The all new ATOM marine series of amplifiers gives you the best of both worlds! Small footprint and big power!

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!

The ATOM 8W is a class D 8-Channel high power amplifier with 3,500 watts peak output and 880 watts RMS rated power. The power of this amplifier is the real deal! It is enough to power multiple zones all at high volumes that you can hear over engine and wind noise. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the Dyno Certified RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.

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 4 channels has its own set of advanced filters.

As an example; you can use:

  • Channels 1&3-2&4 for 4 full range speakers (in full mode)
  • Channels 5&6-7&8 for subwoofers (in low pass mode)

The ATOM 8W is protected by full IC controlled circuitry with mute, delay, and soft start technology to protect your amplifier and speakers from thumping when you turn your vehicle on.
