Are channel a and b separate amps in ST mode? If I hook up an 8 ohm speaker to each (in ST Mode), do I have 8 ohms or 4 ohms?

Stereo mode is two separate amps. You would have one 8 ohm load per side, independent of each other.

Are these home audio or auto speakers? ... Yes... These are good for both home and car. At 8 ohms a car stereo amp might not play them as loud as a 4 ohm speaker but it will not hurt the amp. If you're concerned about getting 4 ohms at your amp just wire a pair of 8 ohm speakers in parallel. Usually the only difference in home and car speakers is the label, although better car speakers may be built with materials that hold up to temperature extremes better than most home speakers. I personally use home and car speakers interchangeably because any good amp will have no trouble running a 4 ohm load.

Thang:Again thank you for your helpful response. I will now shop for a sub, and hopefully complete my system soon. It is a more difficult task than I first thought.I have the Bose single cube speakers that I plan to use, but I am unable to determine the ohm rating of these speakers. Can you assist me with this. I have been studying the 806 manual and the speaker ohm rating is one entry that needs to be input by me. Hopefully I will be able to get things up and running soon. Thanks.Charles

If your amp can handle a 4 ohm load that means you can hook two 8 ohm speakers up per side. That's 8+8 =4 ohm. You Re fine as long as the total resistance of your speakers are 8 ohm speakers.IF you run two 4 ohm speakers per side you get 2 ohms etc.You could also wire the two 8 ohm speakers I a series and get 16 ohms.

I went through a steep and maybe incomplete learning curve when I wanted to add multiple speaker pairs to my setup but I do not believe you have to have speakers to all of the inputs for 8 ohm output. This switch is auto impedance matching. My system is 4 ohm amplifier and I've had 1, 2, 3 and 4 pairs of speakers connected at various times and have never had 6 pairs, the switch has worked great and I use it all the time when I am at home. One thing I would caution on is that while description says that you can use two sources at the same time I've found that you get bleeding from one source to the other side.

No problem at all. Also for future reference, say if you have an amp with four and eight ohm binding posts, just wire the 6 ohm speakers to the 8 ohm posts and rock and roll!

On a 4 OHM output amp. You use one 4 Ohm speaker or two 8 OHM speakers. Example: One 8 OHM speaker + One 8 OHM speaker = 4 OHMs.

Best way is to wire subs together and get a good 2 channel amp that can handle a 1 ohm load. If you call power acoustik they can help but you'll be wiring positive to positive and negative to negative making the subs run at 1 ohm. you're going to have to get one hell of an amplifier to pushall four of those subs. I had a BAMF4000/1D just to push one sub

I have been using these in my home theatre system for about two years and they are 8 ohm. I really like these....they open up after you use them for awhile...awesome speakers for rear surround channels...

This amp puts out a 100 watts per channel @ 8 ohms. Your volume control is in your pre-amp, for difference volume and delays for each speaker. this unit is not a class a, a/b, but act like one. it's a step volume, but stay clear at high peak before clipping. It's best to use speakers with the same ohms, but you don't really have too. This why the separate volume comes in, and most rooms are not perfect. Placement of speakers are more important than the unit that power them....

I'd leave the selector at 8ohm and run the mix of 6 and 8 ohm speakers. It should be fine. The only way you'd run into a problem is with 4ohm speakers, and in that case you should be using a discrete amplifier.

I have 8 ohm B&W; cs1 speakers and use 6ohm without an issue. I'm not sure why they didn't design it for 8ohm

I'm no expert, and don't know what they mean by 4 ohm topology. Generally, the 4 ohm amp would be underpowered trying to drive 2 ohm speakers. Should be ok at low to moderate volume but high volume could overheat the amp. You should ask on a car stereo forum.

Using two 16 ohm would be the same as using four 8 ohm. You would be getting about 30 watts of power to the speakers. That is not much!

from my understanding your speakers ohms should not be lower than your receiver/amp. This will have your receiver working overtime to power those speakers which may casue overheating. For a 8 ohm receiver the lowest I would go would be 6 ohms; I think 4 ohms is pushing it.

If you hook them up to separate channels, your only getting 440watts per size (stereo). If you run it in bridged-mono, and run your two 8ohm speakers in parallel, you create a 4ohm load, which is supposed to pull 3000watts from it. I run two 18" subs with it, and it does pretty awesome. But is it REALLY putting out 3,000watts......? I highly doubt it. Still, a great little amp for the money.

You cant wire two four ohm speakers 1 ohm. If you wire them parallel they will be 2ohms. This amp will power them nicely. To accomplish 1 ohm you would need 4, 4ohm speakers. Basic ohms law.
