so heres the history
i managed to get myself a xenon x200.4 amp - this was placed into my system as follows - two channels running my MB Quart QSD 216 component set and then the other two channels bridged to run my JBL 1502D subwoofer ..... now ive managed to score a second x200.4 and also an EQ230 - and i want to add these to my syustem
so heres the possible configuration
we know that the EQ230 has a line driver which i want to make full use of - so from the head unit ive got a set of interconnects going to the EQ - then from the EQ i want to use a single set of interconnects to the first amp - then from the first amp - since its only one set of interconnects ill have to use the 2ch-4ch input - and then use one set of interconnects from this amp using the aux output to link to the second amp and also use the 2ch-4ch inputs button
the first amp will run two channels bridged to actually run the subwoofer - and then the other two channels will power the tweeter form the passives in bi-amp mode for my component set - and since everyone says that the quarts love power i want to run the other amp bridged into two channels to run the mid drivers in biamp configuration
so heres the questions
1) i know that the line driver will increase the voltage that goes into the first amp - but will that transfer over to the second amp if im going to use the aux output to daisy chain the amps
2) the equaliser will also definitely affect the first amp in terms of frequency response - so does that aux output give of the equalised signal - or would it revert to trying to give a flat signal - logic tells me that it should be affected by EQ adjustments - but i just want to confirm this
im avoiding going full active cos i cannot think of a way to use the line driver on the EQ without adding stuff inbetween the EQ and the amps - and i would like to avoid having two sets of line drivers and/or EQ's to run the setup how im intending
hopefully also the amount of power that im feeding the speakers wont kill them since that would definitely be a boatload but since people claim that the quarts love the extra power im willing to take a risk on that just to gain a bit more extra configurability and control - or would i just be better off running things how i have it now ie with a single amp just running a stereo pair of channels for the front stage and then the other two channels bridged to power the sub and just add only the EQ into the loop (keeping the second amp as a spare in case the first one dies)
some xenon questions
If I read that right, you'll be giving those QSD mids 400 watts???? 
I wouldn't give those 6 1/2s more then 200 watts. 400 on the mids alone will equal certen death.
In my research, for every order a passive xover is, it's a 5% loss in power. The QSDs will take 300 wrms and I wouldn't go over that. I can't remember what slope Quart uses but at 12 dB/oct at 300 watts, that's only 270 watts between the speakers, at 24 dB/oct at 300 watts, that's only 240 watts between them. So either way you look at it, you can see 400 watts to the mids alone is???>>>??...

well yeah - ive been reading up on other forums - and many people claim that the QSD's are unnaturally power hungry - there are guys who claim of powering those speakers with a 1000 watts RMS per side - many people feed those mids with amps rated at 600 watts RMS per side - so i was hoping that his would be kind of conservative - if i do use only one amp for the front stage ie 200 watts per channel for the tweets and ditto for the mids then i have only one sub and dont have anything to do with the other two channels - unless i get rid of the sub and get a pair of subs that fit into saller enclosures and make two fit into the space of my current 15" sub and feed the subs 400 watts apiece
so does anyone else consider that one amp running just the 6,5" mid drivers on the front stage would be total overkill
the other option is to actually run the one x200.4 for the front stage and get another amp like an x200.2 (bridged) to run just the sub - but this means spending more money and right now id like to avoid that if i can (only problem with this is then id also have to change the cosmetics of my install plan cos id no longer have two synmetrical amplifiers
so im still unsure of how to go about configuring this with what i have - i dont want to leave any amp channels unused if i do land up using both x200.4's - so should i just stick to the one then and not risk the speakers - cos right now the speakers are the most expensive things ive got - they cost around twice more than both those amps combined
okay - found a link to one of the many threads - not sure if this is allowed here cos its not about PG ......but anyways

all the guys seem to be saying you can feed lots of power to those speakers - and they all seem to be doing so - so im following their example

Welcome dude
They should be fine as long as you are very careful with the gains, clean power will not break speakers.
Unlike the EQ215 , the EQ230 does not have dual outputs, but whatever the one amps sees the other will as well, daisy chaining will be perfect for your set up .
Try not to go too low on the X-overs on the front too , else you will bottom the speakers out. as I explain in another thread , to get fullpower would mean either a tone being played, with normal music you will not have a continuous 200rms.
but variations of power depending what impedence the amp sees at specific frequencies, onething for sure, DO NOT GO FULLY ACTIVE, use the passives on the Quarts , specially for the tweeters.

HI shaheen - had to take the plunge and join up here - with your influence i may just become a collector too 
- and instead of buying stuff to put into the car i will land up buying great amps to store under the mattress like all the guys here 
about the going active - well i cant seem to figure out a way to do it and preserve the line driver cos if i add the active crossover after the EQ then i lose the 8v from the EQ - and im not 100% certain id be able to find a crossover that accepts the voltage - so yes the passive crossover is part of the chain that i cannot get rid off also the impedance of the tweeter is 6 ohm so i couldnt try the other option of trying another brand of tweeter to combat the natural treble happiness of the tweeter via the passives since i will than affect the crossover point
one other quick question - i will be feeding lots of power cable to the amps ie i will use both sides of the power/ground inputs with the relevant fuses - so would i need another battery added in somehow with a relay or with an isolater - or would i be okay if i the factory battery with an optima yellow top and do the "big three" - im concerned since im going to be using two of these amps and thats going to create one hell of a current draw - would i need to upgrade my factory alternator as well ..... the main reason why im stressing over this is because the car is still newish ie it is under a year old and the factory warranty still applies - so to do all these things will affect the warranty and i would hate it if the turbo blows and i dont have a warranty to have it repaired just cos i changed the battery or alternator
again sorry for all the n00b questions - just want to confirm that im heading in the right direction with the system

Hey dude, yeah it will be great to have another collector, there are loads of us here. There is someone in Durban who is selling his entire PG install if you wanna start,
M100 , M25, Basscube and EQ215 oh and 2 x 12in X-Max woofers.
As for the power, I would suggest you use the single input on the amp that will be running the mids , the power draw on the amps is only great when producung low frequencies.
The Big 3 will make a huge difference on your car. and the current draw is not going to be very excessive, they are power happy amps , but again depends on what you are driving.
I have 4 amps in my system with all the electrics and have not upgraded alternator.
Also you are driving 1 woofer, and a set of splits effectivly.
Single 2 gauge from the front and 3 inputs should be cool. Oh and the Yellow top is a must. Best battery I ever used, left my car in sa for 6 months without starting and the yellow top started her right up the first time.

I'm just telling you strait from the horses mouth that they don't need 400wrms nor will they like it to well. If you're smart w/them giving them that power then yea, you should probably be OK.
But I used to be on the MB Quart forum page a few years ago before it was shut down and there was a guy there named Jeff Smith (very well known in the Car audio world) at he has stated many times that they do love power, but 250-300 wrms max is all he would ever consider giving them (IIRC). I've talked w/him many times about going active as I used to have a set of Quarts too.

thanks for the input - but my main problem is that if i feed them only 200 watts of power i dont have anything to do with the other 200 watts from the amp
then the options become as follows - i would need to run the one amp bi-amped into the speakers - feeding the tweeters 200 watts apiece - and then the mid drivers 200 watts apiece - and then get a separate monoblock for the sub - or maybe feed the mids 200 watts apiece and then feed the sub 400 watts on the bridge - and get a separate smaller amp for the tweeters but then this becomes an install nightmare cos i then have to change my system design - no problem since i really havent started the work yet
so does anyone else have any ideas

well thats actually the idea - low gain coupled with not playing them very loud or stressfully is the main idea - the main thing is that even though its 400 watts i dont need to be using 400 watts all the timeIf you're smart w/them giving them that power then yea, you should probably be OK.
remember too it wont be fully active since i will be bi-amping through the passives - and the reason why im glad im looking at using this setup now is that a lot of you guys have used it in the past and can help out with it now - so thanks very much for the inputI've talked w/him many times about going active as I used to have a set of Quarts too.
okay - with my experimenting ive managed to come up with this so far - ive actually bi-amped the component set and it does give a lot more control - but i havent tried it in conjunction with the sub - ive still only used the one single amplifier thats plugged into the car - but IMHO it doesnt give me too much more benefit other than a slight bit more control over hte speakers which may benefit the speakers if i dont use the EQ
but the EQ is on its way - so i will have plenty more control over the speakers with the EQ so i think i will be actually causing a bit of strain on my cars electrical system by having two of those amps there ( i havent changed the alternator or battery yet
so im thinking maybe i should just add the EQ in and keep that second amp as a spare in case anything happens to the first one - if i do want to bi-amp - i just use another smaller amp on the tweeters ie maybe just to keep a similar sonic signature i just get myself a xenon x100.2 for the tweeters which i think will actually do very well as a tweeter amp with the x200.4 actually running the mids and the sub
i reckon that will suit my car a bit better and maybe solve the problem of too much power to the mids but allow me the flexibility im after even though the EQ should take care of that
