I ordered these speakers to replace my stock 1998 Chrysler Sebring JXI rear speakers. The system pre-install in my car included an Infinity Amp (too what power specs I am not sure), with quad 6x9 Speakers (front door, rear) and two dash tweeters. So when I bought these speakers I was a little wary of how much punch they would pack when I got them. On a wim, and from my past experiences with Crutchfield (Great service), I decided to hop on these. Once I installed them I was quite impressed with them. They pack a nice little punch to them and hit nice deep bass and the highs are good as well. Wish they packed as much punch as a 6x9 of this quality would, but that is a consumer error of mine. Would defiantly reccomend this product to others, a long with advocate the great job that Crutchfield does with all of the included free necessities you need when installing speakers and other units.
Pros: Good Highs, good lows, a good quality build, for 40 dollars? And you get everything you need to install it with the ease of assistance and help offered through Crutchfield.
Cons: Well, don't know if it happened in the UPS Warehouse or not, but it looked like package was damaged on the way, looked like a rod went through it and there was a small (<1x1 cm) rip in the surround of my speaker. However, it caused no damage to the overall quality of the speaker and it still sounds great.
