i was wondering if there was anyway possible to take a car stereo
system and inbed it into lets say a wall and hook it up to speakers
and everything but run it off of the electrical outlet in the house?
what would i need to rig up so that i could avoid the whole car
battery set up which would need a constant charging that would build
up hydrogen gas and pose as a potential fire hazzard? if any of that
made sense, i appreciate your help.
If you are doing this to get stations you can't get on your AC radios,
I"m told it won't work. I'm told car radios get such good reception
because of the car itself, maybe because it forms a ground plane
around the base of the antenna.
If that is true, how well do the radios in Saturns work? They have
all plastic bodies.
A 13.8v base station power supply such as you would use for powering a
mobile CB radio indoors, is all that's needed. You can also safely use a 12v
battery, by using a sealed gel-type, such as is found as the backup supply
in alarm panels and emergency lighting. I'm not sure that the groundplane
argument holds up. On vehicles where the antenna is wing mounted, the
groundplane is very lop-sided. Also, vehicle antennas tend to be
electrically short for the frequencies concerned, and don't contain anything
in the way of loading coils to address this, so end up being pretty
inefficient things.
