ACX-300.1 vs ACM 1.300… what’s the difference?

General

For a basic car audio setup, is the only difference the inclusion of the bass remote port? The ACX is much cheaper than the ACM, so I was thinking of just going with that if they work the same.

A bass knob is pretty important since not all songs have the same bass level.

I was wrong about that. Looks like both have support for a bass knob actually.

I have the ACM 300 and it works great powering an 8-inch Infinity Kappa.
