You'll have to custom-mount tweeters or midrange speakers, which usually requires drilling holes and running new wires.

Transform your sound

JL Audio's TR050-CT 1/2" textile dome tweeters can add focus and detail to the sound of your car's stereo system. Your music's high-frequency content plays an important part in creating a lively musical experience, especially in forming a strong stereo image. A well-placed set of tweeters can transform the sound in your vehicle.

You can flush- or surface-mount the TR050-CT tweeters in any convenient location. Ferrofluid cooling allows these tweeters to handle high-powered music and still maintain their smooth, clean sound. JL Audio includes in-line high-pass filters.

Audi A4 experince

Crutchfield Customer Review (What's this?)

I bought these speakers because the right tweeter failed, and they looked
like a good fit. I was able to install them in the stock location by making a
replacement for the original spring wire retaining clip sized correctly for the
JL speaker. I soldered the factory wires to the speaker. The repair took
1.5 hours for both speakers. I had the spring wire, but most hardware
stores have it. With the door panels in, the car looks stock.

I have already replaced the stock subwoffers with the JL 6W0-4 6 inch
ones, chosen because they fit behind the stock rear deck with only minor
mods. They were an improvement, and with the tweeters the system is
upgraded from a decent (bose) factory system to a really top end system,
very similar in fidelity to my BMW M5. I really recommend this entire
upgrade. The stock Audi speakers fail in most of the cars, and the entire
upgrade, woofers and tweeters costs less than one speaker from Audi.

I am very happy with JL

Product Research


Tweeters: The TR050-CTi is a pair of 1/2" textile dome tweeters with integral phase plugs and powerful, ferro-fluid cooled and damped neodymium magnets. The tweeters come installed in flush-mount fixtures. For surface mounting, the flush-mount fixtures simply slide into the surface-mount fixtures. The tweeters do not swivel or angle in the flush-mount or surface-mount fixtures.

Tweeter Mounting Dimensions:

Mounting Fixture Mounting Depth Mounting Height Frame Diameter Cutout Diameter
Flush Mount 0.6"
(.6875" screw depth)
0.341" 1.792" 1.578"
Surface Mount N/A
(0.75" screw depth)
1.083" 1.837" N/A

Crossovers: The TR050-CTi tweeters use electrolytic capacitors on the in-line 1st order high-pass filters. The Polyswitch electronic tweeter protection circuit is designed to minimize the possibility of tweeter failure. It monitors current going to the tweeter and will disconnect the tweeter from the signal when it senses overload. Once the volume has been reduced, the protection circuit will reset itself automatically.
