Easy to Install. Sound great.
Kirsten from Hobbs, NM on 10/18/2022
2004 Chevrolet Silverado 2500/3500
Probably overkill with the front speakers for a small truck cab but I'm happy with the sound. I opted for different screws that have a rubber gasket. I didn't care for the clips that came with it and figured the screws I bought would keep anything from rattling.
Pros: Good sound, easy to install
Cons:

Worked great!! Sounds way better than the stock speakers.
Pros: The wiring harness kit, thumbs up.
Cons: Having to drill new mounting holes thumbs down. HOWEVER, after looking at the factory bracket, I removed it from the factory speaker, and redrilled it instead and mounted the new JBLs to it. Clipped it right in. No fuss, no muss.

Customer service was extremely helpful and highly recommended these speakers. He, and the web site, indicated they would fit in '68 Corvette kick panels. Unfortunately, the exterior width of the speaker mounting plate is exactly the same width as the kick panel opening. Consequently, additional brackets have to be fabricated and attached to the corners of the plastic speaker mounting frame, which is not an easy task because of the limited space. I was lead to believe one would just have to drill four holes and use the supplied hardware, but that would only work if the speaker frame was larger than the panel opening; which is not the case. It's a shame; they're good looking speakers and I'd really like to use them, but I'm not sure that I'll be able to.

Fits into front dash 1988 Firebird
Crutchfield customer from Chazy, NY on 12/10/2021
1987 Pontiac Firebird
Very happy with these speakers and a big upgrade from the 30yr old originals. Also they fit the driver side front, a little snug but it works great and passenger side dropped right in. Install was easy with the free supplied connectors from Crutchfield, it was plug and play with no splicing.
Pros: Good fit and high quality
Cons: None

The 4"x6" was too small for my old car even though that was the original size. The speakers appeared to be oh high quality, however.
Pros: Quality speakers
Cons: Didn't fit.

Jaydon from Glasgow, KY on 7/13/2021

These speakers are awesome and decently good bass. The only thing is at higher volumes the bass makes a odd thumping sound, though I have my bass turned up high. Fits great would buy again!
Pros: Outstanding tweeters and decent bass response
Cons: With very high bass makes a unusual thump noise but nothing bad

Love the clear sound.
Crutchfield customer from Las Cruces, NM on 1/11/2021

These speakers have great sound for replacements for the OEM's. Can't wait till I replace the head unit. I know these will be up for the higher wattage and will sound even better. Would definitely buy again for my next truck.
Pros: Great sound for the price
Cons:

Upgrade for a GMC 1500
Crutchfield customer from Berkeley Spgs, WV on 7/4/2020
2014 GMC Sierra 1500
Where to begin, bought this to compliment the 6x9 kicker installed in my front doors of a 2014 GMC 1500 standard cab pick up. The master sheet said to remove the stock speakers and replace with the JBL and drill new holes to secure. I could not find a location where I could get more than one hole to secure said speaker. That being said I had to modify the stock speaker which is no small task having to cut out the speaker and then drill new holes in the surround to mount. This took a lot of time but worked really well. Every thing else in the master sheet was spot on . After all was done sounded great.
Pros: complemented the front kickers well and sounds great
Cons: Maybe not the right speaker for the rear location in this install although the data said it was a simple swap. Maybe just not in a standard cab double or crew cab might be different .

Nice speakers, big upgrade over stock. Lack bass but they're small so wasn't expecting much. Will be adding a subwoofer in the future. 1998 Silverado ext cab. You do NOT have to completely pull apart the back interior of the truck to do these. Rear seat can stay in too.
