Audison Amp question
Amp is the 1.400 model.
In the manual I found a paragraph that states "the connections are in parallel" when referring to the A&B subwoofer speaker wire connectors. I am hoping this means that if I set my subs (Kappa 122.7 X 2) to 4ohms (which they are set at now) and hook up one to each of the connections provided, the amp will knock that down to 2 ohms.
Keeping my fingers crossed that I am understanding things correctly because firstly, I want the amp to see 2ohms and secondly it would save me pulling the subs out of the box and fooling with them.
The manual also mentions something about "If you bypass the subsonic filter only the right connection will be amplified". Does that make any sense to anyone?
Eventually I would like to get 1ohm out of the amp, but I'm unsure how to do that with my current subs. Maybe set the subs to 1 ohm, wire them together to get 2 ohms, and hook them up to the right connector only? Possibly the amp would knock that down to 1 ohm?
I'm holding off installing it for the moment because obviously I need to read the manual over a few more times. Dont want to hurt the amp by doing something stupid.
This is about the highest end amp I've owned and it has a lot of configuration options that I will have to learn.
Thanks!

They are DVC subs, BUT they have an "idiot switch" on them. The switch can be set at either 1ohm or 4ohm.
I didnt even know that (or care) when I purchased them. Was more interested in the quality and power handling capacity.
Thanks!

ok from reading the manual - it looks like a dual 2ohm coil setup!
With two dual 2ohms sub - the outcome can either me this:
Rockford Fosgate® - Woofer WiringWizard

First, thank you for taking the time to reply. appreciate it.
My question still remains on the amp though.What does the manual mean when it says "wired parallel internally". I THINK it means if i hook up one sub, to each speaker connection on the amp, and the subs are set to 4 ohms, the amp will "SEE" a 2ohm load total because the amp itself is wired parallel internally.
Let me explain. The Infinity Kappa 122.7 subwoofers have an impedence switch on them. A real switch, similar to a light switch. Slide the switch one way and the sub is set for 1 ohm impedence. Slide the switch the other way, and the sub is set for 4 ohm impedence. The sub has ONE set of connectors only, the switch saves you the trouble of wiring up the 2 voice4 coils.
I have already had these subs hooked up to another amp (parallel & bridged) so I get that part pretty well.
Its the amp I am unsure of.

My friend has the same amp, and he operates it as just another amp. Nothing tricky to it. Whatever impedance your subs are wired to, thats what the amp will see. All you have to do is wire subs to 1 ohm, and plug them into the amp.
On the other hand, I dont know what that "idiot switch" is, cause I never saw it before. Bottom line, do not worry about amp's internal bridging or whatever, if your subs show 1 - 2 -3 -4 ohms, whatever, thats what the amp will see, you plug in 2 ohms, you will get 2 ohms, tha amp will not half that impedance.
And I know what you mean about this amp. Audisons has unarthodox set of settings on the top, you just press buttons in and out. But after a little while everything starts to make sense. I looked at it, and I did not see anythying different in terms of connecting the subs. Just plug and play - really. You'll get a hang of it.
btw, this amp has decent output only at 1 ohm. At 2 ohms, it is barely pushing, and you'd have to jack up the gains higher, but it doesnt like it, and starts to distort a bit. What I am saying, that this amp and your sub combo is not a really good match. Other than that, awesome amp!!!

Sasha, that pretty much is what I wanted to know, thanks. I can live with the 600 or so the amp will put out at 2 ohms for now.
The plan is to pick up another 2 Kappa subs, one more Audison, strap the amps together and wire the 4 subs into 1 ohm. That will give me 1800 rms divided between 4 subs. The 4 subs are capable of taking about 1400 rms so as long as I dont go insane with the gain, I should be OK.
Why you ask? Well, I have the room in the car, I want to design a 4 sub enclosure, and lastly because you HAVE to stop upgrading somewhere and for me, this would be enough.
I am really looking forward to playing with this amp. When it comes to car audio, I am only beginning to understand things, however I know quality when I stumble across it
Thanks again!
John

Idiot switch: 
Also, if the Audison "sees" whatever I give it, then I will set the subs to 1 ohm, connect one to each connection and that way the amp will be driving at 1ohm which is what it likes correct?
Just means I have to pull the subs again and flick the switch.
Yay

that would be wrong there john, the amp would see a 0.5 ohm load(1.400 means mono block, not a 2 channel), I would recommend switching the subs to a 4ohm load, and then one to each, leaving you with a 2ohm final(in theory) The amp just makes it a lil more easy to wire up 2 subs!! (it will take some guess work out for a newb thats all). At least this is what im gathering!
