Summary: I'm no audio expert but to me these speakers sound clean with the Kenwood radio I installed at the same time. The factory speakers were blown (cranked 1812 Overture up a bit much) and I fried the front panel of the stock radio. I'm still trying to get more mid-range from them and can't pin down if it's my radio settings or the bass blockers that I installed since I also installed an 8" powered sub.
Summary: Great sounding (budget) speakers. Universal installation for most applications. I was hoping these would work in my wife's 2001 Acura Integra, since it came stock with component tweeters. Despite the amount of different mounting methods, it was quite difficult to make these work, since I had to use the factory grilles (since the Kenwood bezels were too small for the hole in the door panel.
Summary: I installed these in my 1998 Grand Prix GTP today. I could not get the tweeters to fit right so I just hooked up the original ones and they sound great. The woofers sound so much better than the original speakers (from 1998). They sound better than the 6.5" pioneers that I had installed in my 03 cavalier by far and I'm impressed with them.
Pros: Great sound, clear, nice looking, easy install
Cons: Could not get tweeters installed without drilling hole in door panel (Crutchfield said they would fit in factory location but they didn't fit)
Summary: Sweet set of Clearance Speakers! I love Kenwood Sound! I highly recommend these speakers!
Pros: Crystal Clear sound and good depth too! Best part! They fit in all the stock spots that are in the vehicle already so no crazy cutting and building going on! Car still looks factory new! Awesome!
