Using both ohm options on amp?

[BertThePigeon]

Stupid question time //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif I've tried to find this answer but couldn't. If i have an amp that is... 50 Watts x 4 + 200 Watts x 1 @ 4-Ohm //// 75 Watt x 4 + 300 Watts x 1 @ 2-Ohm... my speakers could be 75W @ 2-ohm and my Sub could be 200W @ 4-ohm. That is how it works right? You can "Mix and Match" ohms of speakers as long as they follow the amp RMS for each?

Just don't go below rated impedance

RMS rating of amps are just a stat, a good starting point to follow. Same as the ratings of speakers. Best not to push either for the continued health of your equipment!

And you can connect virtually any speakers to an amp. Just don't ask for their current draw to be too much (low Ohms) as that can overwork amps and cause their electronic death! Likewise to not power speakers with too much current/watts as that can cause their electronic death! But as I learned, above all else keep the signals clean and low distortion because even at rated powers, a loud dirty signal can burn out a speaker very quickly!! I know, I killed my Alpine SWR-t12 slim line sub with a dirty strong signal caused by bad amp gain settings!

Sorry, I probably should have clarified my question more. My main question is if my 5 ch. amp can power speakers@2ohms and sub@4ohms (mix and match impedances) as long as they somewhat fall within the RMS range. Mostly confused about the impedance. There isnt anything like a "2-ohm/4-ohm" toggle on any amps, so that leads me to believe that you can use a variety of 2 and 4 ohm speakers as long as they stick to RMS put in place by the manufacterer for each impedance. Ive probably just made this much more confusing. lol

The impedance is all dependent of your speaker voice coils and how you wire it. The amp can run at any impedance you wire your speaker/sub to but you just don't want to drop below the lowest impedance the is rated to drive.

And yes a 5 channel amp is ok to mix different impedances for example you can run the front speakers down to 2 ohms as your saying and then the sub channel is ran down to 4 ohms. As long as this is what the specs of your amp are saying that it is rated for.

Sounds like you have a 5 channel amp already, do you have speakers and a sub/subs yet. If you post the amp make model, speaker and sub make models and voice coil impedances (ohms) then we may be able to help a bit more if everything sounds like it should work and wire in straight in alright.
