Is it ok to use an amp rated at 4 Ohms and speakers at 8 ohms and why or why not?
yes you can you will have to wire up the speakers in parallel because with 8ohm it gives too much resistance and the amp will produce unwanted sound i.e. low volume.
If an amplifier is AC 220Watt and 12 DC so up to how many watts or ohms speakers you can use on it?
Your question doesn't fully make sense. Let me see if I can answer part of it. If your amp puts out 220 watts, the speakers should be rated for at least 220w, or they may be destroyed if you turn the amp all the way up. Watts are a measurement of power, in the case of speakers they are rated for how much power (watts) they can handle. Ohms is a different thing altogether. Ohms are a measurement of resistance to electrical flow. Amps are usually rated to work with certain impedance level speakers (4 ohm, 8ohm, 16ohm, etc.) the lower the ohms, the harder the amp works. I know it seems backwards but it isn't. each amp is different so you would have to read the amp's spec sheet to see what they reccomend. I have no idea what you are asking for with the "12 DC" thing.
What is better 16 ohms speakers or 8 ohms speakers?
It depends on the application. If you have an amp that is stable in 8 ohms per channel, then 8 ohm speakers will work best. However, if you wanted multiple speakers on that channel you could use two 16 ohm speakers.
What is the cost of a 3 watt 8 ohm speaker?
the basic operation of 3watt 8ohm speaker
Can you replace an 8 ohm speaker with a 4 ohm speaker?
Only if your amplifier is capable of driving a 4 ohm speaker. Some have a switch on the back to select 4 or 8ohm speakers. Details should either be printed some where on the back of the amp or the instruction manual
What size amplifier for two kenwood 10 subwoofers?
That will depend on the subs power rating, and how they're wired. Since I don't know which model subs you have, I can only give you an example and not a definite answer. Let's assume that your subs are rated at 100W RMS @ 4 ohms. If you hook them up in series, you will then need an amp capable of delivering a minimum of 200W RMS @ 8 ohms. (more would be better, say 250W @ 8 ohms) If you run those same two subs in parallel, you will then need an amp capable of delivering a minimum of 200W RMS @ 2 ohms. (again 250W would be better) Hope this helps! The wattage of the speakers MUST be more than the amp. Otherwise you can potentially blow the speakers. The impedance of the speaker MUST match or be more than the amp Otherwise you can potentially blow the speakers. Ideally you want more than enough power in amp and speakers than your highest listening volume. An over driven amp introduces distortion. If speakers are wired in series then there is more resistance you half the wattage but double the impedance. So 2x100w 4ohm speakers in series are 100w at 8ohm. If the speakers are wired in parallel then there is less resistance you get double wattage but half the impedance. 2x100w 4ohm speakers are now 200w into 2ohm Most car amps are 4ohm (home hifi usually 4 or 8 ohm) therefore to add 2 10" subs you would need 2x 8ohm and wire them in parallel to half the impedance to 4ohm. Many car sub woofers are dual 4ohm voice coil. This means you can wire a single speaker unit as 2ohm, 4ohm or 8ohm and this then means you can run sets in parallel or series as you see fit. heathcnc here again: I made the assumption of car audio and didn't consider the home audio/theatre possibility. I apologize. I completely agree with these two statements as applied to a home audio/theatre situation. "The wattage of the speakers MUST be more than the amp. Otherwise you can potentially blow the speakers." "The impedance of the speaker MUST match or be more than the amp Otherwise you can potentially blow the speakers." However in car audio, the amplifiers are of a different class and are far more flexible and user-configurable. This is why I always recommend running an amp that is more powerful than the speaker it is driving. That way you can set that amps gain lower than full power(an option unavailable to the user on home equipment). When configured correctly like this there is very little chance of harming your speakers.
SHould you use your CD player or power amplifier to wired to 6 by 9 stereo speaker?
the electrical impedance/resistance will not match. Home speakers are 8ohm and 6X9 car speakers are 4 ohm the speaker would work, but would not last long if played at high volume.
Which subwoofer can I replace for the 2001 Lexus gs300 is it 4ohm or 8ohm?
its a 6ohm sub in the stock location. if you are going to replace it you will need to purchase a good amp. the stock amp does not have adequate power to power any other sub. 10" Kicker comp subs make a great replacement, and get an amp that is half the RMS power input of the sub. make shure that you are reading the AMPs RMS power output.
Can you hook up an mp to a stock stereo?
Yes you can. First, determine which type of signal input is required by your amplifier, RCA inputs or (+/-) speaker wire. If it's only RCA inputs and your stock stereo does not have RCA outputs in the rear of the unit, then you will have to convert each speaker wire pairs to RCA with a converter, then go to your amplifier. If your stock unit does have RCA out, then just use an RCA cable and connect the signal from your stereo to your amplifier. Then simply follow the instructions from your amplifier to connect your speakers depending on if they are 2ohm, 4ohm, or 8ohm, etc. PS - make sure you properly ground your amplifier to either chassis or directly to the negative on your battery. If you create any large amounts of resistance or have extra wire hanging around, you will get ground loops and EMI problems and hear engine noise from your speakers as you accelerate. Good Luck
Please answer. Could you use a 4ohm mixer with two 8ohm speakers at 150w each?
At that kind of audio power level, it's probably not a good idea to work your amp intoa 2 to 1 mismatch. The possible consequences are: > heating the speaker cables, >lousy fidelity out of the speakers, and distortion on peaks, > getting a lot less powerout of the speakers than you expect, > damaging the power output stage of the ampif it's solid-state (transistor) and doesn't have protection against a mismatched load.Technically, you could connect two identical 8-ohm speakers in parallel to the same4-ohm output connection on the amp, and all the hardware would be happy with that.But that leaves nothing on the output to the other channel.
What is the power handling of 5 inch 30watts 8ohm woofer?
You stated 30 Watts - that is the power handled. What else could it be?
Will two 4ohm subs running series and one 8ohm sub running parallel work together maintain a 4 6 or 8 ohm load if not how will the subs work together with a single monoblock amp?
4 Ohm subs wired in series gives an impedance of 8 Ohms. 2 4 Ohm subs wired in series, wired with an 8 Ohm sub in parallel gives you a final impedance of 4 Ohms. Speakers wired in series raise impedance, speakers wired in parallel lower impedance.
What type of transistor do I need to replace an NPN D227 G-615 It takes a 9V battery input at the emitter an IC's output at the base and the collector drives a 8ohm 0.2w speaker.?
Answer The D227 is a general purpouse NPN transistor and not realy critical, one of the following, is ideal replacements for the D227 transitor BC337, BC635 and BC637 There is an error in the question, a NPN transistor's Collector is always connected to the positive of the supply and not the Emitter, an easy way to remember it "the collector, collect the current (stream of electrons) and emit it at the emitter". It is correct if the speaker is connected between the positive of the battery and the collector, although it can be connected between the emitter and the negative but for many reasons it is not good practice.

yes you can you will have to wire up the speakers in parallel because with 8ohm it gives too much resistance and the amp will produce unwanted sound i.e. low volume.
What is 6ohm in amps?
Ohms is a measurement of resistance between the amp and speakers. Most home audio is 8 ohm, if you run 4 or 6 ohm speakers you cut resistance down and get more power out of the amp. Say your stereo is 100X2 @ 8ohm, if you use 4 ohm speakers you should get 50% more power BUT the amp is working twice as hard and can burn up.
