• intros：{"brand_intro":"Rockford Fosgate（来福）成立于1973年，是美国汽车音响的'炸机'鼻祖，以'大功率、高灵敏度、极致低频'著称。创始人Jim Fosgate是车载功放技术的革新者，发明了'Punch EQ'动态均衡电路。来福在低音炮领域拥有'VAST'（垂直附着悬边技术）和'Dual Voice Coil'等专利，产品以'能炸能听'闻名。品控方面，每台低音炮需通过'Punch Test'（连续满功率运行4小时）验证。P300系列是其有源低音炮的经典型号，被誉为'入门炸机之王'。","product_intro":"Rockford Fosgate P300-12是一款12英寸有源低音炮，灵敏度高达91dB，内置300W Class-D功放。核心卖点是'暴力低频'，能输出低至25Hz的超低频，且声压级可达130dB以上，适合嘻哈、电子和摇滚乐。其'Punch EQ'功能可一键增强低频冲击力，配合'Remote Punch Level Control'（有线遥控），驾驶者可随时调节低音强度。相比JBL和阿尔派，P300-12在低频量感和冲击力上碾压同级，但体积较大（需后备箱空间）。","key_specs":{"灵敏度":"91dB（1W/1m），高灵敏度配合大功率功放，轻松获得震撼声压","额定功率":"300W（峰值600W），Class-D功放，效率高达85%","频率响应":"25Hz-150Hz，下潜深度同级领先，能还原超低频冲击","尺寸":"12英寸低音单元，箱体尺寸（430×360×330mm），需较大安装空间","阻抗":"4Ω，标准汽车音响阻抗，支持桥接或并联"}}
