Every series diagram seems to suggest connecting one speaker with + to the other speaker with -. Hi Paul. In some cases, white, clear, or some lighter color can be used to represent the left channel. So somewhere in the wall R, B, G & W changed to two pair of R, B.) Crossovers are designed to work with a fixed speaker load so changing that affects the crossover frequency and therefore the sound. Sounds great, Anthony! All amplifiers of any type – where it’s a car stereo … So, I tried a standard approach. I’ll go into detail about the right and wrong way to wire speakers and connect them properly to your stereo or amplifier. The problem is you’ll lose 1/2 the guitar amp’s power output across the resistor, but if you’re not needing really high volume it may work for you. bridged to the sub? Hello Kevin and I’m sorry I somehow missed your comment. Ohms rating for the amp, and (3) the impedance (Ohms) of the passive bass modules. Im kinda new to this. I have 2 Rockford Punch subs in a band pass box. You should be able to do that with your amp without any problems. If there are only 2 wires visible I suspect there’s another connector or connection points for the rest. Protection kicked and turned off the receiver as soon as I tried zone 2. I'm looking to run 6.5" components in the front and 6x9 in the back all off the same amp. If it were a 4 ohm amp connecting to a 2 ohm speaker, you could see problems with your amplifier overheating when pushed to the limit. So my thoughts are the following: i got a 2x50 watt amplifier(4-8Ω). Sound quality is not an issue. I realize that you’d rather keep the existing wiring harness but the truth is that it’s not worth the gamble. Although the volume will be similar in all areas, at least it is possible to turn off the speakers in the areas you don’t want sound. Hi Phil. You can also see from above that really cranking the volume takes a lot of power! How many speakers with what wattage can I connect to 200w amplifier? If not, thanks anyway – you’ve answered enough. Changing the speaker to 8 ohms would change the crossover frequency to 250Hz, causing a big “gap” in the sound output. Wiring speakers in series raises the impedance delivered to the … ... Do phone chargers and Ipod chargers draw power when not connected to their device? Hi Marty. Amp has 2 sets of speaker terminals that are connected in parallel internally. The volume on the slave amplifier can be set (as outlined above) and then never touched. Hi Darrin. Keep in mind that changing the total load impedance of an amplifier will increase or decrease the power output of the amplifier. Otherwise, if your amplifier doesn’t have enough channels you could get a fairly inexpensive second amp and use that to drive them or the Cambridge speakers to get enough power. 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. Random question – hoping you can help. As you want to install 6-speakers to a 4-channel head unit, you must have a 4-channel audio head in your car. They ended up with a burned-out amplifier. One channel hooked up to the speaker and one channel not connected. I think the simple solution for you is to use a normal four way speaker selector switch but only use one channel. Hi there. I would start by verifying that the outdoor speakers you’re having problems with are the right impedance for the receiver. A more practical (and a little bit more expensive) way it to substitute the selector switch with a unit that also has volume controls. How to Connect Speaker Wires to Your Receiver or Amp Speaker Terminals Most all stereo receivers, amplifiers, and standard speakers (i.e., ones that are able to receive signals through speaker wire connections) feature terminals on the back for connecting speaker wires. I'm looking to run 6.5" components in the front and 6x9 in the back all off the same amp. Basically, I need to know the product/model/specifically how and what you’re connect to…as much detail as you can share. The resistance value comes from a long coil of wire inside each speaker called a voice coil. Question regarding selector switch: can I combine the L&R input and again combine the L&R outputs and distribute to each zone? This is closer to a daisy chain as each speaker and corresponding single wire forms part of a daisy chain loop. What is your thought on using bass blockers. You can connect four speakers to a two-channel amp through in-series or in-parallel connections. If this page has helped you, or perhaps even saved you paying for a technician, please consider a donation to Geoff to encourage him (and appease his wife) for the many hours he puts into this website. In the following diagrams I will only show the wiring for one side of a stereo amplifier, let’s say the left side of the stereo. These units rely on you probably not needing to run all four sets of speakers flat out at the same time. Speaker selector switches can use various techniques to allow multiple speakers to be connected to the one amplifier, namely: All these methods allow multiple speakers, but at a lower volume than using just one speaker. I want to connect 2 50w speakers (8Ω) to 1 channel. Hopefully I’ve given you more understanding about how to connect speakers and get the most enjoyment out of your system. This way, the volume for the speakers for the workshop is controlled in the workshop. There will always be a different case for every person to use this method to wire their speakers because some people might have two speakers in their car, and some might have four. Note the markings above the connectors. Bridged on 2ch. Attaching Speakers in a Series Wire your speakers in a series if they’re less than 8 ohms. You need to know three things: 1. Hi Ronnie. Well, you need to know the impedance (Ohms rating) of one of the voice coils on the original subwoofer, which you can find by measuring it with a test meter set to the Ohms scale. Hello Shibli. Thank you so very much. The answer to this is the 4 speaker and 2 channel amp configuration which has become quite famous these days. 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. Thanks for the feedback. The second is to biamp the speaker, an option that could result in better sound. 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. I like to use 50W or higher per channel as a good rule of thumb when buying an amplifier. First of all, keep in mind wiring a 4 channel amp to 6 speakers is not a good practice. How to tell if my 12″ subs are bridged inside the box? For a sample of the type of speakers selector switches with volume controls available, here are links to Amazon’s range in USA or UK or Australia. Can I use the speaker wire from the head unit or from the wiring harness of the vehicle and wire it to the high end of the new amp for the doors and dash…. A separate golden phoenix amp pushing two 10″ JL audio subs. I'd love to help everyone find answers to their questions & enjoy good sound. I am trying to re-hookup two Zone 2 speakers to a Yamaha RX-V665. It is working like a charm. For traditional speakers, you’d use the front channels. I believe I know what you’re referring to. Cerwin Vega calls those “bar jumpers” in a speaker manual I saw (they’re basically just jumper bars). If you could help me do I to wire for 1-2- or 4ohm load? I am running 2 klipsch reference 12 inch subwoofers as well. Hi Marty, and thanks a lot for your reply. Hello Eddie. But it only runs my 2 subs and 2 6x9s in the rear of the car….. You may want to connect 2 speakers to one amplifier without individual switching or volume controls if you: In the first article we saw that a decibel is not a fixed unit, rather, it is a ratio between two levels. Currently in my Ram 1500 I am running an aftermarket hu in which I have front preamp outputs and rear/sub outputs with a setting to switch between the rear and sub. I have had many people over the years tell me it is easy to connect multiple speakers – all you have to do is wire the speakers in series. Image of the rear of a home stereo receiver/amplifier. While this is not as safety assured as using impedance matching, it may suit some installations. If the front and rear speakers are all on separate left/right and front/rear channels from the factory radio, then yes you can use two 4 ohm speakers (in parallel) in the place of each original 2 ohm speaker. Yet, it is often the first (and possibly... Speaker sensitivity is a measurement of how well a speaker converts the amplifier power to to acoustic energy. It is not for music. Thanks very much Marty you as an expert explained yourself clearly so as even a 73 year old I could replace the wiring correctly on my home stereo system. If that’s the case, you’ll need to get some RCA plug to speaker wire adapters and use those to connect it.
