2 ohms per coil.
two coils in parallel.
2/2=1 ohm

Oh really? Beauty, I thought the Dual 2 Ohms made it just 2 ohms rofl... What a retard I am.

Thanks Kiki!

you'd want the dual 2 ohm XXX. that's how it comes normally.
the coils in parallel give a 1 ohm load, which is what you'd want with either mono amp.

that 85x2 is plenty of power for components as well.

What sort of amps for the sub and speakers should I be looking at?

I found these on the DLS site. Couldn't find prices for these, but I assume they're on the expensive side.

Ultimate A6 Mono Amp - 1200W at 1 Ohm (If I bought this amp I would go with the Dual 1 Ohm Version of the XXX)

Ultimate A2 2 Channel Amp - 85W at 4 Ohms, 145W at 2 Ohms (Would these work for the Components?)

Classic CAD15 Mono Amp - 1600W at 1 Ohm (Same deal as the Ultimate A6)

What companies should I be looking at for quality amps? Elevation has the 1500Wx1, 899$ MSRP?

great system so far, but here are a few suggestions;
look for a better amp to compliment a nice system you have there.
Coustic is ok but not on the level of the rest of the system if you want a good balance.
Aperiodic just takes a lot of time to tune by ear or meter.
Also you lose 3dB compared to sealed in SPL, but very good for driver control. You also need a car with a trunk to use an AP box unless you don't mind cutting holes in your hatch back and venting to the outside, which causes issues with weatherproofing.

that hifonics amp is a bit low rent for lack of a better term as well. for that sub it really deserves a better amplifier. more reliable, more clean power.

it would be to your benefit to save up a little more and go with better power sources.
also consider electrical upgrades to feed these amps if you go this route, and a good alarm system to protect the investment.

No thoughts?

Here's what I currently have.

Deck: Alpine CDA-7897
Speakers: Alpine Type-S 6.5" Coaxials
Subs: Resonant Engineering RE12s(2)
Amp: Kicker KX350.2

Here's what I plan on getting sometime within the year.

Deck: Alpine CDA-7897
Rear Speakers: Alpine Type-S 6.5" Coaxials
Front Speakers: Elevation Audio Concert Series 6.5" Components
Front Speaker Amp: Coustics 360u
Sub: Resonant Engineering XXX 12" Sub (What box is best for SQ? I think Kiki mentioned somewhere that Aperiodic is best, though this seems like it really hard to get right)
Sub Amp: Hifonics BX1605D

This is a long time in the future before I can gather all this, so I have tons of time to shop around and junk. I'm gonna buy the components first though since I have no front stage yet and have the Coustics amp just kicken around. After that though I'm gonna buy a newer car then work at getting the rest of the stuff.
