Hi.
I have 8 speakers Bose rated 10-200 Watts/ channel rated 4 to 8 Ohms. 1EC 100W Continuous 6 Ohms. I need an amplifier for them with two zones. I bought Pioneer A10 but it blew up straight away. I need to connect six speakers into one zone and 2 speakers to second zone. Any help would be much appreciate :-) |

You have to wire the 6 speakers in series/parallel to keep the total impedance reasonable, then it will run on just about any amp.

This. Also connect the 2 speakers in series, most budget amps won’t like the 3 ohm load if you connect in parallel. If all this is baffling to you, google is your friend. Edited by TMH Music - 20 March 2018 at 2:08am |

Thank you for your advise. Honestly I've spend hours on google but this is like magic to me.
I spoke today with a guy from "Richer sound" and he said there is no way I could connect 6 speakers to amplifier and that I should definitely not connect in parallel. I just don't get it. Sorry. The thing is, at the moment I have 6 speakers connected to one channel (directly not parallel) and 2 to the other one. It is and old Technics and works well but it makes noise when changing the volume up or down, that's why I need to change it. |

If you have six speakers connected to a Chanel, that is effectively parallel. Speakers connected in series is 'Daisy chaining' them. What you need to do to parallel/series is divide them into pairs. The wires for each pair are connected plus to plus minus to minus. This is a parallel pair. Do this with each pair. Now consider each pair as one speaker. Daisy chaining the three pairs is plus of first pair goes to amp plus terminal. Minus goes to plus of next pair, then minus goes to plus of 3rd pair and minus goes to minus amp terminal.
Essentially, parallel halves impedance, series doubles it so combining them you get to an impedance the amp will work with. |

the way they are connected is:
Zone A - three speakers are connected to the right channel and three to the left channel. All plus are together and all minus are together. Zone B - one speaker to the right channel and one to the left channel. Edited by a2212 - 20 March 2018 at 11:50pm |

Sorry, you didn't say they were connected like that. You previous post said 6 connected to one channel.

Sorry my mistake.
So Shall I keep them as they are or shall i split them? Please help :-) Edited by a2212 - 20 March 2018 at 11:52pm |

3 on each channel is abit of an odd number. Parallel will probably stress the amp but series and you'll loss power. Maybe 4 channel amp?

Not what I’d call a budget solution, but for the ultimate in control, this would do nicely and be dead simple to wire up, 1 speaker per channel!!!!

What sort of noise when turning it up or down? A crackle?
If so its probably a dirty volume pot and its easy to clean them with some contact cleaner. Easier than getting a new amp. |

Thank you for all your help. I'll try to clean it then :-)
