2ohm V 4ohm speakers

ok if my RECIEVER is rated @ 22 rms per channel and 50 watts peak X 4

is that rated @ 4 ohms?

if i hook up 2 ohm speakers like infinitys what would the power be?

Yes (depending on the deck, I doubt you'd actually get a full 22w out of it at 4ohms). .

In reality, probably not much more than that rated 22w

Headunit's internal amplifiers weren't designed to provide large amounts of power, especially into low impedance loads.

Double check also. Your headunit's amp may not even be stable into a 2ohm load per channel.

Poof, there goes that magic smoke.

I've never seen a HU that said it was stable into 2 ohm.

The older Pioneers were.

Hell, in the manual it had a diagram showing you how to bridge the rear two channels to a 4ohm subwoofer, providing a whooping 70w RMS of power.

i would need a 4ohm stable amp correct? to hook up the 2 ohm speakers then right?

no, you would need an amp that could push a two ohm load

i wouldn't do it. as undercover said "poof" is correct. But what do i know, i see people with 12 some odd tweeters hanging from their headliner.

they may also be idiots... or the ohm loads on the tweeters may be higher, allowing you to bridge them in a way that it makes a 4 ohm load.. or they could know basic math and how to put the speakers in series of parallel loads so that it all comes out to 4 ohms... math on resistance is weird... but if you do it right, you get mad props from audiophiles around you... considering you successfully hooked up 28 speakers in your car off of a single 4 channel head unit... lol theres a calculator online that shows how to put speakers in parallel and in series and you put in the ohm loads and it spits a number at you... search google for it... hell i even did it for you... go here http://caraudio.biggz.com/downloads/ohmcalculator.html and download that program... youll be happy... youre welcome

Yes - because people that consider themselves true audiophiles will be greatly impressed by an install that (a) Is incredibly impractical and (b) sounds like hammered crap (as driving 28 speakers off of a headunit inevitably will regardless of whether or not you got the impendence shown to the deck's internal amp right or not)

so that 22 rms rating is rated @ 4 ohms

the deck most likely cant power 2ohm speakers

a 2ohm stable amp would power the infinity kappas (would it sound good)

thats my summary am i right or wrong?

if i have 4 speakers powered by a 4 channel amp and the speakers are 4 ohms will they still recieve power from the head unit or is it just the amp now?
