Question about speakers impedance

[radovantz]

Hi..

I need an advise about speaker impedance..

Can I use an 8 ohm speaker terminal to drive 2 unit of 4 ohm speakers?
Am I right to say 2 unit x 4 ohms = 8 ohm?

Nope. The lower the impedance, the harder the speakers are to drive.

Two 4ohm speakers used in parallel will mean the amp 'sees' an impedance of 2ohms, which would be enough to trigger most protection systems.

Thank you Mr Andrew.. luckily I have not done it before seeking advise. thanks
