Mustang Starting Problems

I've been having some issues with my electrical system lately in my
car. My stereo decides to turn off at will. If i disconnect and
reconnect my battery, the radio works fine for a bit, then shuts off
eventually. This last time though, I decided to disconnect my negative
wire too. Big mistake I guess... After reconnecting the battery, I
attempted to start my car. Made a click sound then everything
electronic shuts off. Back off the ignition, and my clock would fade
back and my capacitor would give me a reading of like 6.5 and slowly
climb back into the 9 range. I backed out my dad's car and attached
some jumper cables, and after a little waiting the engine turned over
just enough to start, but nothing electronic really worked(I didn't
check my headlights which i regret not doing now). I waited till this
morning, and tried to start it again, this time with a portable
battery jumper. The engine made a constant clicking sound, but
everything else stayed on(ish). Any ideas on what the problem could
be? I took my battery to the local auto parts store and the battery is
in good shape, and I have it on the charger as i type this. I'm going
to pop it in and see if that helps, and if it starts I'll go get my
alternator tested. I've also thought that maybe its my solenoid? Any
and all advice is greatly appreciated.

Thanks in Advance,
Rick

Sounds like a bad connection. Could either be ground or Positive
connection. You will need a Voltmeter to check for voltage drops.
