I have installed speakers and a subwoofer in my 2011 Toyota Sienna and I got some feedback for this vehicle:
Front Speakers: Very awkward size, I would highly recommend getting the Speaker Adapter Plates for this vehicle that convert the speaker to 6 1/2″
Rear Speakers: Rear speakers are 6 1/2″ but they are a very shallow speaker. The factory speaker’s magnet is about 2″ round and actually goes into a 2″ hole into the frame.
Also, be very careful about locating speaker wires because there is a black/yellow twisted pair that appears to be speaker wires but is actually the SRS Airbag Power Supply. Use Caution and a Multimeter.
my 2011 toyota Sienna radio is not playing AM/FM stations. Are there any quick ways to resolve?
Marc, thanks for the 2011 Toyota Sienna speaker installation information contribution!
