How to Install Tweeters without Crossover?

Wiring tweeters without crossover is fairly simple. Determine the best place to mount your tweeters before removing the nuts from that area. Then, attach the tweeter’s wires to the sound system’s wire. Once done, turn the screw and nuts to close the panel.

Things You Will Need

You need to make you have the following items at hand before you begin the wiring activity:

  • Tweeters
  • Putty knife
  • Wrench
  • Plastic strips
  • Soldering gun
  • Nuts and bolts
  • Male and female connectors

Here are the steps you need to follow to wire tweeters without crossover.

Step 1: Take All Safety Precautions Including Disconnecting the Battery

It is critical to take safety precautions before wiring a tweeter without a crossover. Otherwise, you risk encountering a major short-circuit. Make sure the ignition is turned off before entering the engine compartment.

Then, using a safety cloth, open the engine compartment and touch the battery. Next, cut the negative terminal of the battery, allowing current to flow to the stereo. The negative electrode is black in color, and it can be safely removed with the help of a wrench. You can now move on to other tasks.

Step 2: Mount the Tweeter

Determine the best place for the tweeters on the main unit, and then remove the necessary panels. You have a few basic options for mounting your tweeters.

Surface Mounting

Surface mounting involves placing the tweeter on top of the favored mounting location’s surface. It could be on the rear deck, door pillar, or dashboard. It is important that you place the tweeter in a special cup.

After that, place the cup on the surface you’ve chosen for mounting your tweeters. Some cups swivel, allowing high frequencies to be directed toward a favored listening position.

Angle Mounting

Angle mounting is a technique for listening to sound from a specific location. This method is also simple, but the tweeter will be noticeable in angle mounting, just as it will be in surface mounting.

Flush Mounting

Surface and bottom mounting are less technical than flush mounting. When a vehicle lacks factory tweeters, flush mounting is generally used. You will need to drill a hole of the same size as the tweeters you’re going to wire to flush mount them. In most automobiles, the sail panel and upper door are viable locations for flush mounting.

Using a drill with a sharpened circular blade is the best way to make the hole. You may need to soften out the hole with a knife or something else sharp after you’ve made the hole.

Bottom Mounting

With bottom mounting, tweeters are installed in pre-existing tweeter holes. Simply unscrew the grill off, plug the tweeter, and then replace the grill. It’s a simple mounting method that doesn’t necessitate the creation of new holes.

Some vehicles, however, do not have factory-installed tweeter holes. As a result, this method is limited to vehicles with factory tweeter holes.

Step 3: Wire the Tweeters

Once you’ve decided where you want your tweeter to go, detach the nuts from that location and hook up the tweeter’s wires to the wiring of your sound system. You can do this with the help of a soldering gun and by following the steps below:

  1. Hook up the tweeter wires to the head unit’s wires with the help of connectors
  2. The wires for speakers on your tweeters should be color-coded. Positive wires are usually red, while negative wires have a black stripe running down them.
  3. Hook up the positive and negative wires from the tweeters to the positive and negative terminals on the speakers.
  4. Make sure that the polarities are in the correct order, or the system will short circuit.
  5. Using a polarity connector, you can assess the connection.
  6. Then, using a soldering iron, weld the wires together.
  7. Lastly, you’ll want to put the tweeters through their paces, which means turning the power back on.
  8. You have now successfully wired a tweeter.
