So, it seems normal? I don’t feel the bass from every songs, it sounds more like vibrations and not that hard hitting bass. It could also be because I have a weak amp? (MTX XThunder X1000D and Pioneer DEH-X5900BT which has 2v preamp outputs; a 4v+ preamp is noticeable, right?)
40 Hz is actually a little higher than I'd use for a 12" driver with 19mm Xmax, destined for car audio duty. But it sounds like perhaps the LP filter on the amp is set a little too low. That, coupled with the big peak at low frequencies caused by a peaky box and cabin again could result in that "tractor driving down the street" sound like that I love to hate about most car audio setups I've heard.
You have the box in a sedan? They are often difficult.
37hz may very well be what the tune is. A bit high perhaps.
Also, car audio fans often wants to be loud. Then they play rap. It vibrates and flexes, perfect for demos.
I noticed that Steve Meade often have rock in the background while installing caraudio. But in the car he plays rap or bass tunes. It is simply easier to play 30-50hz in a car than 60-80hz. The car has loads of cabin gain under 50hz. But often 60-70hz is weak unless played with midbasses up front (or at least not in trunk). So most people use the music that impresses in a demo situation. Hearing a car that really has power all the way from 30-80hz is quite impressive.
