The calculator below is useful in determining the total impedance of speakers in parallel. Ok…. Just run the mono center channel output of your preamp to the amp’s right or left channel input and connect the speaker to its corresponding output. The speaker selector switch simulators presented here demonstrate how speaker selectors deal with speaker impedance and power distribution. From what I understand, the Ditton 15s are 8 ohms each and as they’re 2-way speakers you’ll have to use them in parallel. Any idea how to wire the 40hm speakers and does there need to be a negative wire connected to the crossover? I’ve already got a 4 channel amp installed and it performs beautifully…. Hi, I'm hoping to get some advice on setting up 2 speakers + 1 subwoofer on a 2 channel amp. The negative connection for crossovers is usually a common connection and goes back to there also, so it’s the “same difference.”. You can also see from above that really cranking the volume takes a lot of power! Question regarding selector switch: can I combine the L&R input and again combine the L&R outputs and distribute to each zone? and one neg.). https://geoffthegreygeek.com/testimonials/gabriela/. RCA (line-level) connections are preferred, but this should be fine also. Power on the amp and stereo and play a track through the CD-player or head unit and have a listen to your new high-powered speaker setup. You will need 2 of them to get you 4 channels. They do work, though. Glad I stumbled upon this informative article. The difference is how they behave when music is present when they’re connected to a musical amplifier of some sort. more power out the xls215 speaker, and find an interesting article So, I used a multimeter to test the resistance of various pairs of the pre-wire with speakers attached to the ends outside (the ends coming out of the wall were clearly red and black for both speakers. Remember to connect the lounge room speakers to one switch so they can be turned off when you only want music outside. As to the amplifier, the connect amp could work although I think it is only 55 W per channel which could be a tad low depending upon how loud you do want to listen to the music. For example, if you have 16 ohm speakers and the stereo is rated for 8ohms, adding a 2nd pair in parallel would give 8 ohms. Sometimes the amplifier is installed in a ventilated cupboard so it is never seen nor touched. Switch the input mode on the amp to 2 channel. a series resistor (around 2½ – 5 ohms) to restrict the minimum impedance of the speakers circuit to this value. In addition to the basic 5.1-channel system, a variety of speaker systems can be configured by changing the “Amp Assign” link settings to suit the application, such as 7.1-channel systems, bi-amp connections and 2-channel systems for multi-zone playback. If you need to wire more than four speakers, particularly in a commercial installation, see the article on Distributed Speaker Systems. To see how the power is distributed by the different types of speaker selector switches, see my Speaker Selector Switch Simulator. Hello Henry you can find info on how to use more speakers in parallel but still do so safely (safe Ohms load seen by the amp) here: https://soundcertified.com/how-to-add-resistor-to-speaker-to-change-match-impedance/ i got a 2x50 watt amplifier(4-8Ω). :). Thank you very much Marty, Hello Geoff, I have qty 4, 8 ohm 8 inch speakers ran in parallel. This will happen regularly if you watch movies or TV and listen to the sound through your HiFi amplifier/speakers. Without you I would have never figured it out. Example volume produced by a typical speaker at different power levels: So as you can see, doubling the amount of power you can drive a speaker at does not mean you’ll double the volume. Connecting your TV is not as hard as it looks. This article logically shows the relationship between amplifier power, SPL and loudness. Hoping you can help me with some application. That looked like some sort of mix-up, but I tried it. I can figure out how to make any speakers fit (although something that fits on the existing 10” woofer mounting pegs would be nice. This... How much do you need to increase the gain of an amplifier to make it sound twice as loud: 3dB, 6db or 10 dB? Loved the example images as well. So my thoughts are the following: Is it possible to wire four speakers to a 2 channel amp if i run them in parallel? And also there’s a similar setup that, although for car amps, is the same general thing. Hey Marty…… Brother I have a serious question for you and I pray you will reply sometime before I get off work today….. cause I need to do this when I get home this evening…. If you’re very particular about things like crossover phase impact on the speakers/sound or want the ability to use your own crossover settings (inside an amp or receiver, instead of the ones inside the speaker enclosure), bi-amping lets you have that. The result is a strange and poor sounding stereo. channel on the Amp. I realize that you’d rather keep the existing wiring harness but the truth is that it’s not worth the gamble. Obviously, the protective mechanism has kicked in. You can have a look at the Kenwood 1177524 (below $200) and also the Velex VX-502 (under $100). Crossovers are designed to work with a fixed speaker load so changing that affects the crossover frequency and therefore the sound. What I think is that I could leave the subs paralleled and run them to their own individual channels for a 2ohm final load with 200w per sub. If your stereo is labeled by the manufacturer as being “8 ohm speaker compatible” or similar, that means connecting lower impedance speakers can cause excessive heat and possible damage very quickly. You might have a bad cable, prohibiting the speaker from playing any sound. 5.1 channel audio (e.g. For a sample of the type of speakers selector switches available, here are links to Amazon’s range in USA or UK or Australia. It increases a few decibels (dB) for each speaker added. You may want to connect 2 speakers to one amplifier without individual switching or volume controls if you: The recommended speaker impedance ratings are usually listed above the speaker wire posts. ... Do phone chargers and Ipod chargers draw power when not connected to their device? That’s a bit of a vague question so I’ll need more information before I can answer it. If not it’s possible that each pair of speakers are wired in series for a total of 4 ohms to the left & right channels (if the factory radio only has 2 channels and not 4, that is). I recently bought some speakers and was having trouble understanding the correct way to wire them. You might be able to ask for more info in one of the Lexus owner web forums as they’re very knowledgeable. You could just use some speaker wire or other wire to make your own if you can’t find yours. Thanks in advance. But I have no more rca outs on the back of the head unit… AM radio is mono (monaural) unlike FM or CDs which are stereo, so it might be hard to tell. These units rely on you probably not needing to run all four sets of speakers flat out at the same time. If you wire 2 speakers in a stereo with different polarities (for example, one has positive and negative wired as labeled, and the 2nd speaker has the opposite) an interesting thing occurs: they’re out of phase and some sound cancels out. Hi Rob. To use three 8Ω speakers in parallel and keep an 8Ω load, you’d need roughly a 16Ω resistor with a power rating of ~1/6W the power of the amp channel in series with each speaker. This means they have a switch (normally on the back panel – but sometimes inside) which allows you to tell it you are connecting 2, 4 or 8 pairs of speakers to the one amplifier.
