When your car is off, is your amp still on? Sounds like a drain somewhere, yet your comment:
The only time I happen to need a jump is when I physically press the "off" button and then remove the keys.
Is very interesting, what happens to the cap when the car does not start? Does it still read 12V? Corrosion can be a HUGE part of the problem, it will show good voltage, but very little current will pass. SO you may hve 14V but very little amperage. this also would explain on bass note voltage dropping from 14.4 to 12.8 instantly. You do not have enough current to keep with the demand.
This is why audio cable is made with Oxygen Free Copper, the guys using "welding" cable will one day have a problem like you describe and wonder why.....
