Review: Excellent - but could not install due to shape (oval and not round) and hence to return. However, when tested the sound without installation, was an excellent quality including the build. Also delivery took more than a week - which is too long to wait.

### ⭐⭐⭐⭐⭐ Review
*by A***R on August 11, 2024*

Have a factory 15W rms stereo in truck. Other (decent) 6x9 co-ax that were recommended replacements for my door speakers required a minimum 50W to drive them. These infinity speakers transfer the power very nicely, no distortion when volume way up. The efficiency of these speakers is very impressive. Just make sure of a few things before installing in door: 1) The speakers are deeper than the factory installs. Make sure you have enough room in the door speaker enclosure. I had to jerry-rig an included spacer/adaptor to offset them enough from door enclosure rim, to make them fit. I got lucky and it worked. 2) check the connector type between the door wiring and speaker connection points. I had to search for and found (on Amazon) the correct connector before I could install them. After all that fussing around, I was pleasantly satisfied with the sound.
