[QUOTE="XTRProBoy, post: 2453098, member: 571009"] Nearly all mono amps in the car audio world are designed with the intent of being used to power subwoofers. Most are engineered for high current operation into lower impedances to put maximum power into subwoofer(s). Most are also Class-D and they have limited frequency range* (most top out at about 250Hz)--the purpose of this is because a D class amp is more efficient despite it's limited frequency response. Since only low-frequency response is required for subs, and high power and high efficiency is desireable, those are the amps most people choose to power sub(s). For your application (powering front speakers), as mentioned above, you will not want to be looking at mono amps at all. *There are variations on class D designs that are full-range and used in stereo applications but I won't get into that as those are not that common.
