Rockford Fosgate P2 Series Subwoofer

2 Punches and You're Out!!

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 400 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 P2D4-10 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.

It punches alright.

The following review is for P2D4-10, which is a part of the bundle you are viewing.

Have this in a .77 sealed box at 2 ohms and 500 watts rms and it takes it well. I can feel the bass hit through my seat into my chest or it will rumble my mirrors . Stick with what you can rely on, fosgate is a high quality company that will last.

This thing punches hard when needed and rumbles low when asked.

Sounds great with all genres of music. Very happy. Oh and way cheaper here on Sonic than crutch field.

They pound hard!

The following review is for P2D4-10, which is a part of the bundle you are viewing.

I have two of these in a custom built sealed box, about 0.63 cubic ft for each sub. Got them wired to a p500-1 at one ohm and crossover at 100hrz. MAN, do they pound! Not only that but they sound good with all kinds of music. Rock, dub step, jazz you name it, it sounds good. I had to put three layers of dynamat on the trunk to keep it from rattling. Buy these and you will not be disapointed! By the way the p500-1 is a perfect amp for a set of these. My birth sheet said 721 at one ohm.

Great Sub!!

The following review is for P2D4-10, which is a part of the bundle you are viewing.

I have this 10" sub in the trunk of my Honda S2000 and I absolutely love it! It hits the low notes very well and clear with Alpine Deck and Amp. I wish this came with a cage cover though! Great buy!

Great Deal!!!

The following review is for P2D4-10, which is a part of the bundle you are viewing.

I have this one 10 in a .7 cubic foot box powered by a Rockford r250x1d mono amp in a hatchback mustang. It sounds great with all types of music. I mostly listen to rock and rap and it has yet to disappoint.

Rockford P2 Subwoofer

The following review is for P2D4-10, which is a part of the bundle you are viewing.

I installed this subwoofer in a ported box in my Honda Accord. Its powered just right by a RF Prime r250-1 amp. This sub is excellent. It adds an excellent lower end to all my everyday music. The sound quality is incredible. It resonates very well in my car. Also, if I want to turn it up and make some street noise, I have the gain remote that came with the amp, and it can slam if you need it to. It drops the jaw of whoever hears it at loud volume. People are quite surprised to see that it is only 1 10. My one complaint is that it doesn't hit the lowest of lows or the highest of highs, but I believe that may be because of the enclosure. Great buy! Don't think twice.

Awesome Sub, Awesome Price

The following review is for P2D4-10, which is a part of the bundle you are viewing.

The title pretty much explains it. It's a great all around sub, plays well with rock, rap, country, you name it. I currently have one of them running off a fosgate p300 at 2 ohms in a ported probox. Yes, a ported probox. Don't let people fool you on this prefab. At least with this sub, it gets very loud when you want it to. Sounds like two tens, and has very good sound quality. It's very durable too, I've been beating on it for 3 months & it just keeps pounding! It took me about 3 weeks to fully break it in, but once it did, man.. For a single 10? It's crazy to me. Even out of the box it's impressive. I've demo'd this sub & people's really impressed at how much bass it puts out for a 10 and how musical it is. If your just looking to upgrade your sound, this sub has exactly what you need, low space requirements & for a low price at Sonic that's very hard to beat. I highly recommend it as I recommend all fosgate products from the punch 2 series & up, great quality, great budget sub definitely.

Rockford P2D4 In Dodge Ram 2500

The following review is for P2D4-10, which is a part of the bundle you are viewing.

This is a very good sounding sub in the box under my rear seats. It hits all the low notes without any distortion. Plays all types of music well and does not fade after many hours of driving. Sounds great inside the truck for all seating positions and cannot really hear it outside the truck, which to me is great.

I installed this sub and a 300 watt amp in an enclosure on my boat. It added the right amount of oomph to the bass.Good value sub for the price.
