The all new dB marine series of amplifiers gives you the best of both worlds! We took the sound of our best-selling series of dB car amps and we added top of the line marine grade parts so that they will last forever and withstand even the harshest conditions on the water. 

Now we went to extreme lengths to make this amp TRULY marine ready. We conformal coated the PCB board with a waterproof glue that is painted on to protect the circuitry. The Heat Sink, including the bottom plate, is made of aluminum which is rustproof. The end panels, all of the internal mounting screws and hardware of the amp are made of stainless steel and are rust proof as well. 

We then added waterproof silicone covers over the terminals so that water can never get into the amp. 

This amp has a fully adjustable 12db per octave crossover with differential circuitry. What is cool about it is that our crossover supports low pass, high pass, bandpass, and subsonic. And you have individual crossovers for channel 1 & 2 and channels 3 & 4. This makes our amp ideal for subwoofers (sealed and vented), full range speakers, and midrange speakers. 

In high pass mode we allow you to filter out frequencies between 15Hz - 4K Hz. In full mode you will not be filtering any frequencies. The really cool part is in low pass mode you can use both the high pass and low pass filters. So for example you can set the low pass mode to 50 hz, and then you can set the high pass to 15 Hz. In this case you would be playing frequencies in the range of 15-50 Hz on this channel. This would be an example of using the subsonic filter. Another option you have is for midrange speakers, you can use our low pass filter and set it really high. Let's say to 150 hz. And then you can set the high pass to 3K hz and your midrange speakers will only play that frequency range. Our advanced crossover technology will allow you to really fine tune each speaker to get the sound you desire. And give you a lot of flexibility in your setup. 

You could run all full range of speakers off of this or bridge two channels together run a marine subwoofer of that and then run full range speakers off the other channels - You have a lot of options! 

For my setup I took 8 Full Range Speakers and set all the crossovers to FULL mode. Want to hear how loud it is? Check out the video below:
