    I posted this in the AMP section but go no response, so i'll try here.

    What setting do i set my amp too?

    Pioneer AX5i-S has 2 settings
    6 ohms
    8-16 ohms

    Front speakers - Canton 360 & 2 X 100
    4...8 ohms

    Surround & Surround Backs - Pansonic from an all in 1 system
    6 ohms

    I've no sub attached, not sure if that makes a difference but obivously bass will come through the front.

    Thanks
    Paddy

    It has to be the 6 Ohm setting on your amplifier.

    The lower the Ohm rating of your speakers, the more they will draw current, so I guess that your amp may put a resistor in the circuit to prevent damage to its output stages.

    Using high current 4 Ohm speakers at the front will probably be okay. I'm sure your amp will just shut down if it isn't!

    I agree with diablo's advice, choose the 6 Ohm setting.

    I have the same amp, and my speakers are 4 Ohms and my previous speakers although supposed tobe 6 Ohms were infact 2 Ohms (confirmed by the manufacturer) The amp had no problem with them apart from heat! The 4 Ohm speakers I now have are fine and again I have confirmed this with Pioneer Tech. The amp is a THX certified, which I know alot of people put the THX badge down as being pointless and another way of getting money etc.... but for an amp to get the THX badge, one of the conditions set by Lucas Ranch is the amp has to run a minimum of 4 Ohm speakers (as most THX speakers are infact 4 Ohms). Pioneer are just being cautious and the avarage impedence of the Cantons is 6 Ohms anyway.

    6 ohms it is then.

    Hayes, so once i have all Canton speakers will i leave it at 6ohms instead of switching back, i was thinking, once i replace the panasonic speakers i'd switch to 8-16 ohms

    Thanks everyone

    Stick with 6 Ohms as the Cantons will still go down to 4 depending on the frequency being played. All speakers impedance change with frequency, the impedence given in the spec's are an average apart from Canton who tell the whole truth!!!
