These Speakers replaced some older Kenwood's KFC-C6882IE models. These were installed in a 1998 Ford Windstar Mini Van in the Front Doors. For 4 me, a Huge Improvement. The HI's are Higher and Cleaner and more crisp, and the BASS (again for me) was Much Improved, nothing that would Blow you away but enough that I noticed it right away. Controls all set Flat for Comparison. However when the Bass was mover by just 2 click towards "More", it was a Huge difference compared to the Kenwood's. Not Boomy, but Solid and more distinct. They seem to move more AIR, I am "not using" enclosures either. I Play a Variety of music, Country, Rock, Classic Rock, Rock N Roll, and some Classic Motown. It all sounds better through these Alpine's by a lot.... I hear things that I wonder what was that, and it was stuff that I hadn't heard through the Kenwood's. I am using the Same Receiver / Deck / Head unit, a Kenwood KDC-X492 22W with No Amp, and No Sub. Have Older Pioneers in the Rear that really don't do much but replaced the original Ford Junk. You can find them cheaper else where, however, Crutchfield Treats there customers like no one else, so the Little Extra is no Biggie. Shipping was Fast and Packaging was Perfect. No Damage to anything. For the Bucks, these are well worth it!
Pros: Sound Great.
Cons: None that I can find after working them out for a Couple weeks. However, It should be Noted here that I did have to Spend some Time Buzzing out two Holes on Both Speakers because they "were Not" a remove and replace and your done Job. It took me and extra 20 / 30 Mins of back and forth to get the Mounting Holes to Line Up. Wasn't much fun having to do that I would have to say.
