this is all i could find at radioshack
http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=276-1778
but a 13.8 -> 9v would be better, i couldnt find that on their site.
and youre saying it will have wiring instructions? i guess thats what
i was really looking for because im not sure how -- not that i havent
before, ive just never messed with a voltage regulator.
where can i determine the amperage of the speaker? its only about a
2" speaker with a 9v battery attached, i know its way too high for the
alkaline cuz it drowns out after about 10mins.
