I installed this on
Honda Civic

Review
Installed these Ground Zero GZUW 8SQ woofers. They were slightly expensive for my liking, but after getting the 'sneak peak' of it on my friend's ride, I had definitely love them. Now, after 6 months of using it, I find that it was definitely worth every cent. It produces a crystal clear tone, along with excellent low toned bass with maximum pounding. It doesn't feel 'weak' as compared to some others which after some time, the vibrations and pounds coming from the woofers get weaker. Mid and high tones are delivered well, and I must say I have enjoyed these 6 months having this woofer installed in my ride.

What I like
Excellent low toned bass that pounds, along with great sounding mid and high tone delivery.

What I do not like
Expensive for any average driver's liking.
