• PA microphone
• Birth sheet with tested power
• Mounting screws
• Warranty card
• Owner’s Manual

Description:

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.
We went a little overboard (no pun intended) to make this amp marine ready. We conformal coated the PCB board with a waterproof glue that is painted on to protect the circuitry. We then added waterproof silicone covers over the terminals so that water can never get into the amp. The heat sink, including the bottom plate, is made of aluminum which is rustproof. The end panels, internal mounting screws and hardware of the amp are made of stainless steel and are rustproof. Even after many years of use the amp will be rust free and operate like new!

The DBM45 is a 4-Channel high power amplifier with 2,000 watts peak output and 500 watts Dyno Certified power. Here at Rockville we offer the best value in car audio. We therefore want to make it easy for you to compare our products to any brands on the market. 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 our crossover supports low pass, high pass, bandpass, and subsonic. 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 the high pass and low pass mode. 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. Lets 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.

The dBM45 is protected by a fully IC controlled circuit which includes mute, delay, soft start technology so that the amplifier will turn on safely every time and protect your speakers from popping.

We are so confident in your satisfaction with this amplifier that we will offer you a 90 day money back guarantee. If this amp does not perform as well as you expected, we will send you a pre-paid shipping label and give you your money back. This means that, if for any reason you want to return the amplifier for a full refund within 90 days, you can! (Amp must be complete along with the box).
