    Thank you Frodoz, where would you start if it was you? Pull the door and look at speaker connections first? I don’t believe following the wire from the dash speaker to door is going to be an easy task.

    After a good look around under the left outboard kick panel since someone's been in there already. Probably...and it's a little easier than pulling the A/B pillar, lower outboard and dash speaker covers first. There are good videos for all though.

    This is what happens when you trust a company to do good work. I get remote start installed and few weeks later find out my door speaker doesn’t work. Thanks to Frodoz, I took off the kick panel and found that it appears speaker wires were cut and then taped together to pigtail the cut with addeded wire. I have to believe this is where my issue is coming from. I am looking it further now but take a look at the pic. Pay attention to the bright blue wires that are NOT OEM. I would go back and complain but I can’t prove anything now since it’s been a few weeks.

    Not all installers are created equal...and most depend on referrals. If your installer is a legitimate Business, go back to explain why you are there, show them the print and what you found. They should be more than willing to correct their mistake...but remember to be nice. Everyone makes mistakes. ;)

    I have no problem with mistakes, it’s when people hide them. If they would have said I accidentally cut into your speaker wire, but fixed it no problem. They also did not even solder the connection. I’ve decided to just try and fix this myself than deal with aggravation.

    Only problem is he cut the wire at the point where the ends have the color markings so I can’t tell which one goes to violet end and which goes to pink, so I might blow out the speaker if I connect it wrong.

    Use the prints, plug and pin numbers to chase the wires...maybe even pull the door panel to isolate the speaker (disconnect) and use your meter. I'd still at least talk to them first. Like I said, most DEPEND on referrals for their business. Wish ya luck and let us know how it turns out.

    Well I tried to reconnect them with solder on the end coming from the door and then switched each line of the speaker wire and still no sound on eithier side. I’m guessing they fried the speaker? I have a meter, just not well versed in using it. Can I test the ends of the line somehow?

    One more question, I’m assuming the signal is coming from the BACK of the pin I have pictured, and then routed to the door?

    Unlikely a fried speaker. You won't wreck one by hooking it up with opposite polarity. Far from it. It'll just have crummy sound and weird dead spots of almost no sound at all in the car.

    I suggest following the line into the door, get the card off and see what they've hooked it up to on that end. They've done one end of this wire with poor termination. They might have been consistent...

    Important...First verify this is the right connector! There are more than 1 each wires that are pink or violet in this car. Although they may have pulled the plug number label off the cut end, you can look to see if there's a label behind the J-side...where it plugs into. I'm only guessing this is connector/block LI1 (if you are on the right one) because I believe connector/block OL2 is the door feed through. Then, or if not labeled, disconnect the speaker wires which should be identified with solid pink and violet insulation at that end (or pink + and violet -)..."per the print". Check continuity from there to each wire you exposed behind the kick panel going to the door. The lower speaker on page 2 of the print is the door speaker by the way. You identify which is which using the ohms Ω setting on the meter. Touch both meter leads together before so you know what continuity looks like on yours. Give us a yell after that.

    If polarity is reversed speaker will be out of phase; no imaging nor staging.

    Thank you for the responses, I don’t have time today to take the door off. I can’t see why the termination at the speaker would be screwed up if it is still the factory speaker. Thank you Frodoz, I will tackle this in a couple days.

    The speaker end wasn't messed with, but you need to isolate (disconnect) the wires to check them...and you don't want to shoot 9 VDC through the speaker if it's still good...because that's what the meter does when you check for resistance/ohms. Just let us know.

    One last for now. Cap or tape those exposed car side wires separately before closing up. If this is the wrong plug, you don't need a not wire bouncing around behind the kick panel.

    Thank you, I capped the wires and hope to tackle this more tomorrow when I have time between work and the kids!

    Something I was thinking about, if there is no signal going to the speaker, should I then try and tap into the other side of the connector where the wire comes in where it is routed from the dash speaker? I guess the break could even be before that connector as well though, which is why I will have to test with the meter.

    Isolate and identify the problem first. You said the squawker works so stick with page 2 for now. The door panel is easy to remove. Provided thread link will help...and there are a lot of videos if you Google...How to remove 2010 door panel. 2010-2015 are essentially the same for this.

    I took off the door and found a COMPLETE HACK job. I have to take back what I said about the installation company, this all had to have been done by previous owner. This speaker was obviously removed at some point. There are no screws and it is attached by some type of glue, I don’t even know what it is. The connecting clip to the speaker is gone, and the speaker is directly connect with speaker wire. The wire is not taped soldered or anything. I don’t even know where to start with this, besides prying the speaker off. Please see the attached butcher pics.

    I tested the speaker with the wires that were attached to it with my meter on ohm setting and did not get a reading. Tested the wires coming from the door to speaker no reading, I tested all of this on the ohm setting and switched to test opposite sides all on ohm setting, not sure if I’m doing it right. I tested the speaker with a battery and it moves.

    Yep, that is the sort of consistency I was worried about.

    Toyota rivets their speakers in, which is great in the sense that they never rattle out loose, but bad in the sense that if you have to remove the speaker for any reason, you must drill out the rivets. I just went through this, did a full speaker replacement in ours. Somebody apparently needed to remove these speakers, and chose to glue them back in. Tough to tell what it is by look, but it could be ordinary bathroom caulk.

    While you've got the speaker out, root around in the bottom of the door to see if they've left the backing shanks of the old rivets or any other litter in there to rattle later.

    I still can’t figure out what’s going on with no signal. I connected the wires and have a solid connection in the kick panel and at the speaker. I reversed the wires and still no sound? Could the speaker still be bad if it moves when I attached the battery to it?

    If you put voltage across a speaker coil and the cone moved, then the speaker works. It may not be perfectly healthy, but it's enough to make sound when presented with a signal instead of just voltage. You probably heard a tick, thump or pop when you put the battery on, and that's normal. Therefore I suspect it's still a connection problem.

    Put your meter probes on the same contacts you put the battery on- you should get around 4Ω. If you don't get anything, carefully examine these contacts and make sure you're hitting the same points. After that we have to start making sure your meter works.
