When it says to use over 8 ohms speakers, does that mean u cant use 8 ohm speakers or does that mean u cant go under 8 ohm speakers?

It means that you should use 8 ohm speakers for best quality. These are the usual you'll find.4 ohm speakers are available but normally used in a car.Speakers over 8 ohms are not usually available.

you can use 8 ohm speakers,however if you use main and remote speakers they must both be 8 ohms or higher. if u use 2 sets of 8 ohm speakers the amplifier sees it as 4 ohms {speakers are in paralel} anything under 4 ohms will shut the amp down. even playing amp loud it may go in to shutdown when it sees 4 ohms.

Use 8 you'll be fine. If you use 6 or 4 you will potentially trip the excessive power limiter and the amp will shut down. If you limit the volume on 4 ohm, it will work. But, if you over drive a 4 or 6 ohm load, it will shut down and you'll have to shut off the amplifier and turn it back on.

It usually means 8 ohms is the recommended speaker impedance. Using lower impedance speakers like 4 ohm draws more power from the amp and can cause the amp to overheat. But generally in quality amps this will only be a real concern if u constantly blast music close to maximum levels. Some higher end brands will say they are 8 ohm but 4 ohm stable meaning they can handle the lower impedance

That means for best sound you should use 8 ohm speakers to match the receiver. Strange things can happen to receiver if using less than or more than 8 ohm speakers. It is not worth the try.

Should be fine if they are 8 ohm speakers. I think RX-A2020 amps are overrated for power but I would not use it with 6 ohm speakers.

The receiver can easily drive 4 ohm speakers. The RMS power rating of 80W applies to 8 ohm speakers, so the power output for 4 ohms will be somewhat greater. You can change the speaker impedance from the default setting of 8 ohms to 4 ohms using the "Advanced Setup" menu as described on page 37 of the owner's manual.

My understanding is 2 OHM is better. I would however recommend you install the amp to get the proper sound that the speakers are capable of. I have not done this but I need to.

Hello NebTheWeb, This receiver is capable of driving 6 ohms speakers. I use a set of Totem Dreamcatcher (4 ohms) and the receiver is behaving great.

You can control as many speakers as you want as long as you match the impedance and power level. I have two 8 ohm speakers on the left and right, connected to the 4 ohm tap. If you don't understand how to figure impedance take a few and research it on the web, it's actually pretty simple. I'm very pleased with the performance of the unit.

Hello. At 4 ohms that amp provide 525 watts. That is plenty so I would just use both channels of your amp, on for each speaker. You would not want to bridge your amp with these speakers as you would then be providing 1550 watts at 4 ohms and would almost definitely blow the speakers. Also if you bridged your amp you would only have one channel. So either you would need two amps, or you would try to daisy chain these speakers and I don't believe that amp will work at 2 ohms.

Hello Popi, I am not sure I understand your question, but I will give you an overall way to work out your speaker needs. An amplifier is rated by its ability to put out a maximum number of watts into an 8 ohm speaker without distortion (typically 2% at most). An amp will drive a speaker at 4 or 16 ohms as well with varying power numbers and volume. It is important that the amp sees an impedance level of 4-16 ohms or it won't operate well (meaning efficiently and possible overheating or shutting down). It is better to have the amp power rating equal to or higher than the speaker rating. An amp overdriven can clip and suffer damage. If you respond with what your amplifier is, mono or stereo, and what it's exact power output rating is I can be more accurate. Are you planning to drive 4 speakers at 8 ohms each?

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

I have not tried this but from the manual it describes utilizing both the A and B speaker sets. If this is similar to the stereo receivers of the 70s-80s, you would not want to use 4 ohm rated speakers as what normally happens is the speakers get paralleled and the resistance/impedance drops to 2 ohms and that the amp would never be able to handle without shutting down. If I remember, I will test this and comment further but everything I have read says this should work with 8 ohm rated speakers.

Sorry! This question exceeds my pay grade. I've always used only 4 ohm, only 8 ohm or switchable 4 to 8 ohm speakers together.

You haven't provided all the necessary information to receive a worthy answer. We understand you want to power a pair of dual 15" speakers at 8 Ohms, but that's all we know. Complete your research by finding out the power handling ability and capacity of the speakers. Then, look again at the outputs that the amp is capable of. Your answer is then looking right back at you.I assure you this: Relying upon a bunch of people you do not know for answers to questions like this is going to come at a cost. You have no idea that they know anything about which they speak.

They're 8 ohm impedance speakers. Will work with any receiver or amplifier expecting to see an 8 ohm load.Many 12v amps are looking for a 4 ohm load, which I think is what you're referring to. Some are switchable. You can wire these in parallel to get 4 ohms, but I doubt that would be practical for you, since you'd need to install two pair in order to do it properly. If your amp/receiver is expecting a 4 ohm load don't get these.

Hi, you should have no issues at 8 ohms. Used a dozen of these for an install last year and they sound great, and the moveable tweeter makes a difference

It does not matter, general rule of thumb, is the lower the OHM number on the speakers, the more efficient they will be. In other words, the lower OHM number on the speaker would require less watt output from the receiver. Your receiver can output any OHM number, and the same is true for the speakers.

Should be 8 ohms...not going to see lower then that unless you get the really high end audio stuff. Typically...even still 8 ohms is about the standard.

Hi, Jerry! The manual says to use speakers "with an impedance of 8 ohms or more." The speaker connections are not RCA, they're bare wire connectors with a screw-on type fitting. I hope this helps you out. Good luck. By the way and for what it's worth, we've enjoyed our amp and it hasn't disappointed us at all.
