Dear LBM,

Looks like you will have to decide which amp to buy.

Btw where are the pics of Hu after installation ?

Now which option should I go for...

IMHO, your option 3 seems the best to me... though i would like to ask in what way would your front stage have zero crosstalk?

Thank god some serious answer....thanks Phaji...

Since there will be a amp for the left side and one for the right side....It will have zero crosstalk at the amp level...but the PXA will be giving the signals......

LBM, how will you attain zero crosstalk in between left and right channel?

Its absolutely impossible to attain zero crosstalk just by using individual amplifiers for each channel.

Until and unless you use two individual HU / Processors / Amplifiers for each left and right channel you cannot attain zero crosstalk. But that is being stupid because you will need two copies of CD's at the same time to play in each HU and on top of that matching the playback of CD's in the two HU's will be fun .

Crosstalk can be reduced by using good quality (expensive) HU's with balanced outputs, balanced interconnects and amplifiers with pure dual mono design and balanced inputs.

Sonically, crosstalk does not matter that much in car audio environment because you are never sitting in sweet spot. You are either close to left channel or right channel with reflective surfaces all around offering very less decay for drivers. So crosstalk or no crosstalk it does not make noticeable difference to sound

Practically you will hear the traffic, road, tyre, ambient noise much more in the car than crosstalk .

I am saying that it will be only at the amp end only.....I am not saying it will be at whole level.....who said that....

Thats what I am saying that you cannot attain "zero" crosstalk by doing that until and unless you do it on the whole chain.

There is no point seperating the amplification circuits if your signal is orginating from a single chassis / common board equipment. Crosstalk can occur anywhere in DAC's, Preamps, Amps.

the zero cross talk at the amp level is a benefit which I am getting if I am going for the two separate amps..but to achieve the best a lots of money is involved...like you suggested every thing in two....

in a car envrioment a bit of cross talk may actually be good. It might help center the image sort of like a pseudo center...there are many instances when cross talk can be useful or atleast not harmful.

that said LBM Option 3 does make the most sense not for the reduced croass talk but sonically I have found (atleast in the home audio domian) it is nicer to wire speakers up this way.

Man! I thought having 2 ID Max 12"s in ported boxes were the limit. WOAH! What do I see now!

Option 3 means another 4.01 and a whole lot of rewiring etc... Where are you going to put the new amp? And You're going to feed your midbasses with bridged 290W?
Hey, how much is a ticket to FREEdaBAD?

LBM did you realise that with the optoin you have chosen there will be "cross talk" between the tweeter and the midrange. Not that this is bad but just FYI.
