I installed this on
Citroen C4

Review
This item is what an audiophile would want one of his component missing, the woofer - the equipment that pounds the car frames with kicking bass. Found out about these Ground Zero GZRW 10XD-AL from my friend as he was sending me home the other day. When he started the car, and as the sound system comes to life, the amazing sounding bass was what captured my attention. The Ground Zero GZRW 10XD-AL gives off crystal clear, no distortion bass, along with powerful pounding and kicking low tones. Something audiophiles would love to get.

What I like
This powerful woofer gives off the most luxurious bass, along with its pounds and kicks, definitely any audiophile's ear candy.

What I do not like
Expensive since this woofer is pretty high end.
