I switched out a stereo from my old Ford Taurus to my 1990 240SX and it was like I had never had bass before. The difference was extreme. Just //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif I was very surprised when I switched over my current stereo from my van which was doing a 144.7db in the kick to my current Taurus which is doing 145.1db in the kick. I truly expected to not be as loud. The weird part is the van had serious gains by moving it from the headrest to the dash, to the kick. The Taurus didn't make much of a difference in comparison.
