Here is a list courtesy of Critr Getr and what he used. Put any type of player whether it be an mp3, dvr, cd player, or just a tape player into the amp/speaker. And walla you have your caller. A word of advice...Go with a Sony Walkman or with one of equal comparison. If you don't you will/might rob yourself of volume like I did.....James L....
Radio Shack #4202420 cable, 6' long with mono miniplugs both ends (use this to connect the tape player to the mini-amp) / $2.69 + tax
Radio Shack #277-1008 Pocket Speaker/Amplifier, $11.99 + tax
Radio Shack #4202434 Miniplug/Stripped / 6' wire, Miniplug one end and one end with stripped wires (use this to plog into the miniamp output) / $2.49 + tax
Radio Shack #4001440 4"x6" Powerhorn, $19.99 usually, on sale for $14.99 + tax
Just solder the stripped wires to the powerhorn wires, or connect using wire nuts. Insert extra wire between the two as desired.
Total cost, $37.16 + tax (You could save money on a cheaper speaker, but I think this one may be worth the difference. I went to 2 NAPA Auto stores, and could not get the CB speaker. I may order one and try it later.)
