The factory speakers in my 2002 Chevy truck were shot. Called Crutchfield for replacement speakers. They recommended these and they sound great. Thanks

I'm a 67 year old women who changed out old back speakers with these. My son just came to visit and we got to rock out together. Brilliant!

Upgrade for a GMC 1500

Crutchfield customer from Berkeley Spgs, WV on 7/4/2020

2014 GMC Sierra 1500

Verified customer (What's this?)
Verified employee purchase (What's this?)

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.
