Rockford Fosgate P2 Series Subwoofer

P2D2-8 Punch P2 Series Subwoofer

When it comes to car subwoofers, Rockford Fosgate raised the bar in terms of high quality affordable subwoofers. These Punch Stage 2 subwoofers are the perfect combination of price and deep bass. The new Punch Stage 2 series will crank out 250 watts of RMS power handling, giving you that nice deep bass without over powering your audio system. The face of the woofer has been upgraded with a kevlar reinforced paper cone that will provide durability and great sound quality. For those long sessions of hard hitting bass, the rubber surround has been manufactured to handle high excursion movements through out the day. With their patented technology the Rockford Fosgate P2D2-8 are the perfect match for those looking for quality bass without breaking the bank.

While built on a long standing history of performance, the punch series woofers can deliver not only output to satisfy you when you want it loud but maintain a level of sound quality for when you really want to "listen" to your music. Taking many design cues from the Power Series, Rockford Fosgate engineers continue to improve the Punch Series year after year making it one of the most sought after woofer lines for music and bass enthusiasts alike. With features like Dual tear & fatigue resistant poly-cotton spider for high strength and anodized aluminum voice coil formers to handle heat buildup in the motor structure under full power situations, these drivers are designed to perform.

 
Anodized Aluminum Voice Coil Former

Anodized Aluminum Voice Coil Former

By using an anodized aluminum voice coil former on their subwoofers, Rockford Fosgate is able to dissipate heat from the voice coil more efficiently. A hot voice coil can melt the adhesive bonds, which will lead to eventual subwoofer failure. The aluminum voice coil former acts as a heat-sink to dissipate thermal build-up on the voice coil cool during high SPL conditions.

 
CEA-2031 Rockford Fosgate Subwoofers

Conforms to CEA-2031

Rockford Fosgate has built this subwoofer to conform to the CEA-2031 loudspeaker power handling industry standards. This means that you can trust the subwoofer to have the capacity to safely handle the continuous (RMS) power rating. Having a CEA-2031 power handling is important when matching a subwoofer to an amplifier because the power ratings are accurate.

 
Rockford Fosgate Stitched Tinsel Leads

Stitched Tinsel Leads

To improve the reliability and performance by reducing fatigue and possible shorting, Rockford Fosgate has stitched the tinsel leads to the spider. The multipoint periodic stitching lead wires reduce the mass of the tinsel leads to spread the stress over a greater area. This improves the reliability and performance of the subwoofer.

 
Rockford Fosgate VAST Surround

VAST: Vertical Attach Surround Technique

In order to increase the surface area of the cone without causing any installation issues, Rockford Fosgate designed the Vertical Attach Surround Technique (VAST). By redesigning the manner in which the surround adheres to the basket, these speakers gain up to 25% more effective radiating cone area. This improves the nominal efficiency and maximum output.

Subwoofer Specifications

Subwoofer Series
Each subwoofer manufactured is part of a series. This is the name of the subwoofer's series.
Punch P2 (Rockford Fosgate)
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
8"
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.
500 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.
250 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.
Dual
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.
2 ohms
Voice Coil Diameter
Diameter of voice coil, usually measured in inches.
2.25"
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).
39.6 - 250 Hz
Sensitivity
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".
83 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.
5.8 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.
Black
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.
Kevlar Reinforced Pulp (Paper)
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.
Rubber
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.
Optional (Accessory required and sold separately)
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.
No

Recommended Enclosure Specifications

Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

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.

Ported / Vented
Sealed
Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.20 cubic feet
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.
0.23 cubic feet
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
0.30 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.
0.65 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.
4-3/4"
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.
7-1/8"
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.

No

Electromechanical Parameters

Free-Air Resonance (Fs)
The free-air resonance frequency of the subwoofer, measured in Hz. At this frequency the weight of the moving parts is perfectly balanced with the subwoofers suspension system.
39.6 Hz
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.
9.9 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.
0.46
Electrical Q Value (Qes)
The subwoofers relative damping (Q) at the resonance frequency (Fs), including electrical losses. Also called the mechanical damping of the subwoofer. The unitless measurement usually varies from 0.5 – 10.
0.51
Electrical Resistance of Voice Coil (Re)
Amount of DC resistance of the subwoofer when measured with an ohm meter. Typically, this will read less than the impedance rating of the subwoofer.
3.40 ohms
Mechanical Q Value (Qms)
This is the subwoofers relative damping (Q) at the resonance frequency (Fs), including mechanical losses. Also called the mechanical damping of the subwoofer. This unitless measurement usually varies from 0.5 – 10.

Very impressed

December 2, 2013

I have a single cab 1st gen S10 this means no room. Went from a shallow mount 10" to one of these mounted in a custom sealed enclosure between the buckets. driven off +/-200RMS this little guy is incredible. great extension both high and low, I'm asking a lot of it trying to fill the mid bass gap left below the cutoff of my 6.5" comp set and it hasn't let me down. Great motor strength (compared to the usual commercial brands) and the low end extension is fantastic. I'm primarily a 70s/80s punk rock listener that likes to get gangster at times. To you this means I ask this sub to do everything imaginable, I originally thought I should order 2 but I'm happy with the one. I should say I'm incredibly impressed with the single. At this price it should be junk and it just isnt.

If I can say one bad thing, The push terminals are a bit tough to get larger gauge (10 and up) wire into, just because of there location. You have to get the angle just right to avoid fraying the wire when pushing it in.

Great sub for small places!

November 8, 2011

I got two of these subs to put in an old Subaru. I didn't want to take up too much space so I looked up the specks for them from Rockford and built two 0.65 cu. ft ported boxes tuned to 38 Hz. Got them hooked up to an old Rockford amp I had laying around, it pushes about 200w to each sub. All I can say is, WOW! These things hit hard and low. Never had any sub less than a 10 so I was shocked by how much they bumped. You will not hear them from a block away but in the car you will feel them. All this for less than 1.5 cu. ft. of space for both boxes! I have bought and used lots of different brands of car audio produts over the years and I am always blown away by Rockford. The amp on these things is almost 10 years old by the way. Take the time to build the right boxes for these 8 and they will deliver some great sound.

Great subs i bought two of these and with my kicker zx500 amp these run great. There really loud and they make my car rattle sometimes. At my high school many people think i have 12's and when i tell them there only 8's there really surprised. My advice don't go cheap when buying subs or amps or box and also wiring it all makes the difference in your audio system. Only con is you might need a capacitor.

2010 dodge ram - Best 8" sub so far!! For the $$

January 7, 2012

So I bought 2 of these, 1 for each vehicle I own. Firstly I want to say I've tried JL w3 & w1's, infinity and the MTX 8's. This by far is the best 8" I've ever owned! That's not to say a jlw7 won't beat this but that's a whole other price range. This thing hasn't been broken in yet and it POUNDS hard and low! I installed both of these 8's into a Digital Designs DDE-E1508 enclosure which I bought 2 locally for $150 and can't beat the quality! There slot ported enclosures at .72 volume. If you're looking for an 8" at great price this is it!! Rockford makes a great product especially the new 2011 power line with this punch p2! I have this p2 sub with the 6.5" components for front and the 6x9 in rear of my 2010 dodge ram, all purchased here at the best price!

picked up two of these bad boys for my 94 Nissan hard body, built two sealed enclosures to spec, and they sound great!
they give you that repetitious punchy/slapping bass!
very clean sound for the price, i paired the two subs up with a mono block 500 watt rms Rockford amp.

Best Answer: Hello,

Unfortunately, the answers provided thus far are a bit inaccurate. One P2D2-8 will be wired up to 4ohms or down to 1ohm. Which means the amplifier you choose much provide ~250w RMS @4ohms or @1ohm. The Rockford Fosgate Punch P500X1BD, however, provides too much power at @1ohm and not enough @4ohms. The intended match is the Rockford Fosgate Punch P400X1. http://www.sonicelectronix.com/item_67772_Rockford-Fosgate-Punch-P400X1.html

Best Answer: Technically, yes. This amp will be able to power this sub just fine. As the sub is rated to handle 500 watts, be sure to wire it correctly (parallel) so that it will come out to 1 ohm. This will provide 500w of power to the sub. Also, TRUE 8 gauge wire is definitely a fine choice. Some companies advertise their product as 8 awg, however the actual copper wire found inside is somewhere around 10 awg. My recommendation is a 6 gauge kit with a 40 amp fuse. I personally do not know what a "vampire clip" is, unless you are referring to alligator clips. Which in this case is a bad idea. I would run power direct from battery, ground it to the metal wherever you plan to mount the amp, and run a separate remote wire to the remote terminal. Easiest way to do this without messing with the headunit is to find a fuse in your fuse box that only receives a signal when the car is RUNNING, not just electric only. Finally, if you do wish to add an aditional p2d2-8, this amp most likely will not be powerful enough to handle the load. I would find an amp that is 750 watts peak at 2 ohms, or around there. Wire both up in parallel, then make it a series load to the amp. If you don't know what that means, SonicElectronix has many wiring diagrams you can check out. Best of luck!

Best Answer: This sub hits awesome! Put one in a sealed enclosure behind the seat in my Toyota pickup and it thumps! Easily handles the 400 watts I'm sending it and is very tight punchy bass zero distortion awesome value!

Would 70 watts at 4 ohm be to much getting a nvx 900 watt amp 5 channel and how do you wire these?

Best Answer: I used a 4 channel Rockford Fosgate amp, I so not recall the exact model. Mine are @ 90 watts and sound amazing. As for the wiring, you'll need standard female spades, the large one for positive and small one for negative, there's no crossover with these it all wires up directly to the 6.5, the tweeters have different mounting options. Hope this helps.

Can I use this amp, and just use for subs now and then add components? or use door and not subs? and will this drain my battery, dim lights, etc... If it helps, I've got a red optima battery? [Moderator Edit: Fixed punctuation.]

Yes. But please give our sales team a call so that they can make sure your figures and plan match correctly.

-and will this drain my battery, dim lights, etc... If it helps, I've got a red optima battery?

That is impossible to tell. We don't know the current state of your electrical system. Generally speaking, it will likely Not dim/drain/etc..

Best Answer: Hello John,

Please do some homework on WIRING SUBWOOFERS, it will make my response easier to understand. I've also added a few links to help.

ONE Subwoofer on ONE amp will work because a DUAL-2ohm subwoofer can be wired in SERIES to a 4ohm load.
