Rockford Fosgate Punch P1S4-15 Punch P1 15" 4-ohm subwoofer

The P1 Series continues Rockford Fosgate's world-famous line that is considered to be "The Woofer of Choice" for car audio systems. The P1S4-15 subwoofer has a peak power rating of 500 watts and an RMS rating of 250 watts. Just like all Rockford Fosgate products, this subwoofer is built with quality and durability. The P1S4-15 features a high modulus Kevlar reinforced paper cone with a high-density NBR half-roll surround. The 10 AWG nickel-plated push terminals keep a secure connection at all times while resisting corrosion. The Punch Series 15" woofer also comes equipped with 2" 4-layer high temp voice coil, poly-cotton spider, extended pole piece, bumped backplate, and a proprietary spider venting/cooling technique that helps keep the subwoofer operating at a safe temperature. Once again, Rockford has made a top-notch product at an affordable price.

While built on a long-standing history of performance, the punch series woofers can deliver not only the 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

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.

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.

Stitched Tinsel Leads

To improve 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.
