Getting a true, musical lower register out of your car's audio system ain't easy. Lower-quality systems sure are loud; but how much idiotic in-car "boom, boom, boom" can you stand?
There is news in the lower registers of car audio.Personally, I like what I am hearing from a new matched subwoofer and amplifier: the Hertz HP 1 KD in-car audio amplifier and Mille ML 300 Subwoofer from Elettromedia. (Price: TBA)
The system puts out an even, balanced wall of sound that is dimensional and crisp, like a full raging waterfall. Not bad for a unit that sits under the seat of your car.
