How To Install a Marine Amplifier onto Your Boat: Atom P20 Product Video: Description: The all new ATOM marine series of amplifiers gives you the best of both worlds! Small footprint and big power! These amps also have great features like built in Bluetooth wireless audio playback and a built in volt meter. The ATOM P20 is a class A/B 4-Channel high power amplifier with 1,600 watts peak output and 440 watts true RMS power. The RMS power is tested on a dyno using the certified run. It puts out 110 watts x 4 channels at less than 1% THD at 14.4 volts. We give the true power and the peak rating so you can easily compare this amp to any brand on the market regardless how they like to rate their products. This amp has enough juice to power either (8) speakers, (4) speakers, (2) subwoofers or a combination of subwoofers and speakers. It is also perfect for mids and tweeters. This amp has a very cool fully adjustable 12dB/Octave crossover. What is cool about it is that the crossover supports low pass, full, and high pass. This makes our amp ideal for subwoofers (sealed and vented), full range speakers, midrange speakers, and even tweeters. In high pass mode we allow you to filter out the lower frequencies (cut-off frequency adjustable between 50Hz - 250 Hz). In low pass mode we allow you to filter out the upper frequencies (cut-off frequency adjustable between 50Hz - 250 Hz). In full mode you will not be filtering any frequencies. Our advanced crossover technology will allow you to really fine tune each speaker to get the sound you desire. The other cool thing is that this amp has 2 of these crossovers. Every 2 channels has its own set of advanced filters. So if you wanted you can use 2 channels for subwoofer(s) and the other 2 channels for full range speakers This amp utilizes high grade marine components including a conformal coated PCB board with a waterproof glue that is painted on to protect the circuitry. The heat sink casing including the bottom plate is made of stainless steel which is rustproof. The end panels, the internal mounting screws and hardware of the amp are made of stainless steel and are rustproof as well. Even after many years of use the amp will be rust free and operate like new!
