Sorry, but there is no 2 ohm amplifier on the market, when you mean the output impedance. The impedance is always 0.5 ohms or less. We don't use impedance matching, we use voltage bridging. Scroll down to related links and look at "Interconnection of two audio units - power amplifier and passive loudspeaker".
Hook your speakers up to the 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.
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.
Sure i have 2 400 watt rockfords connected to a 400watt kenwood mono amp. This statement made by another is true.You can hook up 20 subs to a mono amp; BUT you have to configure the speakers by impedance/ohms. if you hook two 2 ohm speakers to a 4 ohm steady amp in parallel you will soon buy a new amp. if you hook 10 speakers in series you will not even get it warm. Each speaker will also divide the available wattage and will not have a lot of power. Take it to a good shop if you don't know the formula for this. you may save your amp. BMyers Lake city, FL
Don't know how you have subs wired but should be 4 ohm load is what your amp will see.
The sound quality won't be very good
You could with a 4 channel amp. Bridge it to two channels and hook up the two 8 ohm woofers in parallel on the one bridged channel. Then hook the two coils on the dual coil woofer in series with the other bridged channel on the amp.
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.
Not unless the speakers are rated at a resistance (ohms) that is incompatible with the amp. Speakers don't generate power, the rating only tells you how much they can handle. So, speakers capable of up to 270 watts, can certainly handle 125 watts. However, if the amp is not 1-ohm stable and the speakers are 1-ohm, you could cause the amp to cut out and overheat depending on the protection mechanism of the amp.
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.
ONLY if your amp can pull a 2 ohm load! Which is vary few but your more expensive amp can pull 1/2 ohm load
You have to employ the microphone jack on the amplifier providing the signal to the speakers. If you don't have a mic jack on your amp, your out of luck.
