Amplifier wiring

[jack206]

First off, hey all just joined.//content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif

Hope i've posted in the correct section here.

Right I have just bought a 4 channel amplifier with the specs of

4x50rms at 4ohm

4x75rms at 2ohm

1x150rms bridged at 4ohm x2

It also states the amplifier is 2ohm stable

I have 4 Coaxial speakers that I want to get the best out of, they are all 4ohm speakers.

I am wanting to run the speakers at 75rms each so how do i do this?

Also am i right in thinking if i connect the speakers in a standard way to the amplifier i would have a 4x50rms output?

you can't because each speaker is 4 ohm

and you would need 4- 2 ohm speakers to ohm the amp down to get

your 75 watts per channel.

you'd need it to be stable bridged @ 2 ohms x 2

And even if you did run it at 2ohms your SQ would suffer - no headroom. So while it may hurt to not get that extra output it's actually for the best.
