Description

Stylish sound JBL makes speakers for trendsetters, those who want a car speaker that looks as good as it sounds. Their GX328 3-1/2" coaxial speakers flaunt a contemporary look that's backed by JBL's legendary commitment to excellent sound. The speaker's patented Plus One structure extends the surface area of the polypropylene woofer cone to give you a better midbass experience compared to other speakers this size. And an edge-driven balanced dome tweeter expands the high-frequency range, so you'll hear musical details that you never heard from your old speakers. The little things that count The GX302's low-impedance design safely draws more power from your car stereo or amp to give your music extra punch. JBL has also included a tweeter deflector to compensate for the diversity of car interiors. With high-frequency soundwaves guided more directly toward your ears, your music gains a truer, more dynamic sound. A match for any system These 3-ohm speakers are sensitive enough that you can power them with a factory or aftermarket radio, but you'll get even better results feeding them power from an outboard amp.

  • 2008 Dodge Ram 2500
These speakers fit perfectly to replace the corner dash speakers on my truck. If you replace the center speaker as well, you'll have to cut just a little of the hole so the larger-than-factory speaker magnet can drop in. They work fantastically and completely changed the sound to the point where I had difficulty adjusting the equalizer to the new dynamic. My gas-guzzling truck has become my daily driver because of the speaker upgrade. I recommend purchasing connection cables for an easy and fast installation. You'll be able to replace your speakers in five minutes total ... show more

  • Slept on!
So loud for only being 3.5! Clean crisp vocals with a big punch of bass! JBL over anything! And it’s running on a standard amp can’t even imagine what they would sound like with an aftermarket amp! High quality, great power and range! Functions off wire harness for a easy installation.

  • Lexus RX 5th Gen compatible
Lexus RX350 2024 fits the front dash speakers. Just need the adapter cable. Took 15 mins to install. In and out. Does fit the second hole for screw, one is tight enough, but I used 3M automotive tape to keep it in place and prevent any vibrations noises from the plastic it’s hanging on. The sound is overall a big upgrade or the base version. The JBL vs stock is like double the size lol. I also tweaked the sound tuning. It sounds great for my current in music with K-pop. I was thinking about adding my sub back in but this kind of fill enough sound to satisfy me. ... show more

  • Replaced factory JBL dash speakers on a Tacoma
Install note: For the 2016-2023 Toyota Tacoma you need to trim the dash openings and use a self tapping screw for the forward most hole. I used a large, heavy duty utility knife and some end snippers, the plastic is relatively soft and easy to carve a little at a time. The factory grilles fit over perfectly once you get the speakers positioned. As far as an upgrade it’s worth every penny of 55 dollars. The factory JBL dash speakers had no clarity compared to these and they really livened up the theater of sound in the truck. They’re a tad louder than the others and they retain the 2 ohm impedance of stock JBL. I measured 2.3 ohms per speaker. Biggest change was better highs, some midrange and much better clarity. When listening to digital media, the sound is more theater like even with the remaining speakers still stock. I’m hearing the nice lows from the doors now too, this will keep me happy until I have the means to build something special. ... show more
