True. However, even when playing just the rears with the fronts and sub disconnected, the sound was very faint. Maybe a HU problem. But that's already discussed in another thread - would be OT here

Ideally yes.

Pio 4950.
I don't have the components. I have 4 x EL62 coaxes. They cost 3990 each. The 6.1 is around 6.5K.

Not sure. Am not aware of the technicalities around this. But be sure if you wire it that way. However with 6x9 coax rears driven by the HU, you need not go into those complications.

So I guess the Illusion Electra 6.1's up front should be powered by the amp channels 1 & 2. Now the HU should drive the JBL 937 co-axes better than the Illusion co-axes since the 937's have 2 ohms impedance against the electra co-axes which has 4 ohm impedance. So the HU must be able to push more power into the JBL's right??

Will this setup, Illusion 6.1's at the front and JBL 937's at the rear, have any problems like sounding different or something??

Yes and no. The lower impedance and higher power 'push' due to that is not an indicator of louder or better sound. If at all, the 'Sensitivity' figure is - higher the sensitivity, louder the sound watt for watt. Better sound? No, nothing in the data sheet is a general indicator of that - that is why everyone recommends an audition - your own ears are the best judge.

Mix and match is OK - since you never get to hear both the front and the rear at the same time.

I would prefer same brand and same series speakers in front and back.

LBMji I was thinking of such a setup because shuvc said this..

Initially my 75.4 was driving the fronts + sub. Rears were driven by the HU. I had a problem with this. The rears were very faint. Root cause not identified.

B&T suggested I take your option. Which is how it is wired now. Left Front and Rear to Channel 1, Right Front and Rear to Channel 2,
Sub driven by bridged Channel 3 & 4.
This does produce a centre-rear sound stage, which I am ok with.

Now since Illusion co-axes are 4ohm and the JBL co-axes are 2ohms, I guessed that the HU will push more power into the JBL than the Illusion and it will sound a bit louder.

You probably need not worry too much about the loudness aspect of the rears. It is possible to play around with the front and rear 'loudness/volume' by adjusting between the HU volume and the Amp gain for the front compos. In brief, first set HU volume a bit high so that you can hear the rears well and then set the front compo gain on the amp to a low value, so that both sound ok to you.

I have 6.5" round coaxes all around. You could go for Illusion 6x9s oval coaxes in the rear. Power them off HU.

Yes, I think that will be better

I was trying to find out some info about the new JBL GTO 1004 amp but could not find any thread/post about it except the thread where it was announced.

No one got hold of a 1004 yet??
what about Reviews?? cost in grey market??

Can you post the link for that thread here, i'm interested in taking a look

I failed to rectify it so went with the option of powering all speakers from the amp. Maybe I'll someday get a 2-channel amp just for the rears

Check this thread. Prashanth has bought a 1004 amp.

Hey Thanks for the links man. Also Prashanth said he got the 1004 for 9300 in grey. I think it's a good buy because the 75.4 was around 8.5K in grey i think.

I am looking to source the Alpine HU from US since my friend is returning next month. Alpine has a iDA series which plays from USB and Ipod only (no cd/dvd playback) and FM.

I was typically looking at the iDA x300 & iDA x200 from
Alpine Electronics of America, Inc.

How are the performance of these HU's?? I have not seen anyone here in TBHP comment on one. Is it worth to spend around 200$ on these HU's (The rates are a bit lesser in many online stores)?? will be great if someone can throw light on it's price in India so I can decide whether to get it here or source it from there .

Also the iDA300 has only one pre-out as against three pre-outs of the iDA200. Now considering that I will use only a 4-ch amp and no separate mono for the sub(and no future upgrades), is it ok if I go for the iDA300 with only one pre-out??
