I too was fed up with not being able to make out what the voice was saying... The speaker built into the LI is good enough for the siren, but the voice alerts sound like a 1980's McDonalds Drivethru!
So I went and picked up an external CB speaker.
SPB2 Compact Big Mouth Extension Speaker - Durham Radio Sales and Service Canada
It's not powered, but it's more than you'll ever need to hear it clearly. If you *really* want the cars around you to hear it too, just get a bigger speaker.. paying double for a powered unit is insanely overkill and completely unneccesary.
BTW - an 8Ohm 2 - 5 watt speaker is what you should be looking for.
