Which Power Amplifier is Right For You?

The amplifier is something that is essential to all PA systems. Knowing what you need based on the speakers you have is very important. There are several different things to look for in your amplifier, but first determine the resistance (or Ohms) of your speaker cabinets.  Remember that daisy-chaining speakers will change the overall resistance.  Next check out the power rating of your speakers.  You’ll be looking for an amplifier that produces 1.5 times the RMS rating of your speaker at the same resistance as your speaker.  Listed below will be some of Seismic Audio’s best amplifiers for your needs.
