Rx-v1800 with check sp wires problem,narrowed it down to the center channell speaker which is 8ohms the rest of the speakers are 4ohms center speaker checks out fine on other receivers,could the ohm differance be the problem,please help,thanks Adam

hi if it was me I would use the 8 ohm more stable...cheers

It is important, most car speakers are rated at 4ohms, you can run 8ohms but only one per channel, there will be a slight drop in volume using 8ohms but it would fine.

You are correct

spks in p = lower than the rating of one

spks in s = greater than the rating of one

so 2 x 8ohms in p = 4ohms

and 2 x 8ohms in s =16ohms

Make sure that you do not connect too many speakers to the amp, and try to stay as close as possible to the amps specs.

Hope this helps, thanks for using FixYa

If you are sure that the speaker wiring is correct and connections are good, then:

• Check the input and output connections are correct for each source.
  
• Check that the input mode is not set to DTS or Analog - rotate the input selector to the source and the press the input mode, set it to Auto.
  
• Also check that the front speakers to be used are selected A or B (or A+B).
• If there is an optimiser microphone supplied with this receiver, ensure that it is not still plugged in.

Hope one of these solutions work for you.

Hi...
Without a huge mess, I would suggest one of the multi-speaker selectors that partsexpress.com sells or a similar item.
Just put "speaker slector" in their search engine.

If youre going to 8 other rooms..you might try a couple of wireless speaker systems too. They work in stereo and ....no wires

Stereo sound requires two speakers per room. One for the right channel and one for the left channel.

There is an internal short that is being detected. This is probably a defective output transistor that is somewhat sensitive to heat. This should be a straightforward repair with a parts cost in the $20 range. Add in the local labor rate for the total cost.

Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...

If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.

If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....
