Stock Corolla front speaker
Cut out the original with a dremel and used it to mount the much better Boston split system
Added some deadening
I used about 4 sheets in total. Did the doors (1.5 sheets each and the rear parcel tray. Did the outer skin and some of the inner closer to the speaker. Also the inside of the door pad and rear parcel shelf.
I replaced the paper cone 6x9's with 5.25in coaxials. Splits and sub running off a JBL 4ch amp.
The original head unit gave up so it was replaced with a Pioneer double din for USB, Bluetooth and DVD.
