K3503 Low Input VS Line Input

Hello,

For the k3503 amplifier I plan on using 2 subwoofers. What is the difference between using the LINE input and the LOW inputs on the amp? I have the standard RCA patch cord coming from the stereo in the car and would want the low frequencies to power the sub. Higher frequencies(over 100hz) can damage them correct?

LINE is for line level signals, LOW accepts speaker level signals, via transformer.
Best quality is achieved using LINE inputs.
