Son, a speaker is for the mids and highs. NOT "bass you can feel". 30-45hz is what you hear coming from a vehicle, a concert, and from your next door neighbor.
For "bass you can feel", you need a single 12" or a single 15" sub around 1,000 watts RMS, a good quality ported box and a monoblock.
Loud "bass you can feel" is around 40-55hz. That's what you and your buddies feel inside the car bumping through your body. 25-35hz is what annoyed people are tired of hearing at a further distance.
They just usually complain about cars with LOUD subwoofers and LOUD exhausts.
