I installed this on
BMW 330Ci

Review
This woofer just rocks my ride everytime. I now face no more boring rides! Totally thankful to my relative who suggested me to get this woofer. What this woofer gives is that it enhances beats to deliver that extra vibration, and bass drops that extra awesome enjoyment! I never had any regrets getting this 15" woofers that gives me the 'life' every morning! One downside of this woofer is its size though - being 15", it may be quite tough to get a strategic location to install this ultimate speakers. You'd be rewarded, I'd say, once you figured out where to get it installed.

What I like
The awesome bass and pounds it gives.

What I do not like
May be a headache to get the perfect location to get it installed since it's quite huge.
