• intros：{"brand_intro":"来福（Rockford Fosgate）是美国汽车音响传奇品牌，成立于1973年，以制造大功率、高可靠性低音炮闻名。品牌创始人Jim Fosgate是汽车音响功放技术的奠基人之一，其发明的Punch EQ电路至今仍被广泛使用。来福的铁氧体低音炮采用独家VAST（垂直附着悬边技术）和蜘蛛网弹波，能承受极高功率，是SPL（声压级）竞赛的常胜将军。品控标准极为严苛，所有产品需通过军规级震动测试。","product_intro":"P3系列是来福的经典无源低音炮，采用12英寸铁氧体磁铁单元，额定功率600W RMS，峰值可达1200W。核心卖点是极致的低音力度和声压，适合追求'炸机'效果的重度玩家。需搭配外部功放使用，适用于后备箱倒模安装。相比JBL和阿尔派，它更偏向竞赛级性能，低频冲击力远超有源炮，但安装复杂度也更高。","key_specs":{"单元尺寸":"12英寸铁氧体磁铁，超大磁路提供强磁场控制力","额定功率":"600W RMS，峰值1200W，适合大功率功放驱动","频率响应":"22Hz - 250Hz，下潜极深，可重现超低频","阻抗":"双4欧姆音圈，支持串联/并联灵活接线","安装深度":"190mm，需较大箱体容积（建议1.5立方英尺密封箱）"}}
