• intros：{"brand_intro":"来福（Rockford Fosgate）成立于1973年，是美国汽车音响领域的\"发烧级\"品牌，以\"大功率、高保真\"著称。创始人Jim Fosgate是车载功放技术的革新者，发明了\"Punch EQ\"电路和\"Constant Power\"技术。来福的产品以\"炸机\"级低音闻名，是北美改装车展的常客。品控上，来福坚持\"军用级\"标准，所有功放需通过-20°C至80°C环境测试。在中国市场，来福是高端玩家的首选，尤其受喜欢重低音和声压竞赛的车主追捧。","product_intro":"来福 P300-8是一款8英寸有源低音炮，定位\"发烧级入门\"。核心卖点包括300W RMS输出（同级最强）、Punch EQ电路（可提升6dB低频增益），以及独特的\"Conex\"悬挂系统（减少失真）。适用场景为追求大动态、高声压的用户，如听摇滚、金属或电子乐。相比JBL和阿尔派，P300-8在功率和低频冲击力上碾压同级，但体积更大（需后备箱安装）。其优势在于\"即插即用\"的发烧体验，无需额外功放。","key_specs":{"低音单元尺寸":"8英寸（20cm）阳极氧化铝盆，高强度耐高温","额定功率":"300W RMS（峰值600W），D类功放，效率>85%","频率响应":"35Hz-120Hz，可调低通滤波器，支持Punch EQ增益","箱体类型":"倒相箱（带双导向管），低频效率提升30%","安装尺寸":"380mm x 280mm x 100mm，建议放置于后备箱"}}
