The Infinity Reference 9623i's are installed in my 1998 Chrysler Sebring limited convertible. Install was fairly easy. The front right and front left speaker chassis have to be cut for the proper installation of the 9623i's. The back right and left speaker require no modification, so the 9623i's just slip right in.

For sound quality they are ok, not the best speakers in the world buy they put out good sound for the price. The bass output in these set is great, specially if amplified, just with a head unit u´ll miss half of it´s potential. The mids and highs are ok, a little on the harsh side. Not to natural sound but powerful. It´s an ok set with a good price/performance ratio.

These speakers are awesome, you really need an amp to get everything out of these speakers. But once an amp is put in place watch out, the quality really shines. Great bass, and really crisp highs. Infinity has done it again, with a great product, that performs really well and looks good at the same time. And at such a good price you can't go wrong. And of course Sonic Electronix is great, amazing service.
