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!!!
