Yeah the Kicker has a fixed SSF and it has bass boost and a remote bass knob, I turned off the bass boost and compared them both and there is really no difference in the two but I do like the Remote bass knob that is on the Kicker but the MMATS does fit in my truck better, it is alot smaller than the Kicker. The MMATS only has a Frequency adjustment and a gain adjustment. I am going to leave the MMATS in my truck becuase I do have limited space. I have a 1992 Toyota extra cab 4x4 with a 12" IA DP in a 2.5 cu box tuned to 34Hz with this amp, I guess I really didnt need to upgrade. Both amps push this sub hard, louder than you can really stand in that small area.
