I just installed four Infinity Reference 652i 6.5" ($69/pr at Crutchfield) and they sound great with the stock radio and no additional amps. Very clean and punchy. They don't have rumbling bass but that's what a sub's for anyway. They're 92dB so they're a few clicks softer that the stock speakers but still loud enough.

Had thought about Infinity Kappas but they're not very efficient (90dB) and the factory speakers are quite efficient (guessing 94 to 95dB) so with the stock radio the Kappas are going to be pretty soft and I think rather disappointing.

My next upgrade will likely be the Basslink sub and Infinity tweeters in the A-pillars. I can only imagine the sound then...

Just for the record, the speaker wire colors for an '03 are:

RF+ brown RR+ blue
RF- brown/white stripe RR- pink

LF+ blue/white stripe LR+ light green
LF- blue/yellow stripe LR- black/yellow stripe

 

i've had these for more than a year and they sound much better with any amp at all. these things sound great even with the cheap pioneer two channel i've been using, much, much more powerful.

 

What kind of wiring do you have to do to the max to get these to work? I was told that you have to rewire the entire system???? I want to get the infinity 652.5i's for my and my fiancees car(she has a saturn, and her speakers are blown to ****)

 

rickso03, Do you have the Bose system?

 

dust popped the old ones out, put the new ones in and soldiered the leads in place. if you're gonna use an amp then the procedure is different.

 

so you don't have to run all new wires for aftermarket speakers to an aftermarket headunit? Do you have to remove the amps that the Bose system has?

 

if you ahve a bose system you will almost definately have to rip out the amps as well as the HU. i had a regular system with [now] an aftermarket HU and these 652I's

 

If you run the amps and bose speakers with a aftermarket headunit, you will have about 2-3 volume settings, you can't put much into those amps, there looking for very small amounts of power, with a aftermarket ur already pushing to much into them. Get a new head unit, get new speakers and turn it into a weekend project, just cut the power wires for the bose and cut all the stock connectors, thats the easiest way to do it.

 

good stuff, im planning on getting those, i wanted infiniti's for the longest time, ill be picking up a coupla pairs of those soon....esp for only 69.99 a pair!


And question, with the stock tweeters...did you leave them in? Are they running off the infiniti?! or what?!

I rewired my boss system and they hit and sound great. It is alot cheap than gon out and buyen new speakers

 

What exactly did you do?

 

Would these work in my 97 Max equipped with Bose(Pioneer HU though)?

 

I have been singing the praises of Infinity Reference series coaxials for almost 10 years now. I had them in my 1990 Accord as my first system in 1994. I also bought 4 of them with an aftermarket head unit and they sounded GREAT. In fact, I am still using a pair of them out on my porch as home speakers in little enclosures I made. Back then (not sure about now as I haven't A/B'd then for a few years) they actually sounded BETTER to me than the Kappas.

Good luck with them, you'll keep enjoying them for years

 

I'm running my stock tweeters and i've had no problems with them yet
