2 Great questions. with the current setup ( excluding the amp ) yes it will be able to be powered by batteries. Due to the voltage needed for the other amp I will need to do more tests to see how the amplifier preforms at 15v, which is within its operating range. Obviously it will not be able to supply its full wattage on 15v.
My goal would be to use the existing tuner. But that being said I'm looking at digital tuners that i can fit inside as an option. I would get acrylic cut to black out extra space. Not best case scenario on this unit - I want to keep it the way it looks.
I'm watching your magnavox project closely, I also have one these boxes and would love to update it but i can't decide on a direction.
Cool man, well, if your able to find the radio signal on the board, reroute it to the new amp and use the stock switch to go from Bluetooth to FM to cassette (or what ever you plan to use) that would be awesome. For me, that's kind of the Holy grail that I have been trying to do. Reroute around the stock amp.
Thanks for having a look at the Magnivox thread. I have a very long road in front of me
