I just picked up one today at a garage sale. Can I use a 10 ohm speaker to test this with or is this too low?

I think 10 ohm OK for test. As always watch your connections a loose one can blow the output diodes.

Thank you.

I think that this will be part of the Halloween decorations this year. Between the skeleton on the tricycle having it's shirt being pulled by a skeleton dog, some lighting and now the sound effects.

Or as a bonus, if anyone with an outstanding warrant is outside they might break and run.......

IF you plan to use only the PA mode and keep the volume low, you'll be fine with a low wattage speaker.

On the other hand the siren mode will destroy any speaker not capable of the full wattage the unit puts out.

Those units will blow up a 12 volt headlight bulb being used as a dummy load.

watts and Ohms are two different measments. watts is power the other ohms is resistance. If the resistance of the speaker is off you can damage the siren. if the watts the siren puts out is greater then the speaker can handle you damage the speaker. The older ones put out 25 watts and if memory serves me right they require a 11 ohm speaker. But I get numbers tangled so best to check that.

Blow up, as in shattering or exploding the bulb itself, or only blowing out the filament.
