2g rear speaker question

ok well i dont really like the sound of my rear speakers or the look was wondering if 6x9 speakers would fit inplace of the stock ones and if its really hard to do..    thx

okay i tried to fit a pair of planet audio  6x9's i n the back the didnt fit really well you will have to modify the brackets a bit i used a die grinder and they didnt interfer w/ my top when i open and close it so yeah you can switch them out but if your complaining about the crackling thats just how they are the stockspeakers suck and the fronts will do it to so you ill want to replace them too 

My memphis 6x9s came with a plactic bracket. Im pretty sure I ended up getting all 4 holes to line.
