I wont to connect more speakers to my Sony MHCRG590 hifi but it keeps turning off!!?
I have a Sony MHCRG590 hifi and iv got some floorstanding speakers id like to connect to the system with the standerd speakers aswell these floorstanding seakers are 200 watts 4-6 Ohm and everytime i turn it up the hifi turns off. how can i do it so it all works?
Answers:
Actually, a lower impedance (say 4 ohms) will draw more current than speakers with an impedance of 6 or 8 ohms. The lower the impedance, the more current required from the amplifier, and seeing as current is where cheaper amps start to run out of grunt, that may be part of the problem.
By the way, I wouldn't mess around randomly with wiring speakers up, as you can short-circuit your amplifier, which could damage it permanently.
Loudspeakers are said to have an impedance in this case, rather than resistance, because impedance is effectively resistance which varies with frequency, whereas resistance is constant regardless of frequency.
If you're connecting the second pair of speakers in parallel with your original speakers, that will lower the impedance even further. For example, if you connect together the '+' wire on, say, the left speaker of both new and original pairs of speakers, and plug them into the left '+' terminal on your amp (and then do the same for the '-' wires on that left pair of speakers), that's connecting in parallel. If you connect a pair of 6-ohm speakers in parallel, as far as your amp is concerned, you've connect a single 3-ohm speaker to it. For two four-ohm speakers in parallel, it's 2 ohms, and so on. Asking a midi or mini system to drive a 3-ohm load is a bit optimistic, as the amp's power supply almost certainly won't be beefy enough to supply sufficient current.
As one of the other posters said, you can try connecting the speakers in series. I recommend you do a search on the web for parallel and series connection of loudspeakers, as this should clear up any confusion and avoid the risk of barbequing your amp. Connecting in series adds impedances instead of dividing them, but then voltage rather than current becomes the important factor. Again, your amp may not be up to the task of producing an output signal of sufficiently high voltage, but hopefully I'm wrong - fingers crossed.
amplifiers shutdown if they are asked to play too loud. Many will overheat, with bad consequences.
The more ohms you have the more power they need. Ohms is resitance.
Over all, you will not get more that 470 watts of power out of that system. More speakers does not make the system louder. It will just move the power around.
Your overloading the amp not sure how to fix it though. Other than buy a bigger amped setup.
the protection circuit is operating.. the only way, is to wire them in series from the speaker end.. only using one set of wires into the amp for each channel.
