Montero 3rd gen radio install

[DenTar]

So I had a similar issue that may or may not help here.

About 4-5 months ago I also installed a Pioneer double din into my 2001 Montero Limited. Followed this very thread when doing the install. I believe it's an NEX 2440 or something close to that. I will note that the speakers were working fine as was the unit.

Everything worked great until about a month ago. Went to start it one morning and the battery was dead and the speakers stopped working. Jumped it and went on my way. Next morning, same thing (dead battery). I did not know that age of the battery (I've owned the truck about a year and a half and the battery itself had no date that I could see) so bought a new one.

Will officially cut to the chase: the amp was burned out. Specifically, the actual connector to the amp had burned off one of the pins to the amp itself. Connector itself was also burned, quite badly. Will let you know that as part of my upgrade (and what I had done just a few days before this whole thing started) was install new speakers in all 4 doors. Shame on me for thinking the old amp could handle that stuff.

I have since installed a new amp and ended up splicing the speaker wires that can be found under the interior pieces by the left rear door to the new amp. Even installed a subwoofer. Thing sounds really great now.

Here is what I used to get to the old amp: https://www.mitsubishi-forums.com/threads/2001-montero-access-rear-speaker.13738/

And this one was also very helpful, as it has wiring information: https://mitsubishiforum.com/forum/m...o-sport-14/2004-montero-complete-audio-47585/

I ended up buying a 5 channel amp and a boxed sub. I did not replace the factory sub as others have done, though that would be pretty simple once you remove the panels. I will say the original sub was toast as well.

Hope this helps. Happy to provide more info. if needed but the two links above worked great for me. Thanks.

I just installed a new head unit so I thought I would do a write up on how to do it.

I purchased a jvc double din,

mainly because I like the look of a double din better as opposed to a single din but also because the previous owner had a double din and already switched the placement of the climate controls...sadly he put the stock infinity head unit back in before selling it to me.

None the less, if you would like to add a double din heres a video on how to get the center console out so you can lower the climate controls to where the tray is. On a side note If you have a dvd player then you probably dont need to watch it.

How to Remove DVD Player from 2004 Mitsubishi Mon…:
Here is the harness you will need to buy in order to install an after market radio.

Metra 70-7003

Metra 70-7003 Radio Wiring Harness for Mitsubishi Amp Integr
Heres how I did it.

First thing I did was wire the metra 70-7003 to the jvc harness. I did this the night before so it would be plug and play the next day. Usaually I would use crimp wire connectors to tie the 2 harnesses together but instead I just went old school with some electrical tape

Unhook the negative battery terminal

Unscrew the 2 screws above the compass/clock

Use a plastic panel tool to remove the surround, start on one of the bottom corners as it will come off easier

Unhook the hazard light harness from the surround and set the surround to the side

Remove the screws from the head unit and tray, set the radio and tray to the side

Attach your ground first so there are no issues with frying anything. I chose the left side of the dash bracket as the right side already has something grounded to it and I didnt want any problems

Plug the metra harness into the factory harness, make sure to align the amp integrated cable when plugging in

Plug the harness into the new head unit. Make sure that you plug the rca cables into the correct outputs on the back of the head unit

For the antenna, there are 2, so I just electrical taped off the small cable and plugged in the large one "sounds great even with a broken mast". Im not sure if taping it off matters but again I didnt want any problems after the install

Tuck the cables back in there and fit the new head unit. After this its probably a good time to hook your battery back up to make sure it works like it should

Put the surround back on and enjoy.

A couple problems I had on my specific truck that may help you if you encounter the same problems.

I had installed aftermarket led headlights prior to the new radio, when turning on the headlights while having the fm tuner on i got nothing but static from the stereo. I found out this was due to the driver/ballast of the leds. I pulled the leds and threw in some halogens and the radio was Crystal clear. For me I would much rather have a nice stereo as opposed to nice bright led headlights.

Another problem was with my factory sub. I noticed after putting in the new head unit its not working. Im not sure if it has never worked or is caused from the metra harness. Im still trying to figure that out.

Anywho, I hope this helps get some new stereos installed in your rigs!!!

I know this post is over 8 years old, but man I wish the pictures worked. This thread is still very helpful though!
