS. If anyone has experience with the sound quality of these
speakers I'd be interested to know... I'm not bothered about huge SPL (not
gonna be entering any sound-offs or anything) although I want it to be
vaguely impressive when the boot is popped... but quality is quite important
to me.

Now this is the bit that has me confused, as I'm not totally sure about how
all the ohmage and stuff works on these things! The subs are both described
as having 'dual 4 ohm, 2ohm or 8ohm operation'. I take it dual means that
they have dual voice coils? Does this mean they'll be seen by an amp as
being two speakers? so, in effect, four overall?

When I was looking at single voice coil subs, I'd been advised that a
monoblock amp could run two subs from the same output, each getting half of
the power (but obviously no left/right channels). Could I run two dual voice
coil subs from a monoblock amp? I'm particularly interested in the Kenwood
KAC-PS810D because it can be controlled directly from my Kenwood HU... this
claims "1 x 1600 Watts MAX Power @ 4 OHM. 1 x 1000 Watts RMS @ 1 OHM. 1x 800
Watts RMS @ 2 OHM. 1 x 400 Watts RMS @ 4 OHM". Would that be ample to run
two of the Audiobahn subs?

Sorry for the massive post! Hope somebody can help and that I can return the
favour with something I understand eventually :-)

Thanks
