    That is not true....having the same brand throughout your car does not make for better sound quality. They are audio components and they can't read. The only thing being transfered through the wires are voltages and signals. In the end, it is the build quality, efficiency, and install of the components that make up your system that count.

    If you're dead set on getting Alpine products...check out the Alpine Type X components...they are very musical speakers and sound great right out of the box. I wouldn't go for alpine's lesser models.

    Or is there some sort of riser to bring the speaker out more so you don't have the modify the door frame? bring it like 1/4" closer to the drivers legs?
    You can't really bring the speaker closer because of the speaker grill and the fact that the circle opening in the door where the speaker grill sits is less than 6.5" in diameter.

    You will have to take measurements of the speaker you want to get and see how much space you have behind the door to work with....i can't remember exactly how much room there is behind there.

    You can definitely do it on your own....there is a diy sticky on the page that i linked you to in my first post. It walks through a speaker install in a 3 series step-by-step and is very detailed with pictures. It shows you how to remove the door panel and where to tap into the wiring, etc.

    I've done it myself many times...the first time took the longest (trying to figure out how to take the door off and how to mount the speaker)...but every time after that was a breeze since i already knew how everything fit together.

    To mount a 6.5" speaker, you will need mdf speaker rings and you will have to bolt them to your door panel. You will then bolt the speakers to that mdf ring and seal around the speaker with dynamat or with a foam insulation so that the airspace in front of the speaker is completely sealed off from the air space behind the speaker.

    Thats interesting, I feel the Type X may be a tad too expensive, so if the lesser models arn't as good I'm still going to check out Rockford Fosgate, as my dads' 2006 Eclipse came with a factory installed one, and it sounds pretty good to me.

    And thank you for the very informative posts on how to fit speakers, you guys did a great job at answering my question. I had a hunch I could get something in there that crutchfield says I can't.

    Thanks a lot.

    ^^^ G'luck with your install and be sure to check forum.e46fanatics.com for any of your 3 series questions.....if you're trying to do something to your bimmer, chances are that someone has already tried it and can walk you through it.

    Ok so I yanked off the door panel, and measured the speaker. The whole thing measures almost 6.5 inches across, but I think the cone is only 5.75". Honestly I dont know a whole lot about car audio, I'm just starting. But I also measured how deep the speakers are, and they measured 2.5".

    I'm thinking about just doing the same set up as my friend did. The Alpine Type-S SPS171A component speakers up front, and I think the Alpine Type-S SPS170A speakers in the rear deck. I'd go for thier higher end speakers, but a Type-X set up at least double what I'm looking to spend, and I'm not going for competition quality sound, just an upgrade over the factory.

    According to crutchfield the SPS171A speakers have the same depth as the speakers I already have.
    http://www.crutchfield.com/S-YV8YX1Z...Display=Alpine
    Will I have to cut into my door metal? and if I do, whats the best way to go about this?

    Another concern is the speakers in the rear deck, I hear they're the same size as the ones up front, but if the new ones don't fit I'm sure it's easier to make them fit since theres theoretically a lot more space to work with than in the door.

    I registered over at the E46 fanatics forum, but my account hasn't been approved yet so I can't use the forum search :/

    If the speakers have the same depth as the stock speakers, than they should fit. The only issue with mounting 6.5" speakers to the stock location is depth clearance. You can actually have the speakers be slightly deeper than the stock speakers as u should have some extra clearance there.

    The rear deck speakers are like the front speakers....6" all the way around (not quite 6.5")...so in order to get 6.5's to fit in the rear, u will have to make slight modifications to the mounting brackets. It is as simple as drilling a new mounting hole and the speaker should fit in there pretty snug.

    My car us currently at a local audio shop and they're installing the 6.5" Type X's in the front doors (i blew one of the mids on my OZ Matrix elites, so i bought the type X's.....200 bucks on ebay). I'll let you know what i think about them as i am going to pick up my car this afternoon.

    While this is true for most of the car audio systems on the road today it does not hold true for all speakers, if you start spending real money on speakers, F1 status stuff, Utopia, Diamond, Rainbow etc. you get into "tamber matching " the speakers where the even minute diferences in potential frequency response can cost you big in a show or compatition. So if you are looking at the everyday alpine stuff (type s and type r, or the rockford punch or power series stuff) id say mix and match all you want however if you decide to really invest the time and money into building a true SQ system then i would find one brand i really liked and stick with it at least as far as speakers go, amps, head units, sig procs etc don't necesarilly have to match but it doesnt hurt.

    /end of rant
    Friends don't let friends install car audio.

    bull**** of sticking to one brand for sq! you are missing the most important thing in SQ, that's soundstage and a clean sound. to accomplish sq you have to look at each component by its self. look at how the tweets sound, how the mids sound, how does the kicks and subs sound? and from there you can mix and match to your own likings but also important, to your car. every car sounds different. The thing is, if you stick with one brand it could be -par example- in my car, the tweets can't catch up with the mids but in my brother's car they do.

    I'll give you an example of how my install is gonna be.

    2 NOVA MDS08 subs
    2 PEERLES C165ip kicks
    2 SEAS 25TFFN/G /NOVA TN25MKII

    If i follow your opinion I should stick with NOVA

    but the peerless kick go a little deeper than the nova equivalent.
    and the seas tweets sound less agressive than the nova's although they are the same (but the nova is slightly modified)

    "tamber matching"
    Someone should revoke your certification It's timbre. Tamber is a type of door usually used on rolltop desks.

    Otherwise, I can't argue with you.

    bull**** of sticking to one brand for sq!
    Dude, he's right. He was mentioning EXTREME high-quality stuff when he said that.

    don't think rainbow, focal utopia's, .... and peerless, seas,... are that different in quality though... they're different in sound though, and I would think sound is pretty important too.

    Or maybe I just don't get your reply correctly
