Ok, so I decide to put pioneer 6x9" speakers from my dads car into mine since he doesn’t even use them. So I take his off and everything is going fine until I get to mine. I get into my trunk and see that the rear speakers are very small and poorly wired. The speakers were also pioneers but they were 4" or 5" speakers. The idiot that owned the car before me was too cheap to buy 6x9s so he put 4" or 5" speakers in the rear, no wonder it sounded like shit. So I took out the plate that was holding down the small speakers and realized that the hole in the plate was too small for my 6x9. Just so you people would know what I’m talking about, here are some pics.
Old speakers compared to my 6x9s
The plate holding the old speaker down
The plate with the speaker in it so you would get the idea
My question is since this is my first time doing this, was there ever a factory plate designed to hold the 6x9s? Where can I get the plates or is it best to customize? My car is an lx 94
