Review: Best set of speakers to fit into and replace oem Subaru liberty GT my10 dash mid range speakers.
Review: Good set of speakers, definitely raise some hell especially when you see how tiny they’re when you open the box. I have these a the kicker 6 3/4 in both of my trucks, even did the same set in my cousins truck. Using these series of speakers in 3 trucks tells you they’re good value for the money, an everyone comments how good my trucks sound when they hear it.

### ⭐⭐⭐⭐⭐ Review
*by R***P on 2 November 2025*

Beautiful upgrade over my very old and crusty OEM speakers in my 2004 Honda Element EX. The sound is rich, warm, and well-balanced, just the way I like it, perfect for classical music, jazz, and crooners, which I listen to most. They also handle electronic music surprisingly well, and the bass is solid! I spent weeks searching for the right speakers, and these definitely do a fantastic job. At this price point, it’s hard to find better! Highly recommend!
