I think my car sub is not putting out very much low bass. No matter how I tweak the eq and sub levels all I get is very loud bass with not a lot of "feel". I have 1 12 inch JL audio sub with a JL Audio amp. I had been under the impression that these are pretty good subs, but I have been disappointed. My cerwin vega lw 15 in my house plays noticeably lower than my car sub, and it the cerwin is only rated to 28 although I doubt it even gets that low. I have tried the same parts of songs in both my house and the car and sure enough, in the car those low notes disappear. I have never tweaked with the dials on the amp itself, so I wonder if that could help although I would have no idea what I'm doing. This sub to me is the very definition of boomy. It's too loud on most bass notes, and doesn't play the very low notes at all.
