Here's the connection using three 3.9Ω resistors in parallel, connected in series with the speaker.Okay. Can you tell me how to connect them and what the real life vs. theoretical advantage is compared to our original plan?
Theoretical Advantage:
Gives an exact 4 ohms to the amplifier, and has a higher power rating of 6W total so the resistors have less stress.
Real Life:
Likely will be little noticeable difference in the sound, the amplifier operation, or the resistor life, between using the three 3.9Ω resistors versus one 1Ω resistor.
