These Hertz EBX 300 is definitely something a hardcore audio junkie would want to have, would need to have. They pump and kick like no other woofer that I ever had. I don't know much about setting up audio equipments, in which my brother handled those; I'm only the one who enjoys the thumps. Be prepared for headturns though, especially morning rides to work, where the bass boost from the woofer escapes out of the car. A tip though: Play good music, or you'll get horned at.

What I like
Provides awesome bass boost to the stereo system.

What I do not like
Not cheap at all!

I have always been an audiophile, and which audiophile would want one of his component missing, the woofer - the equipment that pounds the car frames with kicking bass. Found out about these Hertz DBA EBX 300 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 Hertz DBA EBX 300 gives off crystal clear, no distortion bass, along with powerful pounding and kicking low tones. Something audiophiles would love to get.

What I like
Kicking pumping bass.

What I do not like
Being high end, their costs are steep.
