Summary: I replaced the stock speakers in my Toyota, and these sound great. I'm no expert, but I feel like the sound is much improved. The price is reasonable for this level of improvement. The only limitation is that my car isn't the quietest inside.
Pros: terrific sound at all levels of volume
Cons: extra install charge because wooden backings had to be created to fit in car
Summary: I'd like to give these 5 stars but I can't. I bought 4 to replace the OE door speakers in my 2004 Matrix with a Kenwood DNX570HD head unit . I was hoping to get a little more bass than the OEs and not have to put any money into adding a subwoofer on a 10yr old car. While the JLs definitely produce better sound than the OE speakers, they actually produce less, albeit cleaner, bass. I can't get them to produce even a hint of a thump or rumble.
Pros: Very good sound and great audio separation over the OE speakers. The JLs create much fuller sound in the cabin of the car.
Cons: Wimpy bass response. Installation screws were too long for the brackets in the Crutchfield kit.
Summary: These speakers are fantastic---just make sure you have adequate power. They need juice. Most likely a factory head unit would not be enough---I had to add a power amp to get them to sound great...so glad I did.
'08 Sierra Crew Cab - Replaced all 4 door speakers
ACE Classic Rock, Crutchfield
26 February 2014
Summary: Wow! I am happy I chose these speakers. The speakers sound great with the stock head unit. I replaced all 4 stock door speakers (front and back) with these 6.75" JL Audio TR650-CXi speakers. The whole project was simple. It might have taken an hour or a little more max. The mounting hardware needed a minor adjustment for the speakers to fit as they are setup for 6.5" or 6.75".
Pros: Easy install Clean and crisp sound on the GM stock head unit All mounting hardware and wire harnesses included when ordering from Crutchfield
Summary: very clear sounding speaker not as good as JL audio c2650 but I would recommend them. easy install you definitely need a amp to push them to enjoy the mid and the upper frequency all and all a very good speaker for the money
