WIRING CONFIGURATIONS

By varying the wiring configuration of your speakers you can create an impedance load to match your system. Altering the wiring configurations gives a range of options for impedance loads. Series, Parallel, or Series-Parallel wiring configurations are different techniques for wiring speakers that provide different loads. Series configuration is a string method where speakers are wired end to end. Parallel configuration uses two or more speakers wired across common terminals. Series-Parallel configuration combines both techniques. Choose the wiring diagram that corresponds to the number of woofers and the impedance of your amplifier.

SUBWOOFER CROSSOVERS

There are two operational types of crossovers, passive and active. Passive crossovers (coils or inductors) are placed on the speaker leads between the amplifier and speaker. An active crossover is an electronic filter that separates the audio signal fed to different amplifiers. For optimum subwoofer performance, we recommend using an active 80-100Hz low-pass crossover at 12dB/octave.

P1S4/12, P1S815 specifications

Rockford Fosgate is a well-respected name in the car audio industry, renowned for its high-performance audio products that cater to audiophiles and casual listeners alike. Among its celebrated offerings are the P1S4-12 and P1S815 subwoofers, both of which exemplify the brand’s commitment to quality sound and durability.

The Rockford Fosgate P1S4-12 is a 12-inch subwoofer designed to deliver powerful bass without compromising on clarity. This model features a powerful motor structure with a dual voice coil configuration, rated at 4 ohms. This design allows for greater flexibility in wiring configurations, enabling users to optimize performance based on their setup. The P1S4-12 benefits from a reinforced polypropylene cone, ensuring a robust output while minimizing distortion at high volumes. Additionally, the subwoofer is equipped with a high-temperature, 2.5-inch voice coil that enhances heat dissipation, allowing for sustained performance even during extended listening sessions.

On the other hand, the P1S815 is an impressive 15-inch subwoofer that packs substantial power for audiophiles seeking deep, thumping bass. It features similar technology to the P1S4-12, such as a 4-ohm dual voice coil design, making it versatile in its application. The larger cone area of the P1S815 allows for a greater air displacement, resulting in an even richer low-frequency response. Like its smaller counterpart, it boasts a durable rubber surround and a specially formulated composite blend cone that enhances rigidity and sound reproduction.

Both models utilize Rockford Fosgate's patented VAST technology, which increases the effective radiating area of the subwoofers, thereby enhancing output without increasing the size. They also feature quick-disconnect speaker terminals for easy installation. The robust construction of both subwoofers ensures that they can withstand the rigors of car audio environments, making them not only powerful but also reliable.

In conclusion, the Rockford Fosgate P1S4-12 and P1S815 subwoofers offer a combination of power, durability, and advanced technologies, making them excellent choices for anyone looking to enhance their car audio experience. Whether you prefer the punchy impact of the 12-inch subwoofer or the deep rumble of the 15-inch model, both are designed to deliver impressive performance for a wide variety of musical genres.
