Removing rear subwoofer / rear deck - Toyota Nation Forum : Toy

If the alarm system has a battery remove it otherwise removing the car battery for a while may reset it. In emergency contact your local toyota dealers mechanics department and they may be able to help you at no cost.
If you put a general enquiry on google you might get lucky, do not be too specific. i.e. toyota 1994 alarm reset procedure

hook speaker wires to the amplifier output, can't use from the radio wires because they used a not smart design using one wire output from radio to amplifier, the amplifier output is connected to your soeakers, a simple check, use 1.5 battery to speaker and check the speaket, should move, or hook to some cd player output, easier that way

if you have checked all your fuses try tracing the wiring back to fuse box last time i had this problem it was in the wiring just out of the fuse box

I just replaced my blown sub in my Avalon xls with a Kicker 07C84 and it works great. For the same price of a repair kit, you can just buy this new speaker. Why go through the hassle of repairing a 9 year old speaker. This speaker fits into the same cutout of the old speaker. All I did was splice the red and black wires within the factory plastic housing so I could still use the factory connector.

i need a color grapgh map of the wireing for a pioneer raido to a toyota avalon.
