The RE is a good driver, no doubt, but I think they're a litle overpriced...
The Alpines are going to give you good overall performance, especially in a sealed box.
The MBQuart (no "z") would be my choice, I think, given the three, but NOT by a huge margin. All good drivers to choose from in this group, and all very capable performers.
It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Awesome, thanks for all the great feedback. Now I am torn between the RE and the MBQuarts.2 12's sealed box - Page 2 -- posted image.
Another question: Would I benefit more, in a total sound quality aspect, if I purchased a set of nice components or even possibly a new HU for the front instead of new subs?
My current setup: 1973 Plymouth Duster
(1) Cheapie Blaupunkt HU that I got for Christmas a couple years back        which does the job since 95% of my music comes off my MP3 player
(2) 4" Alpine type s coaxial speakers in a custom box on my tranny hump with the HU.
(2) 6x9 Infinty Reference 9622i in the rear shelf
(1) 100x2 amp which runs the 6x9's at 2 ohm and the 4's at 8 ohms so they are around RMS
(1) Hifonics 1606d running 2 visonik 10w6v2(or some model number like that) at 1.5 ohms almost ready to explode(good thing they are 10 bucks right?) in a ported custom slot box tuned to 35 hz
My only dilemma is that I would like to my best ability keep the car as stock as possible thus cutting into the door panels for a set of components is a absolute last resort, and thus giving me no spot for a set of components unless I stick them in my tranny hump box where they fire into my leg and at the door. 2 12's sealed box - Page 2 -- posted image.

After that last wall of text I figured I would go take a few pictures to make sure the above made sense. Pictures are always fun to look at too.

I guess what I am really looking for in my system is that kick drum and overall just loud and good sounding! Lemme know what you think.
Thanks,

My transmission line and 12W6 kills those quick kick drum hits.
Nice enclosure by the way...did you build that??
Also your trunk is HUGACIOUS!!
How many dead bodies can you fit in there??

Haha, yeah the enclosure was built by me and my brother. Its tuned to 35hz and about 1.5 cubes. I think I could probably fit about 3 full sized people in the trunk and still have space 2 12's sealed box - Page 2 -- posted image..
I have been reading a little about transmission line boxes, but the math is still a bit confusing as I am still learning about ported boxes and such. What is the specs on you box for your 12w6?
Thanks,
~Steve

Well the line is tuned around 32hz unstuffed. Line is non-tapered. External box specs are 38" wide, 16.5" tall, and 21.75" deep
I have been reading up on how stuffing affects the line though so I am going to rebuild another line that is about half as small

This is sort of relative - I'd put componets in the doors - I can't say I really understand why this is a last resort - I can't imagine how using a "hump box" like that would really sound.  I'd cry if I had to use one. 

I mean what are your goals?  "Total sound quality" would make me say new front speakers first. 

With an old car like that, you could dynamat it maybe.  That'd be a cheap, drastic improvement.

I'd think the car needs alot of other things besides new subs - although that is usually the most *fun* upgrade.

I'm glad you liked that. I take it you haven't had the pleasure of talkin to someone born and bred South Carolina.

Hello , long time reader , first time responder to the 12v. I love your car. I had a 74 dodge Satelite Seabring about the same color as yours . I had a similar trunk sub and after installing it the first thing I had to do was DYNOMAT !!!!!  Lots of it through out the car. I also had a very similar consol as yours HU only with some pioneer 3-ways flanking each side. I too did not want to cut the door panels so I constructed some kick panels that could be easily removed and return to stock when I sold the car. In all I had pretty good imaging and seperation but the sound stage was quite low at my feet. I like what youve done but I would definately recomend Dynomat the doors and anywhere else you can .....cieling , floor , rear deck , ect.ect.

For the custom kick panels did you custom fiberglass some? Did they have any pitch/angle to them? I am really reading into fiberglassing here on the forums, but am a little hesitant just to my lack of experience with any such thing. I think I will rammat the doors since that has been suggested twice now.
Thanks for the compliments on the car and thanks for the advice. Much appreciated.
