A good little speaker that does the job and improves the sound in place of your stock speakers. Produces a cleaner sound over stock, handles highs & lows better than stock. If you want performance, or are critical in terms of your sound, these are not the speakers for you. If you want a crisper, cleaner sound as compared to the factory speakers in an older vehicle, or a plain-jane ordinary factory system - these will be a marked improvement, and ideal for the price. I installed in a 2000 Mercury Mountaineer with the Ford MACH sound system. The factory speakers are enclosed component speakers (tweeter/woofer). These Sony's out-produce the highs, and are equal to the mid's, and weeker in the low range. I installed them in the front only. I would not swap out the rear speakers with this speaker. Not enough bass. These speakers will work nicely as front speakers, and combo them with a better speaker with a bit more punch in bass for the rear speakers. Overall, they leave me thinking "Not a bad set of speakers for the price, I'm quite pleased". Install was easy, direct fit for my vehicle, no modifications, used existing harware, Crutchfield install sheets were helpful. Wiring harness supplied by Crutchfield did not match, no biggie. I just spliced my connections with wirenuts - a couple extra minutes, no problem.
Pros: Clean sound, easy to install, direct fit, noticeable improvement over factory paper speakers, handles a fair amount of power and remains clean sounding.
Cons: Bass is a little weak. But for the price, I can't complain.
