Amp v Speakers - Ohms impedence mismatch?

The safety cut out on my amp keeps engaging - I'm wondering if it's the combination of speakers? The amp is rated 8 Ohm, the Ruarks are 8 Ohm, the centre 8 Ohms, but the rear Pures are only 6 Ohm. I rather thought the amp would cope, but I can't find anything else to explain it. The amp is on a specialist hifi unit (Custom Design Milan 5 +) so I'm trusting it's ventilated sufficiently.

Any ideas?

The amp's manual/rear should reveal if the amp can cope with 6 ohm speakers. Remember this is a nominal figure anyway so as long as you don't abuse them, the amp should cope. There might be a switch or menu setting to alter it to the lower ohm setting.

I would start by checking the speaker wiring to ensure no stray wires are causing shorts. I would then connect each pair of speakers and source one by one to try and identify the culprit.

Thank you! I will check the wiring carefully - the rears are wired into the walls so not easy but will check each end.

twist the 2 ends together at the one and get a cheap £5 tester from maplins that will do you and just test the other end to see if there shorting out if you want to go further get someone who knows more and get full IR test on the cable.

Or have you tried using the back speakers on 2 channel stereo and see if they run ok that would tell you the speakers are fine on the amp
