it all depends on what you want to spend. over there gear is alot cheaper than here in aus so you have better options. if you want it 'concealed' but want to be able to hear it-doubt you will if those side pipes are straight through!- i would use components or seperates as they will let you place the tweeter just under the dash or in the kick panels directed towards you but the mid ranges can be hid away a little more.

a good audio shop should be able to give some more guidance.
