How do you change the rear speakers on a 1992 Toyota Previa?

Answer 1

First you have to remove the plastic entry trim on the side door floor and on the rear hatch entry bottom. Then you can pop the trim off. It's held with both pop in bolts and clamps around the top. To totally remove the panels you have to unbolt the seat belts at the back. It is not necessary to remove the panels totally to remove the speakers. Once the panel is disconnected from the top and sides the speakers are accessible but will require a short Phillips screwdriver or a ninety degree angled screw driver. There are four screws in each speaker and the wire connection clips in. To replace the speakers you may have to modify this connection but it is easily done. You can use either 5.25 inch or 6.5 inch round speakers. The existing speakers are 5.25 inch. The 5.25 inch fit well but it might be a snug fit for the 6.5 inch. Once the speakers are in then re-clip the brackets and press in the bolts on the panels. If you unbolt the seat belts re-bolt them and then reinstall the plastic base trim on the doors. NOTE: Check the speaker operation before re-installing the panels.

Try to use Toyota speaker adapter plugs so you don't need to cut wires and mess the electric system up. You can get them from Ebay or Amazon.
