are these speakers have a 4ohm for impedence matching replacement-a very neccessary question before purchasing and installment?

Yes, they are 4ohme speakers and really make the sound clear on a stock set up.Another option are the JBL 6X9 three way, as they are really 2ohme, but are rated at 4, although they come at a higher price.I am totally happy with the Rockford Fosgates. I have two Nissan Xterras with the factory Rockford Fosgate sound systems. I hope you find this helpful.

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.

yes 4 ohm single voice coil they are very powerefull i have a 150 amp to them in 4 ohm .ive had them over a year

4 ohms is the modern standard, and these speakers match that standard. Antique car radios (tube electronics, made before c.1965) may require 3.2 ohms. 2 ohms is for specialty applications (e.g., Bose and some "enclosure-less" subs).

I don't own this but am considering this. The manual shows an audio out so you could go into an amp with that. The speakers are 3 ohms and have a jack on the side that would allow you to power a speaker, if you could get or make the same connector that they have. The issue will be the 3 ohm 7 watt rating. typically speakers are either 4 ohms in smaller units or 8 ohms in larger speakers. You will see less volume with speakers with a higher impedence with 8 ohm speakers being only about 1/2 as loud as the 3 ohm speakers that are supplied with the unit. There could be other problems with impedence mis-match but I haven't tried it to know.

The impedance with the high and low range terminals connected in parallel with supplied connectors (recommended default setting) is 8 ohms. The speakers can be driven with an 8 or 4 ohm amplifier. Most receivers are 8 ohms. I am driving them with an amplifier designed for 8 ohm speakers and they sound great. There should sound just as good connected to a 4 ohm amplifier. Basically the impedance of the speaker should be equal to or greater than the minimum rated impedance of the amplifier.

I measured them when I got them and they were something like 2.6. These are designed that way to accommodate OEM wiring, which I smaller gauge than aftermarket, and low powered radios. Installed the resistance is over 3, but that is less than using 4 ohm speakers. Actually, amps get more control, but require more power with higher resistance. That is way home stuff is 8 ohm. In a car power is limited by the alternator output. For matching, look at the RMS Watt rating of the amps and speakers and try to match 75% to 150% of the amp rating. Speaker sensitivity will also be a clue. A 3 dB difference means twice or half as loud. So a proper Watt RMS and as high a sensitivity possible is a good general rule. These are rated at 93 dB so they are better than most. Sensitivity is the measure of sound at 1 Watt power from 1 meter away.

IMO if you putting these on a aftermarket amp get some 4 ohm speakers to be more amp friendly. These are 2 ohm and probably best for factory replacements. As far as what amp to get i am guessing you are going low budget. MBQuart and hifonics make cheap good 4ch amps. Stay away from the wally world stuff and don't forget high level inputs or a line out converter. PAC SNI-35 great budget LOC

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!

No I have not, but if it's a 4ohm rated amp I wonder if there will be adequate power to sufficiently power them (depending on your needs), as these are 8 ohm speakers.

One more thing. If you are planning to use your Samsung speakers from your home theater you might wanna check the impendance of the speakers. Most HTIB speakers are rated at 3 ohms. If that's the case you might s well just buy a whole new system haha. Just saying.

I don't see that being a problem. But I have never tried to run any speakers with that impedance. I did a little research and found this sentence in a post:"Marantz doesn't officially rate their receivers for 4ohms either, but they do just fine with 4ohm speakers. Marantz reps will tell you that its OK with most speakers. A lot of Yamaha receivers are rated for 4ohms, so the 667 would be another option at the $500 price point." I found this on: http://forum.blu-ray.com/showthread.php?t=162749Good luck!

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

They're supposed to be 4 Ohms even though the back says "4/8 Ohms" but in reality they're less than 4 Ohms - a tad under 3.5 Ohms. unless your amp/reciver can tolerate resistance of 2 Ohms which very few can, don't wire them in parallel with an 8 Ohm speaker. I did and it almost fried my receiver.

Absolutely. There might be an efficiency difference between the speakers, however, most 5.1 or 7.1 systems allow you to adjust the offset volume, which only needs to be completed once. If you are simply using these as a set of stereo speakers it want even matter. Also, your ohm rating is higher, not lower. While technically, the efficiency may be lower due to the higher ohms rating, there are so many other factors that this isn't even something to wotry about. Lastly, it would be if the ohm rating were going lower that you might need to start being concerned, however, 4 ohms and above, no. Sean

These speakers are 4ohm rated. You will need an amp that can handle 4ohm speakers. I use a AudioSource Amp 100 Amplifier. It goes for about $120

Yes, I have two pairs of 8 ohm speakers myself, and have had no problem with impedence clipping or overheating. If I'm not mistaken, the impedence can be set separately so the system compenstares for unmatched speakers also.

The manual says the speakers should be between 8 and 6 ohms impedance. You probably would run the risk of frying the output amplifier by overloading it at 4 ohms.

I no longer have this unit. I believe so at 4 ohms but I suggest you refer to Audio Source Tech Support: 1.877.715.5439 or locally 503.914.4688

Oh yes, they should give you all the volume you can take. From the start they sound great and then get even better as they break in. Just keep in mind that their impedance is 8 ohms.
