Infinity  Reference 9623i

great speakers have them running off a infinity 5760a 6ch amp at 56x4 with the infinity 6010cs and 4022i sound perfect

best speakers ever best sound and bass using a memphis 50/4 4 channel amp. tried everything else, even boston auctic, only thing better is mb quarts but they have to be professional installed.

Excellent price. Excellent bass and mid-range for the money. The highs need a little reigning in, but that what an EQ and the ATT switch are for. They have outlived a HiFonics ZXi amp and remain perfectly clear AND LOUD. I will be purchasing a pair of the Kappas soon, just to see how much better it gets. Oh yeah, by the way, I am an Infinity fan... for life.

Ive owned infinity speakers a number of times I keep going back to them cant beat them excelent sound push them and it gets even better I ran a raw 1000 watts amp with quads and they worked as expected great speakers to me they out performed jbl, dual and kenwood

Installed rear deck Honda Accord and these speakers kick. Have stock radio and Kicker amp. Great buy

These speakers reproduce sound flawlessly. Even at low volumes, their clairity is stunning. There might be better, but with no amp and a good head unit, this is as good as it gets.

i have used infinity for yrs in every car i owned... I now have 3 way reference in rear and 2way reference in doors with head unit...sounds excellent..w i am bout to add amps and eq and new head unit..t for loudness...strictly clarity

I just recently bought 2 pairs and when in my new challenger and I have to say hook them up to an infinity 4 channel and and a mono infinity amp with 2-10 subs and you'll get an amazing sound, they are truly hitting on the highs and I dont care for bass because that's why you need to get some subs and an amp. The sound is amazing I turn it up to about 20 on my radio and it gets to 40 because at 20 it's already very loud.
