can i fit 6x9 into MY 94 WRX without having to hach it around and are the old speekers easy to get out

 

I had to remove the rear seats (bolts at the bottom).
Then access the rear shelf from the boot and remove the under plating. I simply replaced the old speakers and grills with a set of MB Quartz (Tweeter in the centre) £150.00. I hid the crossovers in the side pods of the boot and they fitted in brilliantly. They sound warm and add clarity to the whole system
Try that
