Wats up guys. When in the begining i bought my accord I read the specs for the speakers and it was 6 by 9 on the back. You cant fit any 6x9 speakers into the back hole because its bigger than 6x9. What i did is the following. At first take out the little 6inch speakers from the back stock bracket. Not you got stock bracket with a hole in the middle. next I drilled my new 6x9 from the bottom of that bracked. Thna i just put it in and what i got was my stock 6x9 bracket with new 6x9 speakers conected to it from the bottom. I have pioneer speakers and they play great. Try it my way u dont need to buy nothing.
