I just bought a pro 197 and I want to hook up 2 radioshack external speakers to it, they are both identical speakers 8 ohms each, would it hurt to splice the speaker wire together and hook into the external speaker jack and run one speaker beside the scanner and the other one in a different room of the house?

You're gonna turn it into a 4 ohm load. It should be fine but ideally you'd want two 16 ohm speakers in parallel or two 8 ohm speakers in series on two parallel legs (4 speakers in total unless you could find 8 ohm resistors to take the place of a speaker on each end).

Doesn't the Pro 197 have two speaker jacks? One in the front and one in the back? I don't know if that will work for you or not since I've never tried to plug an external speaker into my Pro 197.

From a quick glance at the manual, the front headphone jack will interrupt the on-board speaker. I'm not sure about whether the rear jack does also or not.

The manual specifically states that external speaker should be connected to the rear jack, not the front.

Hope this helps,

Yes pluggin in an external speaker in the rear does stop the onboard speaker from working.

W5PKY gave you solid advice. Have a look here if you dont know what he is talking about:
Wiring Diagrams | Eminence Speaker
That is a page for subwoofers but the same still holds true.

More resistance = less power being pulled through the sound circuit in the scanner and probably a lower volume at each speaker compared to having just one.
Less resistance = more power being pulled through the sound circuit in the scanner and possibly burning up something. It may be able to handle a 4ohm load or it may not.

If you dont know how to add up the ohms by looking at the diagram, then all you have to do is wire it up or use the splitter and check the mono tip going into the scanner with a multimeter. That will tell you exactly what you have. Chances are it wont be exactly 8.00 ohms, 4.00 ohms or 16.00 ohms but it will be a fraction off. That is normal.

My advice is to go get a pair of amplified computer speakers from Kmart or Walmart, a mono to stereo adapter, and some extra wire. Plug the speaker plug into the adapter and the adapter into the scanner. Splice X amount of feet of wire between the two speakers so now you have one speaker (the one with the power button and ac adapter) where your scanner is and the other will reach to your other room. I use computer speakers on all of my scanners in the house and I never have to worry about not being able to hear it.

If I wired the 2 speakers I have up in series, making 16 ohms would that be ok ?
Yes but like I said above you are going to loose some volume. It may be loud enough to suit you. There is not alot of power coming out of the external jack to begin with. Personally I dont believe I would do it like that.

Read series and parallel towards the bottom of the page.
