2 Ohm or not 2 Ohm that's the question

Hi,

I am just in the progress of installing a Bose rear unit in my car (see http://www.renntech.org/forums/index.php?showtopic=11577) I should be finished this wekend and will then update the thread.
Might be interesting for you as the speakers in the Bose box are 3 and 1 Ohm not 2 Ohm

to be continued ...

Hi,

If you are wiring the 3 Ω and 1 Ω Speakers in parallel, your total impedance is 2 Ω - see: http://www.986forum.com/forums/showthread.php?t=9180 Hope this helps...

Happy Motoring!... Jim'99

laws of physics

Jim, thanks for the tip,

but the formula for putting resistors (speakers) in parallel is:

1/RTotal = 1/R1 +1/R2
==> 1/RTotal = 1/3 + 1/1
==> RTotal = 1 / (1 + 0.33) = 0.75 Ohm

No, I am not a teacher just an electrical engineer (no kidding)

Cheers
