With the voltage at the amplifier staying at 14.3v, I don’t see how the alternator is the problem. That amplifier should drop below 11v before the protection circuit it cuts off.
If you want to check it, have a buddy give you a jump start. Have both cars running and connect a set of jumper cables. That way you have 2 batteries and 2 alternators powering the amplifier. If the amplifier still cuts off, the alternator is not the problem.
