Hi, start my audio system from scratch, KICKER S15 L7 with alpina mrp-2000 amp. Hifonic 4x175 amp for speakers, 2 channels for underseat sub, 2 chanels for mids and tweeters. one audio seller recomend my gladen bmw one speakers set. They are plug and play 2 tweeters, 2 mid's, 2 underseat subs. I received all I need to start. I ready to install the amplifier for speakers but when I look at the mids speakers magnets they looks so small and I start to wondering why I need amp for them and why he recomend my them if he knows to I want to amplify them. And those speakers are designed for plug straight to head unit as they "plug&play"
Or I don't know something ???
