how to hook up 2 pairs of speakers to 2-channel amp
Hello all,
I have 2 pairs of speakers:
1. Cerwin Vega VS-150: 4 ohm speakers
2. Cerwin Vega CLS-215: 8 ohm speakers
I am interested in the Cerwin Vega amp: CV-900. This is a 2 channel amp with rated output:
8 ohm - 210 W
4 ohm - 320 W
2 ohm - 420 W
I emailed Cerwin Vega's tech support asking them how to hook up my 2 pairs of speakers to a single amp. I've gotten these responses so far:
1. two speakers of same impedance may be connected to a single output (i.e. in parallel?)
However speakers of different impedance may not be connected together
2. they can be connected using speakon connectors (not sure what that means)
Next my friend, Peter, said they can be connected either in parallel or serial:
1. parallel: the new impedance will be: (4*8)/(4+8)=32/12=2.6
Peter says they advertise they can handle 2 ohm.
Is that ture?
2. serial: the new impedance will be: 8+4=12
Peter says this is also okay as long as it is greater than their advertised 8 ohms.
Is that true?
Thank you,
Omid
