Summary: I install these speakers in my 2008 Crown Victoria Police Interceptor. When I installed My new Sony MEX-XB100BT Stereo I waited 2 weeks before I installed the JL Audio Speakers. It Sounded great with the Ford factory speakers. When I installed the JL Audio Speakers, WOW What a difference.
Summary: for all these people on these reviews for any brand speaker complaining about bass, why don't you do some research and learn that these speakers are not whatsoever responsible for good bass. that is what a subwoofer is used for. These speakers sound great, crisp, and clean.
Summary: I had these speakers installed in my Ford Explorer in 2002 and ran them in that until last week (2013) when I moved them to my newly purchased 1997 Crown Vic. They still sound great, and I'm not considering buying anything else.
Pros: Long-lasting, great overall sound even without a sub or amplifier backing them up
Cons: They do seem to get noisy at high volume, but I can't say it's not due to the age of these speakers.
Summary: I bought these JL to install in the rear doors of my 07 F150 FX2 Super Cab. It took longer to take the door panel off than it did to replace the actual speakers. The sound output is a major improvement over my old stock speakers. Very crisp highs and decent, clear mid bass.
Pros: Very easy to install, perfect fit for my vehicle. Good, clean sound reproduction.

Summary: These speakers put out what you put into them. They are clean and clear and lacking in the low-mid mud that plages so many audio speakers. They do not do what a nice sub would do but still provide good bass response.
Pros: Fairly flat and articulate response that is orders of magnitude better than factory original equipment.
Summary: I purchased these as an upgrade for my stock speakers in a 2006 Mazda 6. I installed them and ran the factory stereo. Initially I was quite disappointed. They sounded under-powered and the sound quality was overall just poor. No base, mids were crappy, highs so so.
Pros: Sound awesome if you upgrade from stock stereo
Cons: Didn't sound worth a darn from factory stereo
