So the factory Clarion head unit in my 1999 Infiniti i30 was dying. The lights continued to be dimmed, the bass was muted, and the high notes of many songs were loaded with harsh static. I'm very glad I chose PAC! The sound quality is phenomenal and crystal clear. I liked that the wires were already partially stripped at the ends. The worst part (for me at least) of installing a new head unit is having to strip and then connect all the wires. Thank you for making this tedious process a little less annoying! I would definitely recommend this brand.
