DIY Upgrade CX-5 Bose tweeters

[Lanjiao]

Difficulty: Easy

Things you need:

1. Soldering iron
2. Audio grade MKP 6.8uf capacitors (matched pair)
3. Tesa tape (to prevent rattling)
4. Insulation tubing (for the capacitor’s lead)

Remove the A pillar and tweeter, desolder the original electrolytic capacitor (take note not to overheat it. You could melt the plastic).

Replace the capacitor with audio grade mkp capacitor. You get a more detailed high frequency and smoother sound.

Any mkp capacitor works. As for how much improvement depend on your choice of capacitor.

This mod is very low cost with a good result.

Careful of the size of capacitor you choose, if it’s too big you won’t be able to put the A pillar back.

The capacitor i used has 20mm diameter (there’s still extra room for bigger capacitor).

Enjoy the music.

What model years does this mod apply to? Can I do this on my 2014 w/ Bose?

Any year and models work. The rule is simple. As long as you replace electrolytic capacitor to mkp capacitor will get a better result or no difference. You won’t make it sound worse for sure.
