Went on ahead and took pics:
The Amplifer is Radio Shack model277-1008C, runs on 9V battery and easy set up. Just run head phone jumper (normal headphone jack)from external speaker output on Scorpion to the input on Amp and then another jumper to from the external speaker output on amp to biga$$ horn speaker. you can adjust the amp volume because it is alos a speaker but once you plug in the jumpers it cancelles out the speaker. this allows you to adjust the amplified output to the horn making it 3 times as loud and the internal speaker on the scorpion. i drilled a hole in the box to run antenna out of and it work great...like i said lil bulky but about $20 in parts cuz i had the box and thats $90 cheaper than the speakers that FoxPro offers on their website.
BTW drrxnupe...did not mean to hijack...sorry
