Combination of 4 ohms and 2 ohms speakers.

Ajaybiz · 14th May 2009, 15:32

Guru's is it ok to install Combination of 4 ohms and 2 ohms spekers connected to one 4 channel amp?
I have JBL components at front and JBL 3 ways at rear, now planning to put Illusions which are 4 ohms in front doors and JBL components at rear doors and removing JBL 3ways, all 4 spekers are driven by GTO 75.4 amp.
Woofer is going to be driven by GTO 301.1 so no issue in that department.
Thanks.

where are the 2 ohms speaker ? or you are trying to say that the jbl compo you have are 2 ohms one

Yes the JBL's are 2ohms.

No absolutely no issues. You will have independent channels driving each set of speakers and each channel is steady at 2 ohms.

You may find that the volume level may differ so adjust according to taste.

Yep sounds like i can control the sound level by gain and fader, thanks all.

But won't this negate the advantage of the 2 ohms speakers ?

?

IMHO, Other than an increased sensitivity, increased current load (only advantageous in case of a small head unit amplifier or a low power amplifier) there are no real advantages to a 2 ohm speaker.

In any case that 2 ohms hype is just a marketing thing. Speaker impedances keep changing depending on the frequency of the sound being amplified through them.

The speaker average a little over 3 ohms, which a little lower than most speakers.

He probably has the GTO series.
