Home Speaker Asylum

General speaker questions for audio and home theater.

Re: Ohms?

Yes,you could use just one 4 ohm resistor,but it only has a 10 watt power rating...

Since average power levels are generally considerably lower than peak,it may be all you need.If you play something loud with lots of bass,however,you may need a bit more.

Using five 20 ohm resistors in parallel will give you 4 ohms,with a 50 watt rating.Or you could use four 16 ohm resistors for a 40 watt rating.Or two 8 ohm resistors for a 20 watt rating.

I wouldn't rely on the thermal overloads on the amp to protect it.Better safe than sorry...At 98 cents per resistor,it's cheap insurance.
