When I started replacing my Toyota Camry 2002 Car audio system, I had no clue about anything. If I could give my clueless self advice, the most important thing would be to read about and prepare for the entire process first, don't just read the first step thinking you'll wing it from there. Winging this tends to end up scratching or breaking parts of your car. Luckily I didn't do too much damage.
• A head unit (CD Radio) with a USB connector is nice, but many of today's models
work with 4GB or 8GB USB sticks max. 16GB sticks (or more) may not be fully compatible.
• 3-way, 4-way speakers are a marketing gimmick. Either get a quality 2 way coaxial Speaker or
preferably component speakers. Components will be much harder to install but they sound
better because they come with separate woofers, tweeters, external crossovers, all three of
which will have to be mounted separately.
• Toyota Camry uses 6"x9" speakers in front and back. 6"x9" component sets are generally not
made since round component woofer cones offer superior sound quality. An adapter plate
(baffle) will therefore have to be made.
• A separate amplifier drives quality speakers, increasing their volume without distortion. In my
case, an amp was a must because I wanted to also install quality rear speakers for kids in the
back, so I ended up having the head unit powering the rear speakers and an amp powering the
I was told it was not a good idea to install components in both front & back. It's better to install
components in front and 2-way coaxials in the rear. Try to fade the rear speakers whenever
there are no passengers in the rear to get the optimal sound out of the front component
When looking at Speaker sensitivity, high sensitivity is better for a low-powered factory radio.
Lower sensitivity may be a better for a higher powered replacement you buy.
To summarize: The quickest and easiest thing to do is to just replace the front speakers with
2-way coaxial speakers. (Coaxial means tweeter and woofer come in one unified enclosure.)
Doing more means entering a world of pain (j/k for some, true for me ).
To get to Front Speakers, there are 6 screws to remove.
1. Remove screw #1 and #2 located on the bottom of the door.
2. Use a small screwdriver covered with tape (so as to not scratch anything) or use a plastic
knife to pop out this round hole plug to reveal screw #3:
3. Carefully pop out this little plate inside the door handle to reveal screw #4:
4. Remove this black rubber bottom to reveal screw #5:
5. Removing screw #5 will allow you to pop out the entire Power Window Master Switch
Assembly to reveal screw #6.
6. Disconnect the Power window and door lock harnesses.
7. Remove this black sail panel triangle, it pops right off:
8. Pry the bottom of the door Panel away and pop out these 7 clips one by one:
To get to Rear Speakers:
1. You're supposed to "hold up the seat and disengage the clips to pull out the cushion
assembly forward to remove it, being careful to hold the clips around the roots."
There are two of these, on on the left side, one on the right, I put my two hands to feel these,
then pulled up with some force:
2. Lift this on both corners to reveal a 12mm metric bolt.
[I also used this bolt to also ground my amplifier.]
3. Once you remove the screw, lift this up to remove it:
4. Lift this up to be able to pull the back rest toward you.
[When you put it back, push it in so it clicks.]
5. Use a screwdriver covered with tape (so as to not scratch anything) or use a plastic knife to
pop out this roof side garnish on both left and right sides:
4. Pop out these 9 clips to remove this Room partition Board Assembly:
5. Before removing this Package Tray Trim Panel assembly:
6. Stick your hand under it to disconnect this Brake Light assembly connector:
[I don't have the XLE version with Rear Window Shade but they say there are 2 extra clips that
are bolted down from the top, under the rear window shade. Apparently, you're supposed to
pull hard up and out on the Package Tray (Rear Deck) until it pops out.]
Pop the dashboard cover to disconnect the small 2 1/2" speakers (they only have 2 5/8"
clearance in the mounting bracket). They may ruin the sound of your new side speakers.
