First off I will say this amplifier is efficient and very reliable. It will handle low voltage dips into the low 11's and not even hit protection mode. I have had this happen when I had a failing alternator. I will also say it does its rated rms determined by a clamp meter @ 13.8 volts It put out right at 2530. It is a solid built amplifier,the only cons I can see so far are the lack of adjustable subsonic cutoff and the length of the amp. It is a pretty large amplifier for 2500 watts but is well worth it. It will handle a 1.4 ohm load daily with NO problem with a proper charging system. If its 2 ohm power you need and you have room for this amp this is a great choice at a great price.
