How to Make an Inline Tweeter Crossover
The tweeter is your car’s most delicate speaker. Most crossovers will route frequencies to the relevant drivers in order to optimize the power band. The tweeter must be protected from frequencies that are beneath the driver’s intended response. Herein you will want to use a capacitor to protect your tweeter’s value.
Things That You Will Need
- A 4 ohm tweeter
- An 8 microfarad non-polarized capacitor
- A soldering iron with lead-free solder
- A heat gun
- 1 millimeter of shrink tubing
- Find both the positive and the negative wires that are located on the back of your tweeter. You will find that most manufactures have pre-soldered the tweeter leads on to the back of the drivers. This makes it easier for you to be able to work with various brands of tweeters because you will always know where the positive and the negative wires are located.
- Slide part of the shrink tubing that you are using up to the top the tweeter’s positive wire. Make sure that this shrink tubing is long enough to cover all of the exposed wires that are located on the capacitor (this also includes any of the soldered junctions).
- Heat up you soldering iron. Touch your hot soldering iron and the tip of the solder to one of your capacitor’s wires and to the tweeter’s positive wire. Allow for a small bead of solder to flow over this junction and connect the two wires together for you.
- Use your soldering gun and some solder to solder the opposite end of the tweeter's capacitor to your tweeter’s speaker wire.
- Slide the shrink tubing back down the tweeter’s wire and over the top of the capacitor too.
- Turn your heat gun on low. Use your heat gun to heat the shrink tubing. Be careful that you do not burn yourself as you move the heat gun so that it is positioned anywhere from three to four inches away from your shrink tube. Once the shrink tube forms over the top of your junction, stop. You are now done as you have just made an inline tweeter connection.
