2 of 3 customers found the following review helpful: Great sound, complicated install, 2007-06-26 I always loved the sound and bass from Pioneer speakers and subs, and still do. But some idiot decided to remake the outside edge of the speaker. The smaller Pioneer speakers now come with a plastic rim to mount on the outside of the speaker (bad idea) This plastic retainer is held down by some microscopic screws. I don't think they can withstand the constant vibration over time. Hopefully mine will. If you want an easy install dont pick these speakers, If you don't mind duct taping your woofers they're a sure bet for great sound.
