This document is a user manual for Cerwin Vega Mobile Stroker and Stroker Pro Series speakers, specifically the ST6SC and SPRO65C models. It provides comprehensive information on installation, features, and warranty, guiding users through the process of setting up and maintaining their car audio system for optimal sound quality.
The primary function of these devices is to reproduce high-quality sound within a car audio system. Designed and engineered by Cerwin Vega Mobile, these speakers aim to deliver great sound quality for many years of listening enjoyment. The manual emphasizes the importance of proper installation to achieve the best performance, highlighting that the speakers are designed with flexibility for various installation locations within a vehicle.
For usage, the manual details several key features. It strongly recommends professional installation by an authorized Cerwin Vega Mobile dealer, who can expertly assemble/disassemble vehicle interiors and ensure ideal speaker placement for sound quality. However, for those opting for self-installation, the manual provides thorough instructions.
One crucial aspect of usage is speaker mounting. The manual explains the necessity of isolating the front sound waves from the rear sound waves for optimal performance. This is achieved by securely mounting the speaker to a flat surface, or baffle, and ensuring a tight seal to prevent air leaks around the frame. For vehicles with existing factory speaker locations, replacing them with the same size speaker is the easiest method. If no factory locations are available, users are advised to carefully select the best possible locations, ideally equidistant from the ears, to achieve the best results.
The manual also covers "Door Mounting" for installations not using factory locations. It instructs users to remove the door panel and check for clearance before cutting, ensuring that the window operation remains unobstructed. A critical recommendation for enhanced sound quality is to apply a sound deadening mat to the door "skin." The manual states that a more "damped" car will ultimately sound better, indicating that reducing vibrations and resonances is key to improved audio performance.
"Rear Deck Mounting" is another installation method described, offering both top (interior drop-in) and bottom (underneath trunk securement) approaches. Both methods require a good seal around the frame for optimal performance.
"Running New Wiring" is addressed with important safety precautions. When new wires are required, especially through metal sections like door jambs, the use of grommets is essential to prevent damage. Running wires through bare metal is strictly prohibited as it can damage the source unit, amplifier, or even the speakers themselves. The manual stresses that protecting wiring against short circuits is the most important installation concern.
The manual includes detailed illustrations for connecting the ST65C component system (with SPRO65C having the same connection method) to an amplifier. This includes connections for the midbass driver, tweeter, and the crossover.
A significant usage feature is "Crossover Programming." Each ST65C / SPRO65C component system comes with model-specific adjustable crossovers, allowing for attenuation and phase adjustments. The tweeter adjustment offers settings for -2dB of attenuation, 0dB, or +2dB of gain. Additionally, a "Phase switch" is included to correct acoustical phase issues that may arise from driver placement within the vehicle's environment. This feature allows users to fine-tune the sound to their specific vehicle and listening preferences.
"Tweeter Installation" provides guidance for flush or surface mounting tweeters. Users must ensure the desired location can accommodate the required hole sizes and depth. The manual describes using provided hardware to mount the cup, snaking speaker wires through the cup, connecting the tweeter to the wires, and gently snapping the tweeter into the cup. A warning is given not to push on the center of the tweeter grill.
"Crossover Installation" explains that passive crossovers should be installed in a well-ventilated area whenever possible. If installed in doors using factory wiring, the crossover should be placed behind the door panel to avoid water damage from rain or moisture. It also advises against placing crossovers near factory wiring looms to prevent radiated noise problems. The manual details connecting the "INPUT" side of the crossover to the amplifier's speaker output terminals, observing correct polarity. Then, the "WOOFER" terminals connect to the midrange speaker, ensuring protected and secure wiring. Finally, the "TWEETER" terminals connect to the tweeter, again emphasizing correct polarity and careful handling of the smaller gauge wires.
A unique feature mentioned is the "RAF" (Rear Acoustic Fill) output on each ST65C or SPRO65C component crossover. This output allows an additional speaker to be powered off the same channel without affecting the impedance load on the source unit. The RAF output has a pre-determined attenuation of -10dB, designed to create a more realistic stereo image and a larger sound stage, enhancing the overall listening experience.
For maintenance, the manual provides warranty information. Cerwin Vega Mobile warrants its amplifiers and speakers to be free of defects in materials and workmanship for one year from the original purchase date from an authorized dealer. The warranty is non-transferable. If service is required due to a manufacturing defect or malfunction, Cerwin Vega Mobile will repair or replace the product at no charge.
The warranty does not cover damage caused by abuse, accident, misuse, neglect, modifications, repair attempts, or misrepresentation by sellers/installers. It also excludes incidental, consequential, or cosmetic damage, as well as the cost of removing or reinstalling the product. The warranty is void if the product's serial number has been removed, defaced, or tampered with.
For warranty claims, users are advised to contact their authorized Cerwin Vega Mobile dealer. All warranty returns must include proof of purchase (original sales receipt copy) and be shipped freight prepaid to the facility with a clearly marked Return Authorization (RA) number on the package exterior. Direct returns from consumers or non-authorized dealers without a valid RA number will be refused. International purchases are covered by the respective country's distributor, not by Cerwin Vega Mobile U.S.A.
The manual encourages users to register their new product to receive benefits such as product notifications, confirmation of ownership, and access to knowledgeable customer service and technical assistance. Registration is voluntary and does not diminish limited warranty rights.
In summary, the Cerwin Vega Mobile Stroker and Stroker Pro Series speakers are designed for high-fidelity car audio. Their usage involves careful installation, precise wiring, and optional fine-tuning through adjustable crossovers and unique features like Rear Acoustic Fill. Maintenance is primarily covered by a one-year limited warranty against manufacturing defects, with clear guidelines for claims and exclusions. The manual serves as an essential guide for maximizing the performance and longevity of these car audio components.
