I was finally able to get this into a non protoype form. I change the code a little to make it more usable. Contruction techniques for the final version was a mix of wire wrapping and some small guage wire soldering. I replaced the relay module I use in my proto type with a much smaller unit to fit in the speaker enclosure.

I found a Kenwood speaker in stock pile and it was large enough to house all the electonics..

When the case is open there is a lot of room around the outside edge. I tried several other speakers but just couldnt find the room and didnt want to use an external box for the electronics.
