There is no need to match a 4 ohm speaker to a 4 ohm amp, because there is no 4 ohm amplifier on the market. The amplifier will have an output impedance of around 0.04 ohms. In hi-fi we have always impedance bridging. Zout << Zin. The damping factor DF = Zin / Zout tells you what Zout is. Zout = Zin/DF. If the damping factor DF = 100 and the loudspeaker impedance is Zin = 8 ohms, the output impedance of the amplifier is Zout = 4 / 100 = 0.04 ohms. You see, there is really no "4 ohm amplifier" with a 4 ohm output. Scroll down to related links and look at "Voltage Bridging or impedance bridging - Zout < Zin".

Are kicker L7s good speakers and what kind of amp do I need to power 2-15 inch subs?
Yes, the L-7s are great. For the amp, you first need to find out whether the sub woofers are 2-ohm, 4-ohm, or 8-ohm. Depending on the answer to that question will determine whether or not you'll need a mono amp or a dual channel amp as well as the wattage.
Will using a 2 ohm 1200 watt amplifier be ok to use with three 4 ohm speakers 12 and 2-10?
If you connect three 4 ohm speakers in parallel, the amplifier would see a load of about 1.3 ohms. This definitely could damage the amp if you drive it too loud.
How do you reduce the ohms from 4 ohm to 2 ohm ON A 1000 WATT KICKER AMP MONO BLOCK IM RUNNING 2-15 AUDIO PIPE SUBS IN A SEALED BOX. THIS QUESTION IS FOR CAR AUDIO?

Can you wire four sixteen ohm speakers to eight ohms?
No, you can't get 8 ohms with 4 16-ohm speakers. Here are the possible wirings: +o-+o-+o-+o- all in series: 64 ohms |+o-+o-| |+o-+o-| series parallel: 16 ohms |+o-| |+o-| |+o-| |+o-| all in parallel: 4 ohms .... Well in the conventional way it is not possible. But think of the speakers as load attached to the secondary of some transformer while the primary coil is attached to the amplifier block before (a tuned amplifier type). If we adjust the turns ratio as n = primary:secondary = Sqrt(2):1, then the eefective load on the amplifier would be Reff = n^2*Rp. Now as pointed in the parallel connection, Rp = 4. So, Reff = 8 Ohm.
What is a 3 4 and 5-Channel Amp used for with bass in a car?
With Subwoofers only, you would want to go with only a 1 channel or 2 channel amp, 5 channel amps are designed to power 4 smaller speakers, and 1 subwoofer. Each channel basically refers to a different speaker - if you're using 2 regular left and right Speakers (not Subwoofers), use 2 channel setting, if you have 4 Speakers plus a subwoofer, use 5 channel setting. Make sure subwoofer is tested with the lowest gain/volume.
What ohms am i running if i have two 4 ohm speakers hooked up to my amp vs two 2 ohm speakers?
Don't know how you have subs wired but should be 4 ohm load is what your amp will see.
Will 8 ohm sub woofers work with a 4 ohm amp?
if you put 2, 8 ohm speakers together on the same channel you will trick the amp into seeing a 4 ohm load, it is not advisable to run a 8 ohm coiled speaker on a 4 ohm amp unless you do the above. So if you want to run 2 8 ohm speakers from a 4 ohm amp this will work the best although the amp will need to be hefty as its worse to underpower a sub than overpower it! I have used a 8 ohm speaker myself on a car amp and had no problems but it was not a cheap entry level amp! some amps will take it, others will get hot and enter protection mode. Hope this helps!!!
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.
Can I connect two 2 ohm speakers to the front channels of my amp and then connect 2 4 ohm speakers to the rear channels of my 4 channel amp?
This depends on your amplifier's specifications. i would recommend looking in the amplifier's service manual to avoid disapointment or damage to your amplifier or speakers.
I have a 2 channel nitro amp 2000watts amp and it always gets hot after 10min. it's been hooked it up to several cars and it's the only amp that gives trouble every other amp works fine?
If it's running so hot you can't touch it, in most cases it will be due to either the way the speakers are hooked up or the impedence of the speakers. You can incresse the resistance to the amp to have it run cooler by connecting speakers in series or getting speakers with a higher ohm rating. The lower the resistance (2 ohm, 4 ohm, 8 ohm) the more current flows though the amp making it hotter. Remember if you hook multiple speakers in parallel it will cut the resistance in half. So if you connect speakers that are 4 ohm to the same channel you are running at 2 ohm. Check your amp's ratings.
Can you put 4 ohms into 16?
Sure, If you mean your stereo has 4 ohm output and using 16 ohm speakers. The volume will be reduced somewhat by doing this, but it won't harm the stereo. If you have 4 ohm speakers and stereo is designed for 16 ohms you can do it ,but the amp will run hot and you may suffer damage at high volume to the amp.
Can you run 4ohm resistor to make 4 ohms speakers 2 ohm?
Yes, you can safely use a 4 ohm amp with one 8 ohm speaker, but you will not achieve full power. The 4 ohm amp is designed to supply a certain voltage into a 4 ohm speaker. Supplying that same voltage to an 8 ohm speaker will result in half the power, or -3dB. For maximum power, use a 4 ohm speaker, or two 8 ohm speakers in parallel.
Can you power 8 ohm speakers with a 4 ohm amplifier?
Yes, but you won't get rated pwer. Best is to match the speaker to the amplifier.
Can you use 4 ohms speakers and 8 ohm speakers on the same amp?
The short answer is yes, the long answer is maybe. Example: my Toyota's stock CD player says on it specifically, ''4 ohm speakers'', the stock speakers, however, say they are 6 ohms and they measured on a volt meter at 6 ohms. Certain higher end car audio speakers are 2 ohms but are designed for 4 ohm head units and 4 ohm head units can power 2 ohm car speakers. 4 ohm and 8 ohm speakers will work, however, different ohms can (but not always) cause different volumes out of each respective speaker. If your equipment if really old or really crappy it might get fried or if it is modern and of good quality it might get fried if you run the amp at the higher end of its output (high volume). Short answer, you will be fine just don't ask the amp to work super hard. Medium answer, I wouldn't bet more than a few hundred bucks of audio equipment on it and don't stress the amp. Long answer, its complicated and always best to match ohms even though the ohm rating is an average and 4 ohm speakers can present ohm loads of way less than 4 to over 10 depending on their output at the time. Also if you ask different people you'll get different answers.
Can you put an 8 ohm resistor in parallel with an 8 ohm speaker to make your amp think there is a 4 ohm speaker conected and if so will it change the sound or frequency?
Why should an amplifier think it is better to have a heavier load? Use the 8 ohm speaker. If your amp has a 4-ohm output you can strap a pair of 8-ohm speakers in parallel across it to match impedances. When impedance is matched to the amp, maximum power transfer happens. A mismatch doesn't let maximum power get transferred. The sound of speakers that are matched in impedance with the amp will be the same as the sound of mismatched speakers at low power. At high power (high volume), you can end up with some problems. Talk to your local audio guy and get up to speed. Take a couple of cold drinks into the store when things are not busy, hook up the audio person with a beverage, and then open your ears and pay attention. You'll learn a lot.
Can you hook up two 8 ohm svc subwoofers to a one channel amp?
If you connect two 8 ohm speakers to the average car amp, then yes, probably. Most car amps can handle a 4 ohm load, which is what it would be.
Can 8 ohm speakers on a 4 ohm amp damage them?
Sorry, there is no amplifier with an output impedance of 4 ohm on the market. Scroll down to related links and look at "Interconnection of two audio units". Look for an amplifier and a loudspeaker.
