Just changed the front speakers in my dash. From 4 to 6.5inch components. They actually fit haha. However they're still no louder.. I get that they don't have a proper enclosure so wouldn't have much depth but how come they're so so quiet. I've tried different decent head units.. No difference. Has anyone any ideas? The only thing I haven't tried is new speaker cable as haven't had chance. Or do I need to amp them? I'm not worried about depth like that as have a sub anyway Cheers
