P2D4-8 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 P2D4-8 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.

Awesome Sub For the Price

After some searching and trying different products, I finally stayed with this sub.

Running 2 of them in a custom ported box under the back seat in a 4-door Silverado. Great sound, excellent clarity and I cannot believe how hard they hit for 8" woofers! Pushing them with a Power T-400-2 and I have had zero problems so far. Rockford Fosgate delivers again!

Excellent 8"

Excellent sub for the size and $, but i felt it lacked the depth from the Hz freq i was looking for. It filled the gap the interior speakers were lacking but i personally wanted the deeper sound that a 10"+ sub could deliver.

Good product

I have to say Rockford Fosgate makes good equipment, BUT the down side is you see it in EVERY vehicle on the road. I have 2 Orion HCCA 15's & I have this 8 inch hidden in my center consul for mid bass.

decent

It was an ok sub but the infinity reference 8 inch is much better and has more than 4 Times the bass the sub couldn't push out any heavy bass without over extending the spider making it sound like a loud pop so if your looking for a really good 8 inch sub get an infinity reference it's less expensive and out performs the Rockford any day I have both subs and compared them infinity wins hands down

WOW!! Great sub

This sub hits hard for being an 8". The design & feel of it is more than I expected. You would think this is a 1000w sub just by the design. I just bought one & wired to 2 ohm in a ported box. I listen to classic rock, hip hop, & reggae and this sounds great for these genres. I would definitely recommend this sub.

These F'en 8's rock

had previously used with Rockford Punch 300x1;
Polk 8"
JBL 8"
Pioneer Flat 8"
The Rockford P2D4-8 kills them all...
The others did not go as low or as loud, or as well defined for a 8"
From an old school car audio designer and this is my own stuff, these 8" do the trick "very well".

Nice little sub

I just put one of these in a ported enclosure behind the driver seat of my MR2 and am very satisfied with the results. The rubber surround is very thick and requires a break in period. I am amazed at how low of notes this 8" subwoofer can hit.
