Speaker info - Which ones

I have been out of the car audio scene for some time and I do not know who is making good stuff and who is making crap these days.  I need some input on speakers, if you are willing to help.

I am in the process of upgrading the system in my 97 Toyota Landcruiser. It presents many "fun" opportunities in and of itself. Seeing that I would prefer to use the factory grilles, I am quite limited. If I decide to go with using the new speaker grilles, I have a little more variety to choose from. I will be putting in a sub, but I am hoping to put something in the space where the current "sub" is. This would limit me to an 8" sub in a custom sealed box. 

WIth this all said, I am trying to determine the best setup for the front doors (6 1/2") and the rear doors (4"). I would like to stick with the same manufacturer for front and rear to better "match" the sound (is this the right approach?). I am also considering coaxial speakers because I want to do the least amount of mods possible. I am up for separates in the front, but need a compelling reason, and need to figure out where to mount the tweeter.

Below are the things I have been looking at. Please give me your input, and any other options you might have. (Keep in mind that for the front, if I keep the factory grilles, mounting depth cannot be more than 2" max, and using the speaker grilles, I might be able to go to 2 1/2 if I squeeze things.)

Infinity Kappa 62.5i (front)

Alpine SPS-170A (front)

Boston Accoustic FX6 (or NX67) (front)

JL Audio TR650 CXi (front)

Kenwood Excelon KFC-XR601 (front)

Eclipse.....

MB Quart......

This have become a longer list than I thought. But the main purpose here it to figure out to make this all happen using the smaller 8" sub from JL Audio.

Any and all comments are GREATLY appreciated!

I would not replace the factory speakers in back (your passengers will be the only ones hearing those) and put the money you would have spent there into the best 6.5" component set you can afford.  You really need to listen to all those speakers to decide.  When I've demoed speakers I've found that Infinity and Boston make top notch products for the price.  I have not been impressed with JL speakers other than subs.  I have no experience with Alpine or Kenwood other than to say that Kenwood doesn't have the best reputation.  Eclipse and Quart make excellent speakers.  You should consider their offerings as well. 

If I had to buy some component speakers fresh right now at the top of my list would be the Adire Audio Koda Component set:  http://www.adireaudio.com/ and either of the 2 sets from Resonant Engineering http://www.respl.com/    (I just noticed their site was down.  You can look at their products here too:  http://www.bladeice.com/ )

Good input.

I was thinking NOT going separates so I could minimize (or eliminate) any permanent mods I might have to make. I know that I give up a little that way, but that is why I was thinking about the Infinity Kappas that have a seperate crossover to help keep things where they are supposed to be.

Any thoughts in the coax world....

That's right. Add more to confuse things!!!!

I do like the way the specs and such on the Memphis speakers look. But I don't know much about them.  I'll do some reading and research on the MB Quarts and Memphis.

Boy, just when I thought I was starting to figure this out!

Thanks.  I found a place locally that is on the Memphis dealer list. Heading there tomorrow at lunch hoping it wasn't a typo........

Wish I could find a place that had both the JL, MB Quart and Memphis....... so I could a/b/c.......

What is the history and such of Memphis?  They are unknown to me. 

I appreciate all your input. It has helped. Even if I am a bit more confused than before!!!

Went and listened to the Memphis, and the dealer had Diamond as well. Good stuff.  Then I went and listened to the MB Quarts. OH NO.  I'm screwed. So much for the easy way. The PCE216 components were absolutely amazing!!!  I think I will have to figure out how to save up for them and then MAKE them fit in the Landcruiser.

Oh, my wife is gonna kill me............
