they would produce more bass especially if you get an amp for them. but regular speakers should not be used to produce a lot of bass you normally cut off the bass at a certain frequency on normal speakers and then you would get a subwoofer to take care of the lows.
your never gonna get that much bass from coaxial or component speakers. they are usually crossed-over around 80 hertz. subs are needed for anything lower. they will sound a lot clearer then your stock ones, can't say whether they will have more bass though.
