This amplifier's filters can also be configured as a true 3-way crossover, with a low-pass filter for the subwoofer channel, a bandpass filter on Ch. All three filters offer continuously variable cutoff frequency selection from 50-500 Hz.
MARINE 5 CHANNEL AMP PLUS
The M700/5 includes a 12 dB / octave high-pass filter for one main channel pair, a 12 dB octave high-pass or bandpass filter for the other main channel pair, plus a variable slope low-pass filter for its subwoofer channel. The breakthrough that makes this much power possible in such a small chassis is our NexD™ switching design. With this incredible little amplifier, you can drive two pairs of quality component speaker systems with plenty of clean power (75 W x 4 4 O), while also delivering a stout 300 W of power to a subwoofer system.
Marine amplifier dyno sites like Willitson Audio labs dyno'd the amplifier at 150 watts per channel at 4 ohms for the speakers and up to 821 watts to the subwoofer.The M700/5 is ideal for a complete audiophile-grade, subwoofer + four satellite system, and it fits comfortably in just about any boat's weather-tight compartments. Now let's take into consideration that it uses an unregulated power supply and we know it is putting out more power than it's actual rating. If we measuredthe output of the TM1000x5ad like most other amplifiers, even other Rockford Fosgate 5 channel marine amps, this would be a 1400 watt amp. If we are conservative, that is an additional 600 watts RMS, taking the subwoofer power at face value. The subwoofer channel puts out 600 watts at both 2 and 1 ohm. This is the equivalent to 200 watts at 2 ohms on most amplifiers, making this an 800 watt amplifier for the speakers. You get 100+ watts of raw, Rockford power to each speaker at all impedances at rated power.
MARINE 5 CHANNEL AMP FULL
This amplifier has constant power circuits for both the full range and the subwoofer channels. In my not so humble opinion, the best 5 channel marine amplifier is the Rockford Fosgate TM1000x5ad. What is the best 5 channel marine amplifier? If your marine radio has 2 channel pre-outs and a subwoofer, you will want to set it to 5 channel inputs, but then use "Y" RCA cablesto send the audio signal to both the front and rear inputs. It takes the audio signal from the 4 speakers, sums it, filters out the high frequency signal that the subwoofer can't play, and sends that to the subwoofer. If you have 4 channel pre-outs but no subwoofer pre-out, the same thing is true. This allows you to run a 5 channel marine amplifier on your boat, even if you only have 2 channel zone pre-outs. It then takes the sub-bass frequencies from the speakers, sums it, and sends just the bass frequencies to the subwoofer channel. If you set the selectable input switch at 2, the amplifier takes the left and right input signal and sends it to all 4 speakers. This let's you select whether you have 2 channel, 4 channel, or 5 channel inputs going into the 5 channel marine amp. All of the 5 channel marine amplifiers that we offer have switchable inputs. Can I Use a 5 Channel Amplifier with a Marine Radio without a Subwoofer Pre-Out?
