if youi can find an oldf computer set of speakers, they are amplfied and put out a nice sound. I have then for a 396xt scanner. While mobile I use iLuv SmashBox 3.5mm Aux Portable Speaker Case (Blue)
by iLuv. Got this off Amazon. Stereo speakers that plug in via 3.5mm plug. Runs off 2 AA batteries, had the same 2 batteries installed sine last dec 2014. Not used every day but when I go mobile, they fill the car with sound, over the road noise . $8.00 for this, $10.00 for the computer speakers that were from an older pc that had been scraped.
