s13 fastback speakers
 

i have a s13 fastback and have some questions regarding the speakers
first off i seen people say you can buy brackets to mount bigger speakers in the front but i wanna go with clear sound quality so was hoping anyone has some concrete advice.....i know this has been covered before but i just wanna double check because i have a fastback and wanna know the size to the front and rear speakers and if going bigger size will compromise clear sound quality thanks
