Guys guys...cmon.....Im surprised at everyone.....

1500W??? cmon...thats kooky talk....youll be lucky to pull 600.

Youre telling me youre gonna max your gains on the audiobahn.. You wont need half of it. You wont be able to hear anything. Youll be sending about 80-110 to the mbs (50W average)

60 to the rears (they will explode with 100+ watts) (15-20 watt average)

and about 300-400 sub, (250 average)

Youll be NOWHERE NEAR 1500.

I repeat, DO NOT OVERPOWER THE MBQUARTS. I have a LOT of experience with QSDs, they dont like it. If you get them legit, MBQUART will not honor warraty if you over power them. Please let someone who knows car audio tune your system.

Anotherthing....I need to make a comment...

Your system is all over the place....

You got 500 top of the line MBQUARTs, only to drown them out with piss quality boss speakers. You are spending all this money on nice sound, yet compromise on a lot of things. I dont want to have to tell you the same thing many of us told natedog, "I TOLD YOU SO"

Rethink this whole thing.

Ditch the second amp.
Ditch the POS rear speakers (PLEASE)
Ditch the audiobahn sub, and put in 2 nice 8" in a WLAURENT

Do quality not quantity...you already learned "measure 3 times, cut once"

Dont learn another lesson, and take it from us who learned them all.

Good luck.

 

I dont know if anyone else noticed this.

Pete you said as follows:

It looks like I will be putting out 1500W.

150W x4 Fronts = 600W **** emphasize here ****
150W x2 Rears = 300W
600W x1 Sub = 600W

Are you bi amping the MB's?

No way in hell, do you want to send 150 to the tweets, you might as well step on them and hit them with a hammer before you install them.

NFR is right, those numbers are peak, when you volume is at its highest, you only spike that high everyonce in a while, it will not be constant.

Toss the boss. In my opinion, in our car you dont need rear speakers, the cabin is so tiny that just the components in the door properly amped will be more than enough.

I cant speak for the Audiobahn Subs, but I would suggest you go with whats been recommended and put to the test here before, no point in putting in something just to replace it. ThaTs the worse feeling, installing something and knowing right away its not right! Happened to me twice.

As always good luck, and keep us posted.

PS that cap looks nice FLith (how you been?)
By the way I am running the SS 500.4, with a ten inch sub getting 500 watts
rms, and my lights never never dim. I am running 125 watts to the Utopia's
in the doors. I dont think there is a need for a cap, if you want to just be on
the safe side, as others have recommended get the Optima battery. I did.

 

Hey Pikkashoe!

I've been saying the same thing above. I agee with Dave 100%. The Audiobahn gear is really bling-only. Don't think that they give you the cut chromed enclosures for free or for sound quality. The rear speakers also can not help sound quality. If you hear those rears at all you are losing quality (the MB Quarts are worlds better). You might as well just turn up the volume on the MB Quarts.

Again, with power I run 125 watts x 2 and 350 watts x 2 to my subs for 950 watts. That is RMS, but that's not what my ears can handle. I doubt I ever hit more than 400 watts total in the S2000 and the stock alternator and battery powers everything with ease without a cap.

 

Somewhere I got the idea that the Peak power on the Quarts is 300W. I checked the Owner's Manual and the MB Quart website and they don't specify RMS or peak, they just lists them at 90-170W. On the website, they list the power range for the same tweeter (QTD25) at 120W. [That's not much of a range.]

I called the electronics company before my payment arrived and made more changes. I got the Audiobahn A1004DP to power the Quarts. It puts out 100W x4 and is the same size and series as the other 2 amps.

I'm not buying the Audiobahn amps for great quality, I'm buying them because they are compact and put out a lot of power. I know the rule with amps is that the better ones are usually bigger and heavier, and I want to keep the spare tire and functional trunkwell.

I would like to get better coaxials for the rear, but I can't find any that will fit and put out a lot of power. I've been trying to avoid putting separates in the rear, but I guess I'll have to give in and go for the MB Quart QSD213 5.25" separates.

I'll power the 4 rears with the Audiobahn A1502DP amp (150Wx2). That's 75W to each speaker, and they are rated at 70-150W.

Another A1502DP amp (600W x1) will power the sub.

Thanks to everyone for the advice. Please keep it coming. As you can see, I'm listening.

Are you running 125 x2 to the QSDs?

Maybe I misunderstood, because you recommended the VGA500.4 (125Wx4).

-Pete

 

the other two channels are for his sub.

 

I see.

I've been trying to get info on the power handling capability of the QSD 216s, and I found this info on the MB Quart Competition Team website:

would the mcintosh mc431 4x100w be enough power to feed these speakers to thier full potential?i would use all 4 channels to run both speakers and tweeters.,,,,,,,,,,,,,,,,,thankyou.

More than true, Byonhd is correct. Scott Buwalda was at one point a officially Sponsered Expert competitor, it was a 1995 Nissan 240SX special edition, the amps (all 6 of them) were the Zapco 9.0(900watts mono rated, tested out around 1100)he had a total of 6 one to each driver, QSD216 set, and a pair of I believe premium 12" subs. Scott has moved on to a Nissan Altima, and now works for DLS. With the proper equipment upstream of the amps (x-overs, etc), these speakers will work with that kind of power.

Right now I've got a '98 Prelude.I've got one pair of QSD 213's in my doors (stock location).I've got them biamped with a JL 300/4. I've also got a JL 500/1 running a 10W7 sub in the trunk.The system sounds great, but I'm already starting to design a new system for the G-35. Biamping is definately the way to go.You can get much greater control biamping.

as for the sound stage, what car is this in? most cars work well with tweeters in the kicks. as for the power, maybe trade the 450/4 in on 2 300/2's. the last system i have done with qsd's and 2 300/2's had 2 1000/1's on a pair of 12w6v2's in an exterra and it RIPPED!!!!!

Yeah, what Brad said. I had a pair of QSD216's in my Ram, I put as much power as I could and put the mids in the doors, and dynamatted them and made wood spacers, then mounted the tweeters in the kicks as far away as I could. they are designed to be installed this way, either that or you have to attenuate the driver tweeter all the way down, or you cant even tell the passenger side is playing. Get lots of power for them, The Q amps should be shipping, thats where to invest, not a second set of speakers.

kevin these speakers are top notch and will handle a QAA4250 any day of the week. Just becareful of the mechanical power limits of the speakers depending om the music you listen to!

Here is the second email I recieved from Dan Hunter, who told me differently in regards to the QSDs biamped to the QAA4250. His title is shown to be the Product Planner for the company, so I would imagine he knows what he is talking about. How much power from an amplifier can the QSD216's handle without blowing up?

You received the following message from: Dano9177
(hunterda@rockfordcorp.com)

This post was brought to my attention by another consumer who actually
already has one the QAA4250's running a set of QSD216's bi-amped. The
information that Tony gave you would be fine for the average consumer.
However if you want to go this route the QSD's will definetly handle
the power. The way Quart speakers are rated for power is in a DIN
standard so when looking at the power handling #'s its not RMS and PEAK it is
a power range the speakers will work in. If you would like to talk to
me more about how to go about setting your system up feel free to call
me at 480-967-3565 or you can email me at dan.hunter@mbquart.com.

It sounds like you are concerned about overdriving these speakers, I just re-installed my QSD's last night into the jetta, I am one of the people running the QAA4250 bi-amped. I was running them this way in my truck for about 3 months before I sold it, and I have had the same set of QSD's hooked up since 2001. Most of that time running a 150x4 setup to them.

I'm more confused than ever about how much power I should run.

I am thinking about changing the amps again!

[QUOTE=NFRs2000NYC,Feb 26 2005, 11:52 AM]Getting rears is a waste of money for you.

 

Pete, that's interesting about the biamping but I can't imagine you gaining anything from doing it even if the speakers can handle it gracefully. I turn my highest highs down 90% from default. They are still exceptionally bright, occasionally painfully so. More power can't help there -- there's no way you can use even a tiny amount of power on the tweeters. I can imagine that on paper that could help numbers, but in reality I don't think it would be possible for it to help enough for you to be able to pick the biamped setup blindfolded. Start your engine with top down and you there's no way recording equipment could tell them apart.
