So, as the thread title says, I have a 2006 Camry (non-JBL) and just ordered some new 6x9's for the rear. OEM one's got damaged after removal of dry-rotted covers (kids love to play with exposed speakers). What I need to know is, do I need to buy adapter plates for the new speakers, or can I just drill new holes? And before someone asks, yes, I have new covers for the new speakers.
