All your bass in one place

Bulletproof bass

Rockford Fosgate designed the P2D2-12 12" subwoofer to handle up to 400 watts RMS, dishing out the kind of powerful low end you crave in your ride. Its responsive paper cone is reinforced with the same Kevlar® fibers used in bulletproof vests so you get the best of both worlds — warm bass that's exceptionally hard-hitting. Rockford Fosgate uses a new technique to attach the oversized rubber surround to the cone that increases available cone area up to 25%, so this sub can push more air for even bigger bass. Dual 2-ohm voice coils allow you to wire these subs together for the correct 1-ohm load for the Prime amplifier.

Prime amplification

Rockford Fosgate's versatile R1200-1D mono amp puts out 1,200 watts RMS to the two subs in this package (extra power is a good thing). Rockford Fosgate designed this Prime amp to deliver Power Output Without Excessive Regulation (POWER), which means it'll respond quickly to the peak demands that you may throw at your system. Low-pass and subsonic filters, along with Rockford Fosgate's famous Punch bass boost, let you tune your subs for maximum performance, so your driver's seat will become your favorite place to pick up the beat. And, speaking of the driver's seat, you can hook up the included wired remote knob to get fingertip control over this amp's bass impact.

Box of boom

Sound Ordnance's rugged BB122-125S sealed enclosure holds two 12" subwoofers and offers an internal volume of 1.26 cubic feet per chamber. This unloaded box features high-grade, medium-density fiberboard construction, with sealed inner braces that help combat resonance by reducing vibrations. Rounded outside corners and recessed panels allow it to fit into more vehicles, while tough black carpeting defends against incoming nicks and scratches.

Amplifier
Subwoofer
Enclosure

Amplifier

Overview: The Rockford Fosgate Prime R1200-1D is a mono Class D amplifier. It is optimized to power subwoofers, and is 1-ohm stable. The Class D design is very efficient with a cast aluminum heatsink to keep it in a small footprint. The amplifier has 85% average efficiency at 4-ohms or 2-ohms, and 80% at 1-ohm.

CEA 2006 Compliant: The R1200-1D's power ratings are measured according to the uniform standards advocated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output and signal to noise ratio of all CEA-2006 compliant amplifiers, even different brands. Manufacturers who adhere to these standards can display the CEA-2006 logo on their products and packaging. The RMS power output is as follows (measured with a 14.4 volt input, <1% THD+N, 20-250 Hz):

4-Ohm: 400 watts x 1
2-Ohm: 800 watts x 1
1-Ohm: 1200 watts x 1

LED Indicator: The amplifier is equipped with a top-mounted LED indicator which illuminates blue when the unit is turned on. The LED illuminates red when a protection circuit engages (short circuit or too low an impedance is detected at the speaker connections). The amplifier automatically turns off if this occurs.

Mounting: The amplifier can be mounted vertically, horizontally, or inverted using the supplied mounting screws; horizontal mounting (right side up) will provide the best cooling.

Controls:

Gain Control: Use the amplifier's gain control to match the output of the source unit. The rotary gain control is labeled 1 to 11 and has a sensitivity range of 150mV to 5V.
Remote Punch Level Control: A wired Remote Punch Level Control is included, linked to the gain control of the amplifier. The module allows you to remotely control the output level of the amplifier from the dash or center console. The Remote Punch Level Control features a rotary dial, and comes with mounting hardware and an 16-1/2' cable.

Note: The Remote Punch Level Control measures approximately 1-3/4" wide (2-5/8" including the mounting flange) x 3/4" high x 1-5/8" deep (2-1/8" deep including the knob and wiring).

Crossover: The amplifier is equipped with a 12dB/octave Butterworth low-pass crossover. The crossover point is continuously variable from 50 to 250 Hz. This being a subwoofer amp, the crossover is always engaged.
Infrasonic Filter: The variable 15-40Hz, 12 dB/octave infrasonic filter is designed to prevent frequencies below the audio range from being applied to the subwoofer.
Punch EQ: The Punch EQ bass boost circuit is adjustable from 0 (min) to +18dB (max) and centered at 45Hz.

Connections

Power Terminals: The power and ground terminals are nickel-plated set screw terminals and will accommodate up to 4 gauge power and ground wires. (Rockford Fosgate recommends 4 AWG minimum.)

Fuse: An external 100-amp fuse (not included) must be installed on the power wire at the battery. If a wiring kit is used which includes a fuse with a value other than 100-amps, the original should be replaced with a 100-amp fuse.

Remote Turn-On Terminal: The remote turn-on terminal is a nickel-plated set screw terminal that will accommodate up to an 8 AWG wire. It's used to remotely turn the amplifier on and off.
Speaker Terminals: The two pair of speaker outputs are nickel-plated set screw terminals and will accommodate up to 8 AWG speaker wire. The terminals are internally wired in parallel.
RCA Input Jacks: The industry standard RCA jacks provide an easy connection for preamp level input. They are nickel-plated to resist signal degradation caused by corrosion.
Speaker Level Input: A speaker level input harness is included, making it easier to add the amplifier to a factory radio or to a receiver with no preamp outputs.
RCA Output Jacks: A pair of RCA pass-thru jacks provides a convenient source for daisy-chaining an additional amplifier without running an extra set of RCA cables from the front of your vehicle to the amplifier location.
Wired Remote: An RJ-25 jack is used with the included Remote Punch Level Control.

Amplifier Dimensions:

Width: 11.095"
Height: 1.978"
Depth: 7.352"

Subwoofer

Overview: The Rockford Fosgate Punch P2D4-12 is a 12-inch subwoofer with dual 4Ω voice coils. The sub features a StampCast steel frame, quick-release compression terminals, a Kevlar fiber reinforced paper cone, and Santoprene surround. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.

Dual 4Ω Voice Coils: The dual 4Ω voice coils offer wiring flexibility; when wired in parallel the woofer presents a 2Ω load, when wired in series the woofer presents an 8Ω mono load.

Steel Basket: The P2D4-12 subwoofer features a StampCast steel basket for added rigidity.

Compression Terminals: The P2D4-12 features spring post terminals which accommodate speaker wire up to 10 gauge.

CEA-2031 Compliant: Power handling on the P2D4-12 subwoofer conforms to CEA-2031 industry standards, meaning the subwoofer has the capacity to handle its rated power under continuous demand, not just for and instant.

FlexFit Basket: The Flex Fit frame utilizes slots (where possible) instead of single screw sized holes; allowing slight adjustment of the speaker when mounted.

Trim Ring: To improve the cosmetic look, a decorative trim ring is included that mounts over the flange of the woofer. When using the cast aluminum trim ring the woofer is first mounted with four screws, then the ring is placed on top of the woofer, aligning the final four holes of the woofer with ring. The other four screws are used for these holes to mount the ring and woofer to the enclosure. Without the trim ring the mounting height of the woofer is just over 7/8 of an inch, with the trim ring it's approximately 1-1/16 inches. The diameter of the trim ring is 13-5/16 inches.

Enclosure

Materials: The Sound Ordnance BB122-125S Bass Bunker is an unloaded, hatchback-style sealed enclosure for two 12" subwoofers. It is constructed of 5/8" MDF (medium-density fiberboard), covered in black carpet.

Internal Box Volume: The enclosure has two separate chambers, each with 1.265 cubic feet of airspace.

Terminals: The BB122-125S is equipped with two pair of spring-post speaker terminals, one for each chamber, mounted in the rear panel. The spring terminals will accept bare wire up to 10 gauge, pin connectors, and single banana plugs, but are spaced too far apart for dual banana plugs. Inside the enclosure, each set of terminals has an attached 21" length of speaker wire for connecting the subwoofer.

Brackets: Brackets for securing the enclosure to your vehicle are recommended.

Enclosure Dimensions:

Width: 32.75"
Height: 14.5"
Depth (bottom): 13.625"
Depth (top): 10.625"

10 questions already asked

Will this sub enclosure fit behind the 3rd row seat of a 2016 Cadillac Escalade?

teedub Oct 19, 2019

1 answer

You'll have to do some measuring on your end, I'm not familiar with the cargo areas of Escalades. I can however give you the dimensions of my enclosure. Mine runs L:15in x W:35in (my amp is on the side of the box, it would be 33in without) x H:15in. Also the back of the enclosure leans in by about 15°. As long as you have 15in of cargo floor with the 3rd row up, It should fit.

alyssa Oct 20, 2019

Is there a specific reason this package comes with the larger box? I noticed the subs recommend 1.02 cubic ft

Hey Woody. The subwoofers in that Rockford Bass package are the P2D4. They are dual 4 ohm voice coil subs rated at 400 watts RMS (800 peak). If you are looking for a different Rockford sub one of our Product Advisors can build you a custom setup. You can contact us here: https://bit.ly/2QNxGQB. --Cosmo

kristina Nov 13, 2017 (Staff)

I am confused, the information page says that wiring these speakers in series produces a 1 ohm load. I then clicked on "details" and it says wiring them in series will produce a 8 ohm load and parallel will produce a 2 ohm load. Can someone clarify for me?

grant May 17, 2017

1 answer

Hi grant I think I can help! The details are explaining just 1 subwoofer wired. When wired together you can get a 1ohm load or a 4 ohm load. Obviously a 1ohm to get the full 1200rms. I personally have this same combo,just ported. Buy this and you won't be dissapointed!!!

austin May 18, 2017

How many watts can I add to this,and can I. I want to ad d a speaker to the doors (1 per door) each most likely 100 wattswatts so 200 altogther extra at the max I'm not gonna go too crazy. Are there inputs for 2 extra speakers? I'm new to car audio Just an outdated system and I like some bass

Thanks for your question. There is nothing vehicle specific with this package. You will need an amp wiring kit, which is not included. On the product page "Accessories" tab you will find two recommended wiring kits for this package. Hope that helps.

There's no "package" we have that includes a ported box with these particular subwoofers, but if you contact one of our Advisors directly (via the "Contact Us" link at the top of the page; or by phone at 888.955.6000) then they may be able to work with you and substitute the ported box with this Rockford package. I hope that helps. My Bio: http://www.crutchfield.com/Support/Bio.aspx?bio=159

Tuning amp to subs. I have bought the Rockford Prime R1200-1D amp and hooked it up to (2) Rockford Punch P2D4-12 subs. The subs are connected so that they are on a 1 ohm load at the amp. I am looking for help on tuning the amps setting to get the most out of the system without risking any harm to the amp or the subs. I have read the steps on Crutchfield on how to tune your amp to your subs but when doing it the protect mode light kicked on on my amp. Turned off the car and started it back up 15 mins later and everything worked fine. I have played the system for about a week with no problems now just tryin to refine the system and the sound. Anybody have recommendations for the gain and frequency settings that works for them? Please any suggestions will help. Thanks
