I'm very anxious about hearing my audio system (not yet installed). I want to get a basic idea of what its possibly going to sound like. Opinions are welcome. Heres what I have yet to install
Mcintosh 4000 m (6channel amp, 4x100 and 2x300)
2 IDMAX 10's (d2v3 series)
Alpine tv/brain unit (model 1005)
Alpine processing unit/EQ
Alpine 12 disc changer
Dynaudio Mids-front stage (6.5" and 4" each door)
Polk components-rear (5" and 1.5"tweeter)
I know with the proper tuning of course--but I'd like an idea of what kind of bass/sound quality I'm looking at...this is for my 85 vette.
OH--Custom box (sealed)

 

very interested in where you are going to mount that amp...the inside of the C4 is not very wide and that amp is a monster...as for how it should sound... what are you using as tweets up front? I would ditch rear fill all together and focus only on the front stage as the car is so small inside that rear fill is not really needed

 

I don't have tweets up front, these are the same mids/ tweeters that were originally in the car when I bought it, and they sounded AWESOME just where they are......I basically just got a differ amp/subs/enclosure. As for the amp---It JUST BARELY slides all the way in the rear against that back wall at an angle (I will cut some wood to cover over the edges of the amp to look like a custom flush wall in black vinyl--with the 2 meters shown, the box is in black vinyl along with the kick panels, with the fiberglass sub enclosure pulled right up behind the front seats--ANOTHER question--Should I leave the subs pointed towards the seats or away towards the rear? And another question--If I did do away with the rear speakers (polk components)--where could I possibly put those? I do have the 88-89 door sills (black) with some kind of speaker panels mounted inside them--would my setup sound terrible if I were to mount those polks inside those door sill baffles--along with the dynaudios mounted in custom kick panels just above on the doors--I figured some tunes coming from behind would balance out the sound....Now I really need some advice on what to do...

 

John-
Not to toot my own horn, but as you know, I have the same amp and can say without a doubt, performance-wise, you'll never be disappointed with it. It's the closest you ever come to "straight wire with gain." I recommend you talk to bogus here on the forum. One, he is very knowledgeable in among other things, car audio in general, and also car audio as it relates to the C4 specifically. Secondarily, he has heard my system and can attest to it.

So to my point, here's what I'd recommend. Like deiaggie mentioned above, I'd ditch any efforts spent on rear-fill and focus on your front soundstage and imaging up front. With the MC4000M, you have six channels of amplification, 2 for subs, and four for whatever you like. Those fours (channels 1-4 on your amp) I would "spend" for your front satellites (door speakers). In my system, I am using channels 1 and 2 for my mid/tweeters (1" soft dome/ 3" soft dome, respectively); and channels 3 and 4 for my mid-bass (6.5" woofer) drivers, all of which are in my doors. The Big Mac allows for bridging of channels 1-4 which allows for 2 to 4 channles of amplification; I'd use those for whatever you're using up front, then channels 5 and 6 for the subs. Real simple really: front speakers (channels 1-4) and rear subs (channels 5-6).

hmmm, right now, I have for the fronts the dynaudios, each door has 2 speakers running on a crossover--so two speakers wil account for 1 of 4 channels off the amp, so total I'm using only 2 channels off the amp--bringing a total of 4 speakers using 2 crossovers. And its the same for the rear too, 2 speakers in each 6x9 spot running off a crossover then to 1 channel off amp...so that is a total of 8 differ speakers/4 crossovers and all running off 4 channels on that amp. Does this sound ok? Also--are subs best pointed to the back or front?

 

i think you are making it way too complicated add all these extra speakers...what model dynaudio speakers are mounted in the from? with no tweeters you are making those 4" speakers play high freq that they are not designed to do and they could sound really harsh, or they are properly crossed over and just missing the tweeter as it is odd that you have dynaudio mids but no tweeters

as for the amp, it is 34" long, the widest you can go is 32" to make it flat against the back wall and that is really pushing it, IMO, i would sell that amp because it is really too big to mount in your car and look decent with out it taking up way too much space...I would go with multiple smaller amps that can get you the same power but you will be able to mount them in a way that does not look too bad or take up alot of space, unless you dont mind taking up the entire rear hatch...that amp is nice, but its size is really a drawback...here is a pic of my install...I have 4 amps mounted in the car very cleanly taking up as little space as possible

 

my Monitor 1 amps fit that description totally, no xovers, no processing, ony a gain control and raw power

 

here is a link to what I have--except the original crossovers and the small tweets. http://cgi.ebay.com/ws/eBayISAPI.dll...745255935&rd=1
Who ever installed this system, must have sold the tweeters and the crossovers, but replaced with kicker xovers....and the only tweeters in the car are in the rear--Polk brand...As for the amp--I did have it in place and it looks great.....fits just snugly against the back wall, I couldn't make it go flush with the wall of course, but its probably at a 60 degree angle. I got the amp mainly for the power for the subs, these are pretty harsh subs and I would only use mcintosh for now on after using the 443m, so your saying I won't need the crossovers for all 8 speakers--I'm a little confused, because this is the setup the installer left in the car when it was owned by another guy,

 

are you positive the speakers are dynaudio? have you actually taken them out and looked at them? Those crossovers and tweeters are not cheap and would be best with that system as the kicker one might work but it is not designed for it...I would make sure you actually have the dyns first and then buy new tweeters and xovers and have that system the way it should be

as for the subs, where did you hear that those subs are harsh? harsh is generally not a term used to describe subwoofers, more so for midranges in the upper freq range as well as tweeters, so I am wondering why you say they are harsh sounding...that amp will not change the way the subs sound either, a good amp would not color the sound at all...box design and placement are what changes the sound of the subs...

 

what I meant by harsh was I've heard alot of good things about idmax on this forum and the caraudio forum. And yes I'm certain these speakers are dynaudio, I have the speakers in my room and the underside is pretty clear of that. Yeah, dynaudio's are Not cheap at all...I'm pricing them on ebay..

 

i would sell the rear polk components and kicker xovers and buy the correct xovers for you speakers as well as the tweeters...you might think it sounds great now but with all the proper stuff you it should sound a lot better...once you do that, run the 4 channels bridged to the dyns...they love the power

 

your serious, I can use only 1 set of components in the car and it will sound great? Any idea where I should mount the tweets, I have the 6.5 and the 4 right now about to be installed in fiberglass kickpanels on each door pointing towards each seat. I didn't even think of only using 1 set, guess I thought too much power would harm those components.......

 

you will be fine with only one set of componennts...the dyns can take a lot of power, if you find that you are over powering them, then turn the gain down on the amplifier to limit the power

 

Damn straight only use one set of hi-end componets for the best sound quality. It appears you are more into sound quality than to blast your neighbor's windows out. You are heading down the best road right now, woofer, mid and tweet in the kick panel will get you great imaging and stage. Most just use the mid and tweet in the kicks because of the limited space. You must have an automatic transmission.
With proper crossover points and your control of excess volume, wattage should not be a problem
