Ryn-oh,
I built mine with a Amp and 25w speaker that I bought at a Electrical parts store. If I remember right it cost me about $125. total and that included all the bells and whistles, I could think of 12v, battery, water proof hard case, volume control, blinking power on/off light, 2 chargers one for home and one for auto, you can run a light off it also if need be, extra speaker jack, I run it with two 25w horn speakers now but the weight is around 7lbs with one speaker.
It was fun to build and I got a lesson in how to solder along with a few others LOL. I use a Sony MiniDisk for a source that was the biggest cost of the whole project.
Don't ask me for the technical data as I don't have any of the spec sheets any more. Rob In AZ was a big help in giving me some good advise before I ran into trouble you might search back a few months in elect calls for our posts.
The cheapest way I found was to buy a Radio shack power horn pa system (on sale $80), take the mike apart and cut the wires to the microphone and install a 1/8 female plug $1.25, fits nice in the top. Pull out the case for the 8 D-cell batteries cut the wires and crimp on a pair of battery clips .50, you might have to add a small pice of wire, install a small 12v battery $9. plug in your tape player or what ever and a way you go! It's a LOUD SOB, if you ever need to call in hurricane winds, Plus a siren for locating. (The siren eats the battery). if you run it hard wired you can wind the wire around the horn speaker, 200' easy. I built one and it sits on my shelf incase I ever need it
Jake in NC,
What your looking at is a Dennis Kirk.
That's what i had to start with and ended up rebuilding, better speaker and a rechargable battery in a better case (plastic ammo can) then I just built a new one from scratch, that I think works better. I must admit the Anchor product never gave me trouble till I took it swimming, must have been something in the name?
