Any suggestions guys?  Any other solution for this besides buying another amp or switching speaker cables?

You will need transformers for your amp and individual speakers. this is the set up for pipe in systems using multiple speakers.

OR, if your amp can drive 8 ohms, try cabling the speaker using parallel/ series connection. if your speakers are 8 ohms, the computation for one channel with 3 speakers is series = 8+8+8= 24ohms; parallel = 24ohms /3speakers = 8ohms average impedance.

Has anybody tried this?

isnt it 2.3ohms average? (8ohms/3)

You need a speaker selector. I have seen some in ACE (costs around P3K), or make your own

Hope this helps

yes, it will be 2.3 ohms if purely parallel. if series / parallel = 8 ohms. try it. An amp will have difficulty driving at 2 ohms even if it is rated with that impedance level.

if purely parallel = 2.3 ohms; if series / parallel = 8 ohms.

yes, this is correct, if you can get a 24ohm to 8 ohm matching transformer, then you are in business..... ;D
