you have 2 choices...


Option 1 (parallel) = 2 ohm load

Speakers wired in parallel

Recommended Amplifier: Stable at 2 or 1 ohm mono



Option 2 (series/parallel) = 8 ohm load

Two pair of speakers, each pair wired in series, then wired in parallel

Recommended Amplifier: Stable at 4, 2, or 1 ohm mono




However.... If you split the amp to run 2 on each side, then you can go the other way.


Option 1 (parallel) = 4 ohm load

Speakers wired in parallel

Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

First, I don't think there is such a thing as a 4-ohm amp. The power may be rated at 4-ohms as in


200 watts per channel to 4 ohms, 20-20khz, 0.01% THD, both channels driven


But that simply means the power was rated at 4-ohms, it doesn't make it a 4-ohm amp and it doesn't make 4-ohms Mandatory. Just go with 8 ohms.


If you really want 4-ohms, though personally, I can't imagine why, get Four 4-ohms speakers instead of Four 8 ohms speakers, they are not hard to find.


But to answer your question, which really has already been answered, NO, you can't make four 8-ohms speakers add up to 4 ohms unless you are willing to accept losses.


For what it's worth.
