I know, just make sure the crossovers are of a higher quality.

I was looking into these as well.

The MM6501's Has higher sensitivity/efficiency than the type R's (94db vs 87db).
The Polk's also have 125 RMS compared to Alpine's 110 but i don't understand why it's peak is 250... lower than Alpine's 330.

Also, will these drop right in?

I have the MM6501"s in my S and I think they sound great. They require a good amount of break-in though. When you first listen to them, you may think that they don't sound very good, but they really open up tremendously after the break-in period. The stock basket must be removed upon installation. The brackets supplied by Polk will work fine in the stock position. I paired mine with an MM series 12" sub and in my opinion it sounds wonderful.

yeah, I noticed the peak power goes to the Type Rs

I'm looking for speakers that have a better low frequency response since i wont be running a sub

I think I'm leaning towards the MM6501's though

how is the bass on the MM6501's? What amp are you using with it and how much power are you feeding them?

MEGURO<->2006

I currently have a very small Sony XM-4S powering them. They sound great and the bass response in my opnion is good as well. I originally went with this amp because I was looking to save weight and it fit the bill perfectly. I think they would sound even better with a more powerful amp. The speakers themselves are very light, but very well made. I cannot stress enough that they require a break in period though. Right after I installed them my first impresion was that they sound like the db series they replaced, but after a few weeks all I can say is that it is night and day. I don't think anyone should be expecting thundering bass from their components. These speakers provide a very nice clean sound, play loud and are 500 X better the stock system. The bass response is excellent and I really think you will like them, just don't judge them until after the break-in because there is a huge difference.

How is this set up working out for you?

Is the JL mounted in the trunk? I am looking into that same amp. Where did you mount it?

I have the Polk MM6501s. They will not fit in the stock baskets even if you cut out the back. You'll need to make MDF brackets. I think these speakers sound amazing, even though I'm driving them with the stock '08 HU right now. Some may find them a little bright/harsh, but I like that. You can set the tweeters for -3dB on the xover. With such high sensitivity, they get really loud with a surprising bass. I did just get a Kenwood KDC-X994 HU I'll be installing later though. Even with the stock HU, I'm still happy enough with the volume and bass to not want to add a sub, as ultimate sound reproduction is not my number one priority in this car.

That's interesting; out of curiosity, what causes them not to fit? Is it the diameter of the speaker compared to the baskets themselves?
