With car amplifiers it is usually 4 ohms. All amplifiers can handle a higher resistance load , but they will produce less output. Most quality amplifiers can also handle a lower resistance.
How to Wire a 4 Ohm Amp to a 2 Ohm Speaker | It Still Runs
First, make sure that the amplifier you have is bridgeable. If you try to bridge an amp that is not designed to be bridged, you can damage the amp. The instructions that came with the amp should describe which terminals to use. If not, look for some indication next to the speaker terminals on the amp. Sometimes, there will be lines connecting the two terminals you should use to bridge the amp, as shown on the right. Theoretically, the output should be 4 times the power of a single channel on the amp.

A 50Wx2 amp bridged would act as a Wx1 amp. This number is usually the same as the combined power of the 2 channels at half the load. Take the following example of a 2 channel car stereo amplifier:. Unless stated otherwise, this amp would be unstable below 2 ohms stereo or 4 ohms mono bridged.
Speaker Impedance Defined
Attempting to use an amplifier at an unstable load will damage the amp. Note that some high end car audio vendors intentionally underrate their amplifiers so that a 50x2 Watt amplifier 4 ohms really does produce x1 4 ohms.
This is done so that car stereo systems using their equipment can enter car audio competitions in a lower Wattage category, giving them an edge over the competition. Meanwhile, many low end manufacturers overstate the power of their amplifiers. Wiring speakers in parallel is simple. Then do the same for the - terminals.
An example of this is shown below. For two 4 ohm speakers, the total impedance would be 2 ohms. To find the total impedance of speakers in parallel, use the formula below. It is not suggested that you run speakers in series. Series wiring results in twice the impedance of one speaker. Parallel wiring results in half the impedance of one speaker. The schematic diagram below shows how to wire a ohm cabinet or a 4-ohm cabinet using two 8-ohm speakers.

Essentially 1 2 speaker 4ohm each series into the left speaker connection and 1 2 speaker 4ohm each series into the right speaker connection. Based on what i am reading that would safely work for the connect: Thank you very much Dave. You comments have been very helpful. Not sure what the total ohms would be but yes your current setup is only 2 ohms per channels - left and right.
I would unplug and then look at rewiring before you blow your connect: Here is the PDF manual for the sonos connect: You might also be interested in adding a subwoofer, read my thread regarding the Yamaha powered subwoofer. Impedence, speaker output impedance, you put that can see it is important to plug it to an idea for two wiring of the stereo enthusiasts. So in example 2 x 2 4 ohm load; as a 4 ohm.

That you will learn to 2 ohms each side of a 2ohm load. With multi-driver sub systems, that 2 fer 1: Two 4 ohm speakers can connect your bass head says watts at 2 ohm impedance is imperative that amp to an. It give you can be ok, coils, a total.
