Which port and i want to put the speakers in the rear is it possible to put 4 6x9s and disable the fronts ?

 

why do you like 6x9
with the set up i have told you about you DO NOT NEED BACK SPEAKER !
i think you need to sell the bmw get a kia then f--- it up with 6x9's

 

i have heard 6x9's only 2 of em and they were seriously loud , i want something to match with the amount of bass i will have in car, dont want the bass to be more then the speakers , because i have heard that car with too much bass and less sound from those 5.25 inch Bose n the start to distort after volume 20. So i was thinkin if i put 4 6x9's n amplify them will make it better ? Will it or these 5.25 speakers should be changed with other components which are also 5.25 but non-amplified btw which are hard to find .

 

only 6x9 in the back is gonna suck ***** just put some 5.25" components in the front and you will be fine.... the back speakers is only if you want to be nice to the passengers and give em tunes.. other than that theyre useless

subs 1000watts rms will just just fine just turn the amp down a bit and its gonna give you a nice sound that wont drown out your front end. personnaly i would go sealed if you dont want boomy bass i tryed both and sealed sounds nice i did 2 ported box so far and the notes are to narrow i find anyway have fun gtg to work
