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 2011 Punch Stage 2 series will crank out 250 watts of RMS power handling, giving you that nice deep base with out 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 braking the bank.

 
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.
