Do PA D####.# car amplifiers have balanced inputs?

Do the PA D1000.1, 2000.2, 4000.4, and 5000.5 car amplifiers have balanced inputs?

I'm currently planning an install in a car whose head unit outputs balanced signals. I want to ensure compatibility without having to install a line out converter (LOC) in between the head and the amp to convert the signal from balanced to unbalanced. I'd prefer to connect directly from the head unit to the amplifier without any additional electronics.
