im looking to upgrade my HU.im looking at either the clarion dxz755mc or the dxz945mp. both are similar in price .the 755 has the mc feature which i like but only a 2 volt preamp output. the 945 has no mc, but has a 4 volt output.if i go with the 755, will i be losing some sound quality with the 2 volt versus the 4 volt in the 945?any suggestions would be greatly appreciated. thank you.

Usually, the higher Voltage output results in a little better sound quality, since the noise resistance is a little greater.

Also, I think that the 755mc only puts out 1.8 volts, and the MC feature is only good for real CDs (sorry, you can't use CD-R discs, only originals).

The 945mp is nice, but I personally found the touch screen a little small and akward in the store.

Now, it seems like you have your mind set on Clarion, but for the same price range, have you seen Alpine's CDA-9855? It's due out in May, and looks quite impressive...Perhaps you should give it a look...

Just curious - how does the deck know which CDs are "real?"

I'm not sure, but I think it has to do with the CD's data material. Or maybe the encoding? Either way, I read its info on Crutchfield.com.

If you had your heart set on that model, and are worried about the RCA Power output, look at its big brother, with 4volts: DXZ955MC

Interesting - I read the same from crutchfield. I'd like someone to either confirm or deny whether that claim is true. I suspect they might be blowing a bit of smoke just so they don't have to support the burned discs later.

If you burn a disc correctly the deck shouldn't be able to tell the difference.

That's not entirely true... For example, in many older CD players, CD-RW's, no matter how they're burned, just wont work...

But to be sure, give Crutchfield a call and see. Or head down to Tweeter, or some other car Audio shop with some Burned CDs (use different types) and try it out for yourself (that is if nobody else can testify on the forums)

well, i've got the clarion 845 with MC, yes it does only have like 1.8V line outputs, but as for recording music, it will record off a burnt cd as long as it's made into an audio cd, (not MP3, WMA, etc) a guy i know had a cd he made that i copied a few songs off of just to try it out, once you figure out how to use it it's nice, the whole deck itself is nice, iam however jumping down to the 745MP  for the 4volt preouts due to competitions this year, i assumed the 845 had them since it is higher then the 745MP....guess i was wrong :P 

but speaking of the 745MP it says 5.1 decoder, does that mean you can adjust the speaker outputs according to where you are in the car like you can with the 945? or is it just if you have a dvd changer and watching a movie that's got the whole 5.1 setup it will reconise it?

Go with an Eclipse with the magic gate memory stick, 8 volt pre outs, SRS ( surround sound), Area shot navigation w/optional GPS unit!!  and way way better than any thing clarion has ever made.   The CD8445 should be in the $500 range, and the CD8455 is going for $599 around here.   If you have an eclipse dealer around you within 1 hour its definately the route to go!

I disagree... I have an Eclipse head unit sitting in my closet. It died on me, and only powers up (no sound output). I paid a decent amount for it too...and it only lasted a year or so... Thumbs down on eclipse for my personal experience.... Look at that ALpine CDA-9855 though...

Besides, I hear a lot of companies are dropping the Eclipse line for quality issues such as this (I think Tweeter is among one of their bigger sellers who dropped Eclipse)

Haha, no I did not steal it. I bought it from Tweeter. And the whole story is I did return it for warranty through tweeter, and they sent me a new one. That one failed too, after two months, so I gave up on the whole deal, and bought an Alpine Receiver...

I agree with Alpine Guy about going with an Eclipse deck instead. Much better quality then Clarion and have excellent features.

Also, it seems to me that Alpine's quality is going down the toilet lately but I may be wrong.

"Also, it seems to me that Alpine's quality is going down the toilet lately but I may be wrong."   

Are you just saying that because they're now selling through Best Buy??? Haha...

In all seriousness, I'm sure he'll be fine with Alpine's upper-end units. Plus, it seems like the Eclipse head unit mentioned ($599?) is much more expensive than the clarion ones mentioned (at $499). The Alpine comes in at $450.

Their head-units seem to still be good but why are the new mono amps for this year half the price of last years models almost??? It seems like thier Type X sub isn't that great either. Somethings got to be wrong if Alpine Guy is now reccomending and using Eclipse in his own system. posted_image

LOL... Good observation suburb, about alpineguy.

But yeah, I would never buy an Alpine amplifier for higher-end systems. There are better companies out there for that. As for the prices, there's some sort of news-release on their site regarding the new 2005 models, using new circuitry and stuff, resulting in lower costs. But I'm sure it's more related to them realizing their Name wont sell amplifiers at that high of a price. I'm sure before you were just paying for ALPINE, not for what was inside...

As for the Type X, I haven't heard it, but from what I've heard, it was a flop too... But again, I wouldn't buy Alpine for its subs, because there are many better companies out there (Although for low-end stuff, their Type R's are AMAZING for the price, But that is a different story)

The alpine head units are still excellent no doubt about that, the look and use are excellent, but since the shop i was working at shut down, i gota move on and i trialed a few eclipse decks and they are to drool over for sq and accuracy , mostly because of the Ei-serv and the 8 volt pre outs. And this year, the features are too hard to pass up.

I was told by a local stereo shop/school that they dropped Eclipse for quality reasons:  They were having too many customers bring in their head unit with little issues, like the face plate not moving to eject a CD, to the HU powering up, but not playing, etc. etc.      It was the shop owner who got annoyed in these cases,  so he reluctantly dropped the line temporarily, until Eclipse gets their Quality Control in order......

Maybe they have by now....  It's been a year since I've stopped by the shop....
But I'm not trying to scare anybody away from Eclipse.  They have amazing sound quality, when the work right,  and nice features (Like ESN).  I'm just throwing  out my own personal experience with the brand, and what I've heard from reputable shops in Boston.

if you guys are shopping @ tweeter your getting ripped off. i bought a pair of boston sl-95 6x9s @woofersetc. for $199. tweeter sold the exact same ones for $299- yeah, ok,but  its free shipping-you do the math. eclipse is out of the question, alpine offers a 1 year warrenty-clarion offers 2 year.

^^^ and what kind of warranty do you think you will receive from Boston if and when those speakers die, my bet is absolutely none. So to save $100.00 on a set of speakers is all great up front but in the end it is most always a double purchase.

Woofersetc.com isn't an authorized dealer for any of their products so they can't offer you the manufactures warranty....

Concerning the Eclipse quality and such...

I have the 8454 model in my car, my 2nd one. The first one had power supply issues, within the first week of having it. I took it back, replaced. The owner had NO trouble dealing with Eclipse on the issues that came up. This new one has had no problems other than the lens foggin because this state is f'ing cold with a lot of moisture. My remote start has since solved that problem.

Though on the I-Eserv thing, that is misleading... Right now it is worthless, it does everything the head unit does in the car. Now given in the future they are planning on expanding it, but for now, that is about worthless. (I called an even asked after I was done what it could do the HU couldn't, nothing.)

Jakesmoke, this is something that most purhasers (especially young males) do not consider. All they look at is the cheapest price and the name. Sure the name can be the same and the product the same but the price different and this is where the "young male" buys his gear from. The other people do a little more research. Most if not all online sites are not authorized dealers for whatever brand of equipment you just purchased from them to save that $100.00. To you $100.00 is a huge savings and the other guys were ripping you off, fact of the matter is you are usually getting burned on the cheaper price.

This is due to the fact that the item may be a refurbished unit and sold as new, it may be a stolen unit, it may be a new unit from a authorized dealer sold through a unauthorized dealer. Lets pick on Eclipse for now as I know their policy on online purchases. You see a cd player advertised in a store for $500.00. A quick search online finds the same one for $380.00. You immediately think to yourself that the stores are scamming you and you tell all of your friends about it and post it all over these forums. (as was done here). So yu buy the unit from the online dealer and then the shipping bill hits you for another chunk of change in some cases. So the unit is working fine for you until all of a sudden one day it won't eject your cd. What do you do. The online store no longer carries the line and sure they can warranty it for you for the one year that they offer vs. the 3 years that the store offers on the same thing. So you send in the cd player to onlinestereooftheweek.com at your expense (more $ out of your pocket) and they can't fix it. Why? because they are not authorized to sell it and Eclipse will not warranty it for them. They will also not go out and spend their money to fix it for you. So they leave you with an option, we can't get that one anymore so how's about this Sony or Driftwood model instead. At this point intime you are pissed as it's been 1 amonth and a half and will take anything so out it comes to you. Is it what you payed for originally, no. Does it do the same things, no. Does it even sound the same, no. Could it be a refurbised item, yes. Could it not be covered by the manufacturers warranty, no.  All to save $120.00 at the outset.

So now you say well if it dies it dies and I can always buy another. Corect you can but when purchasing from the authorized dealer, warranty is never an issue, replacement with a updated version of the same brand is always an option, warrranty length is usually longer and you end up spending less money. With a sub it is even riskier. Look through the forums and see how many people don't recommend this or that brand as the sub bew on them, the forums are full of crap like this. Look a little closer at those who bought online to save a couple of bucks and had to go out and buy a new one as the "warranty" they had from onlinestereooftheweek.com did not cover what happened to the sub. SO you send your sub into the manufacturer (at your cost again) with your sales receipt and it gets sent back unfixed with a note that says "this item was purchased at a unauthorized retailer and we are under no obligation to warrranty it, we recommend you contact your dealer where it was purchsaed". The dealer is no longer in business or can't get the brand any more. Back to the same old issue. What if the box you made was specific to the sub, or the amp you bought had a custom rack made and the amp no longer inproduction, what do you do? You spend even more money again to fix an item that if bought at a manufacturer would have been covered.

When these items you purchased from discounttrailerparktrashaudio.com have issues or problems what do people do with them, they post stuff on the net in forums just like this and ask people like me, legitimate authorized dealers for advice. Once you are burned from an online store you will understand and unfortunately it is only a matter of time. The online stores cater to the "young males" and take full advantage of them and their buying habits. This is business to them and if they have to take advantage of the purchaser to further their goals, so be it. Here today, gone tomorrow - with your money and no warranty. My advice is always buy authorized and say no to Fat Chicks, Sony, Bose and factory audio system.

Im a young male, and I read it!!! If someone takes the time and thought to write something that informative, I figure the least I can do is read it.

So far I bought most of my equipment from a local shop, although i bought my JBL 600.1 from sounddomain, which is one of the more up and up online retailers.

Im buying a new HU soon, and it will most likely be a Eclipse 5425 from my local shop. The three year warranty cant be beat and by now Ive been in and out of the shop enough that I know the guys pretty well, and its always better dealing with someone you know then it is dealing with a big company.

Read it... And I'm a young male... 

But then again, I'm always made fun of for how much I research my purchases (It took me 2 months to pick a cell phone carrier, and 6 months to figure out what kind of laptop I wanted for school). 

I agree with Rob.  If it's too good to be true, it typically is.  I always buy from reputable shops or stores.  The only online store I've purchased from is Crutchfield, and it will probably be the only online store I ever buy from. 

I've looked at stores like Woofers ETC.  and wonder how they even stay in business for more than 2 days.  Perhaps it's the new fancy logo, that shimmers.  Or maybe the USACI logo at the bottom...  People may fall for those gimmicks,  but you must understand that brands like Eclipse, JL Audio and Zapco don't typically support online stores.  And to buy from an online store who doesn't have an 800 number, or who uses woofersetc1@aol.com for their primary email address (and that IS their address) is quite reckless.  Not to mention, it doesn't even show that they have a secure checkout policy...

Pay the extra hundred dollars and buy from somebody who will take care of you!

And remember:

  2 cheap things cost more than 1 good thing.

I have to agree with you Rob, Wayland, and Nick.  I am a "young male".  I am not the typical one though.  I have done my research and am still doing my research.  The only thing i have bought online was an amp from Crutchfield.  I have bought everything else from my local shop.  I have bought a head unit 4 subs and an amp from them.  Plus the local shop will give you the warranty that no other place can actually back up.  There are a few bogus shops out there, you have to watch out for them, plus if they look like they don't know what they are doing, they probably don't.  I totally support my local shop and even though I have payed probably $300 more than I would have online, I have not yet had one thing I have bought break on me(all of my stuff has been out of warrant for at least 2 years).

Support Your Local Shop... It will help in the long run!

thanks for the info rob. i too have purchared most of my equipment with crutchfield, but they dont carry boston acoustics speakers so i went shopping around.i assumed all speakers are made at the same place, like china, tiawan, mexico,-just different vendors. when i saw that woofers offered a one year warrenty, and tweeters didnt say anything about a warrenty- not to mention the price difference-apparently i was mislead. im not a "young male"as you put it ,although im fairly new on all the technical and the vast array of difference in todays car audio. ive been putting in my own stereo systems for twenty some years now but lately have been making it a hobby to learn more about it all.in the "old days'  it was a supertuner, good 6x9s and a small amp and you were good to go.those days are gone with all the selection there is today. i appreciate everyones replies and like i said, im still learning.posted_image thanks again.

Ive never had any problems with eclipse products of anykind. ive had them in my cars for at least 6 years and the only reason i have the newer stuff is just because ive upgraded. the people ive sold my old equipment to havent had any problems from then on either. the radio i have in my car now is going on little over 4 years of trouble free use. the onlything that started to happen was the track select ring rattles a little bit but i can easily fix that. until i get the money for their new 5v 2din nav unit im going to keep my 5441. even after i get the new deck ill have it as a keep sake. lol
