Speaker Amp question about ohms

Hello,

I have a Pioneer GM-6400F amplifier that runs at
60 watts RMS x 4 at 4 ohms (75 watts RMS x 4 at 2 ohms).

If I get front JBL GTO638 and rear JBL GTO938 will my amplifier automatically run at 2ohm per channel? These speakers have 2 ohm impedance.


I read that...
"Impedance is a characteristic of the speakers, not the amp. The only way to make your amp run at 2 ohms is to connect it to 2-ohm speakers (or combine speakers so that the load at the amplifier is 2 ohms)."


So again... If I connect all four speakers to each separate channel, each channel should be running at 2 ohms right?

Thanks in advance

To answer your question, yes. As long as the speakers you are installing are 2 ohm speakers, then connecting each to it's own channel on the amp will achieve the 2-ohm power rating from the amp.

Well we need specialists in every aspect of the car haha. Hopefully next year sometime I can start to think about a stereo install for the Saturn Vue, call me crazy, but I think:
1) A stereo system in an open air space vehicle is just much better.
2) Cobalt is going to be race car ish, obviously nothing to ridiculously fast, but why waste weight in the cobalt when you have an SUV lol, maybe just a single kick ass 10" for the cobalt.

Sorry for the thread jack OP lol.

open air space vehicle? like a hatchback vs a trunk car? because if that's what you mean thats not really an opinion but more of a fact. Its acoustically better in every way imaginable.
