If you have a Suzuki Jimny up to 2011 (or later) you probably noticed the very bad sound quality of the original sound system. The bad quality is not from the receiver/player but from the low-end Sanyo speakers included on the car and the absence of rear speakers. This tutorial will teach you how to install the rear speakers.
To preserve the original factory warranty this installation will not alter the electric cables, the car body or the holes for fixation.
Since we don't want to change the original characteristics of the vehicle, there are not many options available for the speakers. The original mount has a very limited short space and shares most of it with cables form other systems of the car.
The original player is a Clarion unit is limited to 14W RMS per channel (max 30W). If you want to install an auxiliary MP3 port on this radio, please check this article.
When choosing the new speakers I recommend to look for parts with the closest power rates from the CD player. If a lower power speaker is selected you'll notice a lot of distortion on higher volumes. If a speaker with high power (for example 100W RMS) is used the player will not have enough power to move the cone leading to a very low volume play.
On my Jimny I used a Bravox brand 5 inch 3-way speaker model B3X50. Each one of the speakers from the kit have 40W of RMS power, very close to the capacity of the Clarion player. A 0,75 mm² cable is OK for this rated power. The combination of the Selenium brand I had installed in the front of the car and the Bravox at the rear gave a good range of high and low frequencies.
The Bravox holes fit exactly the original Jimny body holes.
Materials and tools
Pliers (for the terminals)
Small electric terminals (can fit inside the original Jimny rear sound plug). If you can't find these terminals you can insert the wires directly inside the connector.
4 metal sheet screws (3mm x 10mm)
1,5m of 0,75mm² sound cable.
0,5m of 0,75mm² sound cable.
Pair of 5" 4 Ohms speakers
This installation requires you to remove the screws that hold the safety belts.
DO NOT FORGET TO TIGHT THESE SCREWS AFTER THE INSTALLATION OF THE SPEAKERS! Double check that.
