"Rock That Small Space"

The Rockford Fosgate P3S 12" shallow mount subwoofer delivers Punch, even in depth limited situations. Rockford Fosgate understands all vehicles are not the same, because some cannot accommodate deep subwoofers. In the past, that meant no Bass. Not anymore! Now even depth challenged vehicles can have REAL Bass and the Dual Voice Coil allow configurations for every application.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Punch P3 Shallow Mount (Rockford Fosgate)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Peak Power Handling
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. The Peak power handling specification is typically rated per speaker unless otherwise noted.
800 watts
RMS Power Handling
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 powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
400 watts
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
4 ohms
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
43 - 250 Hz
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
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".
85 dB
Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.
8.4 mm
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Round / Circle
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Woofer Composition
Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.
Anodized Aluminum
Woofer Surround
A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.
Santoprene Rubber
Magnet Structure
Defines the overall structure of the subwoofers magnet.
Single Stacked
Subwoofer Grille
Most subwoofers are able to accommodate a universal grille; however, some subs include a grille and others have a specific, optional grille available for purchase separately. If "yes", then the subwoofer includes a grille. If "optional (sold separately)" the matching grille will need to be purchased in addition to the sub.
Re-Cone Kit Available
Some higher end subwoofers have replaceable cone assemblies. In case of a blown woofer, a recone kit allows for a simple replacement, as opposed to purchasing an entire new subwoofer.

Recommended Enclosure Specifications

Optimum Sealed Box Volume
This value indicates the ideal sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Optimum Ported Box Volume
This value indicates the ideal ported box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Top-Mount Depth
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Cutout Diameter
The actual diameter of the hole you will need to cut out if you are creating a new mounting location for this speaker, or if you are mounting a subwoofer in a box.
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.


Electromechanical Parameters

Equivalent Compliance (Vas)
This is the amount of air that has the same stiffness as the subwoofers suspension. The greater the rating, the lower the stiffness and larger recommended enclosure. It is measured in Liters.
35.3 liters
Total Speaker Q Value (Qts)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including all dimensionless losses. Essentially, a high Qts value (closer to 1.0) means the subwoofer is great for sealed enclosures and a low Qts value (closer to 0) means the woofer is great in vented enclosures. A Qts of around 0.45 means the woofer will work decently in either enclosure type.
Efficiency Bandwidth Product (EBP)
This number represents the trade off between having an efficient woofer and one with a wide bandwidth. To calculate this number, take the Fs and divide it by the Qes. If the number is below 50, the woofer is designed for a sealed enclosure only. If it's between 50-100 it can be used in either. Lastly, if it's greater than 100 it's designed for vented enclosures.

More than I expected.

August 31, 2014

First of all I have a 2001 ford f150 single cab so I can't fit more full sized subs behind my set so I was looking at a lot of shallow mount ones. I'm running on 12 rockford and a true 1000 watt planet audio amp and I can say it completely shakes my whole truck.

Pros and cons
Amazing price
Great bang for your buck
Super fast shipping
And it's a rockford fosgate
Sounds amazing for a shallow mount
Its a shallow mount but if you don't have the room it's perfect.

I would recommend this product to anyone it's just a steal.

They're amazing.

March 17, 2015

Everything I run in my truck is fosgate and these just added to the amazing sound of fosgate. The only con I see in these is that anything more than 1.5 cubic foot they won't sound good. Pros? Loud, sound amazing, very clear sounding deep and rich bass. I have 2 shallow 12's and 1 15 and everything is wired down to 2.67 ohms on a 4500w mono class d power acoustik and they go all day long. They get warm but never hot enough to shut off. I'd recommend these products to anyone. They're cheap and powerful. I can be heard from a little ways away. You won't hear these things from miles away but people will know when your coming.

I just put them in yesterday. 2 of them in a 1.8 cu ft shallow sealed box as a false floor in a 2009 Jeep Grand cherokee. Lets just say the suspension on the subs is STIFF! Im sure they will take some breaking in to get them to their optimum performance to loosen up. That said, first impression, they are loud and tight. They hit low but at high power they distort a bit at the low end. Might be that i need to adjust the gain on the amp (A cerwin vega stroker 1000.1) but the bass is all the way down on the HU. so far i like em. My wife says they sound better than the single Alpine Type R 12 in ported box. She said the alpine was "too rumbly" and these sound more clean.

However, the Type R 12 in ported box was just as loud, and was running at half the power and never bottom out... time will tell and I will update my review later.

great subwoofer

March 6, 2015

Considering the price these are the best shallow mount subs. There better than some high end subs I've owned that weren't shallow mount. I have 2 in two separate sealed enclosures and the output is amazing. I'm going to build one ported enclosure eventually but this is more than enough for now. Anywhere space is an issue these are the subs to buy

Great Subs

March 28, 2015

Bought these subs for my Silverado. Paired with a Sony Xplod amp. These subs hit hard. And for the price they are that much better, I would totally recommend.

best sub for the price that would fit in the small depth box purchased
Brandon L on Dec 18, 2014
P3 Sound in a shallow mount dual 4ohms!
Joshua T on Nov 17, 2014
Having a regular cab pick-up where space is really tight behind the seat I chose the RF-P3SD4-12. Shallow fit, DVC for safe 2 Ohm load, RF Quality, and Sonic Electronix great pricing and service. Can't beat it!

hits very hard and reliable, bang for the buck
Omar C on Oct 23, 2014
can you wire this speaker to 2 ohms?
will it be okay if i wire it to 1 ohm on a hifonics brutus X14 1100.1D?
alejandro t on Feb 19, 2015
Best Answer: It's a dual voice coil subwoofer (4 ohms per voice coil), so wiring it in parallel will give you a 2 ohm load. Running only 1 of these to that amp will give you a 2ohm load and a max of 700w RMS. I wouldn't recommend it. In order to get a 1 ohm load, you'd have to add a second subwoofer, also wired in parallel. With that amp and two subwoofers, this setup will give you around 550w RMS max to each sub. You should be fine with that setup as long as you watch the gain.

It's a solid sub, and even though it's shallow, it's sounds amazing. Good luck!

Best Answer: Yes for sure! The Epicenter will add more "umph" and bottom end with the P3SD4 especially if you listen to hip hop or latin music.
