1200W Rockford Fosgate + Alpine Marine Bass Bundle
Pair of Rockford Fosgate M212S4 12" M2 Series Marine Subs + Alpine PDX-1.600M Monoblock Marine Amp
This Sonic Electronix Exclusive Bass package showcases an Alpine Marine PDX-1.600M Amplifier along with a pair of 12" M2 series Alpine subwoofers. This excellent bass package pushes 600 watts of clean, continuous RMS power. The Rockford Fosgate subwoofers each have a Single 4 ohm voice coil; meant to be wired in parallel, to a final impedance of 2 Ohms. For more information regarding subwoofer wiring, please check out our Subwoofer Wiring Diagram.
These Rockford Fosgate M212S4 M2 series subwoofers require 600 watts of RMS power. The included Alpine Marine PDX-1.600M amplifier will compliment this required power by supplying a perfect match-up of certified RMS continuous power. With the Rockford Fosgate's subwoofers and Alpine amplifier, this bass bundle is great for anyone looking to upgrade their vehicle's audio system

Amplifier Power Specifications
An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.
Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.
Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.
RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.
The RMS output figure is much more accurate than the peak rating when comparing products.
A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.
When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.
The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.
- RMS Power
- Signal-to-Noise Ratio
This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.
If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.
The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.
Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.
Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".
Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.
