2015 Ram 1500 Crew Cab

Written By Darren, Indiana on Monday, October 19, 2015

Crutchfield Customer Review (What's this?)

Installed in the dash corners of my 2015 Ram 1500 Crew Cab with the factory Alpine system.

Pros: Included adapters from Crutchfield snaped right into place and made this literally a 10-minute job with great results. I also disconnected the center speaker, which provides a much clearer "sound stage" separation in the truck.

Cons: None in my case, overall very happy with the product and improvements.

Great Highs & Lows for dash speakers

Installed in dash of 2014 Mazda 6. Great fit and great sound. No distortion at all.

Pros: Price, sound

Crutchfield Customer Review (What's this?)

Bought these for my Tundra, knowing they probably wouldn't fit. They didn't, but they did fit in another truck I have. Easy to install and the sound is exactly what you would expect from JL Audio. High quality, excellent sound and a great value.

Crystal clear

I used these for my dash speakers in my saab convertible. They are very crisp and produce amazing sound even at high levels. I recommend using bass blockers to get the most out of an unbelievable speaker.

JL audio 3 1/2 inch speakers

Written By JL center channel 3 1/2 inch speaker, Texas on Tuesday, May 06, 2014

Crutchfield Customer Review (What's this?)

Sounds amazing, replaced all speakers in my 2010 Toyota Tundra Crewmax, only needed one to replace the factory dash center channel speaker. Puts the factory speaker to shame, sounds amazing, trying to figure out if it's possible to install the other one next to the existing one on my dash bc I have the extra room. If possible it's going to sound awesome, never knew how much just that center channel speaker made a difference. If your looking for a 3 1/2 inch speaker this is definitely the best one, sound is crisp and amazing

Pros: Sounds amazing compared to stock center channel speaker, best 3 1/2 inch speaker out there. Must buy if your needed to replace one this size

Cons: None

Awesome Speakers

Written By zach, woodland ca on Saturday, February 08, 2014

Crutchfield Customer Review (What's this?)

These have great highs! Running off a stock Tundra stereo, and they flat scream! Very little distortion.

Pros: Great sound! Good price! Can be run without a high power stereo and still get great sound.

Cons: Had to cut to fit dash speaker opening to fit. Not the speakers fault.

Amazing sound!!

Crutchfield Customer Review (What's this?)

Installed in the dash of my Mazda CX-9 to replace the factory tweets. What a difference these made! The sound stage is much improved, the sound blends so well. Also installed with 600 Hz Bass Blockers. Again stupid easy install.

Pros: Sound stage is where is should be now. Easy install. Beautiful speakers and sound.

Cons: None

Good speakers

Written By Steve1640, Madison Heights, VA on Monday, July 08, 2013

Crutchfield Customer Review (What's this?)

Speakers work nicely and sound very good. Easy to install as well! I also used the correct Bass Blockers for the install and these tweeters sound awesome!

Pros: Great balance of treble sound for my system.

Fits great in the dash, not so much in the back

Written By Luc, Denver, CO on Tuesday, May 28, 2013

Crutchfield Customer Review (What's this?)

After replacing the head unit and door speakers in my 2007 FJ cruiser, I realized that the remaining speakers were 8 ohm. After doing some research, it looked like the ones in the dash were an easy replacement with 3" speakers like this - and that they are. After removing the old speaker and the bracket and trimming some plastic off the back of the stock grill, the speaker drops right in, matching the stock bolt holes. Very easy. Looking at the speakers in the rear pillars, the installation appears to be similarly easy. Don't be fooled.

As far as sound goes, I used some Bass Blockers to cut out everything under 600 Hz, so these are effectively high mid/tweeters. They are running only off the deck. Sound is clear, perhaps slightly over-bright, but with good reproduction. I think that when I get things re-balanced with some better 6x9s in the doors and a bit of dynamat I will appreciate them more, but for a 3" speaker, they have a surprising amount of oomph.

Pros: Decent size, good high end tweeter function, not too deep.

Cons: Did not fit in the rear pillars like anticipated. Buyer beware - when replacing stock speakers, be careful of what space you have.

Crutchfield Customer Review (What's this?)

Installed in 06 Jeep commander, fast easy, great upgrade. I enjoy alot of 90's hip-hop with classic instrumentals and the stock speakers couldn't bring the sound to a good level for me. These definitely did it for me and at a reasonable price considering all the information crutchfield floods us with as far as instructions and wire harnesses. All in all an awesome experience for me I definitely recommend these I had to get 4 door upgrades as well great for this particular vehicle model.

Pros: Easy installation, dramatic sound.

Cons: None


Written By Smith, Iowa on Wednesday, January 23, 2013

Crutchfield Customer Review (What's this?)

I mean ya.... they are okay speakers... but i cant hear them at all against my subs or any of my other speakers... i would amplify them but the head unit already powers them at their max wattage so I could really take em or leave em. So basically either I've done something wrong, or they just aren't loud enough for me. Didn't fit in my 2000 Dodge stratus very easily; had to work hard to get them in since the screw holes were off-kilter.

Pros: Crisp sound

Cons: Quiet


Written By mark, W. Bloomfield, MI on Friday, June 05, 2009

Installed in the dash of an 06 Commander. Took about 10 minutes with the
wire harness and they sound great.

JL Audio TR350-CXi

Written By Robert, Haughton, Louisiana on Wednesday, December 03, 2008

Crutchfield Customer Review (What's this?)

I like the sound of the speakers, but it is too tall to fit in the factory spot under the dash in my 1984 Chevy C/10 truck. It makes the dash have a bulge. I'm going to have to modify something. I would have give it a higher rating if it would have fit properly.

Great for small openings

Written By Lance, Houston, TX on Wednesday, September 10, 2008

Crutchfield Customer Review (What's this?)

I just installed 4 of these in my 07 Toyota FJ Cruiser and wow what a difference. I was amazed at the sound quality from such a small speaker.
Installation was straight forward. A very nice product.

Product Research


Woofers: The JL Audio Evolution TR-series coaxial speakers feature injection-molded, mica-filled polypropylene cone woofers with 3/4" voice coils and symmetrical-roll spiders. The woofers use polyether foam surrounds for reliability and strength.

Tweeters: The speakers have 1/2" treated textile dome tweeters with an integral phase plug and powerful, ferro-fluid cooled and damped neodymium magnets.

Crossovers: The TR-series coaxials use electrolytic capacitors on the 1st order high-pass filters. The woofer is unfiltered, using its engineered smooth roll-off characteristics to blend with its tweeter.
