running 2 different types of subs?

i have somebody that wants to install 2 4 ohm svc's with 2 4 ohm dvc's. Running them off an audiobahn hcq2300 300rms x2 @4ohnm, 600rms x2 @2ohm, 1200rms x2 @1ohm. If I ran the dvc parallel = 2ohm then wired it in series with the svc it should be 6 ohms per channel. Or does the two channel amp see both channels as one parallel. What i'm asking is will the amp see two channels @ 6 ohms ea. or one channel as @ 3 ohms.

Thanks

I wouldn't do this... It CAN be done, and it is perfectly safe to do so, but your output will not be the same from each pair of woofers.

To answer your question, though...

It will depend on how you wire it.

If you have (2) 6 ohm "sets" as I will described them, wired in parallel, you will indeed present a 3 ohm load to the amp, BUT if your amp will be bridged, the amplifier will "see" 1.5 ohms per channel. Being an Audioblah, it will run hot, with FAR beyond acceptable distortion levels, and may or may not even run continuously, without activating it's protection circuits.

Of you put one 6 ohm "set" on each channel, then your amp will "see" 6 ohms.

The safest way I can see (and only going by the spec's you have provided) in this situation, would be run one "set" of one SVC and one DVC, with all three voice coils wired in parallel, for 1.33 ohms, and wire one "set" to each channel of the amplifier, and leave the amplifier in STEREO MODE... DO NOT ATTEMPT TO BRIDGE IT!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

so you think the less of two evil's would be to run the subs @ 1.33 ohms per channel vs. 6 ohms per channel.
thanks a bunch for your input.

I have installed that model, if you intend to run it 1.33 ohm you may want to invest in a fan. It will run very hot. The one I installed was wired to 1 ohm as audioban claims its stable at, fthe amp fried itself eventually. Maybe thats why they chrome their amps so the eggs don't stick to them haha!!!!!!

Yeah, it seems to be a pretty big bulky piece of you know what. I think I'll try running the subs @ 6 ohms per channel. Thanks again for the help.

You might not want to run the amp at 1 ohm.. or maybe you do. But you could always run each DVC on just one of the voice coils giving you an even load on all four speakers. 

Parallel them together for a 2 ohm load on each channel. Bridge it down to 1 ohm if you want.

Just keep in mind that you will cut the power handling in half on the DVC's by doing this.

Once again...power handling is cut by 15-20 percent

I got this one for you nouse
