Car Audio Advice from the Audio Gurus: Use "Search thread" before posting a new Q!

Does anyone have experience in using "Eclipse" headunits (Made by Fujitsu). This query is for a friend who owns a car audio store and wanted to know if these headunits are good to stock? I saw a manual at his shop when I was there last time and they looked good dunno how they sound.

Not a bad idea, unless the combined impedance causes problems to the HU.

But, even the 4" drivers sound quite nice in a Santro loaded on the HU. Did you try to match the levels of the amp and HU? If done properly, you might get good sound from the current setup without changing anything.

Are these the ones by Fujitsu Ten? They get good reviews in Japan, Germany other countries, but none of the car manufacturers has got them into India.
How are the prices like? That's normally the killer.

going by this phenomenon I think what Der Alte said might be more correct. It just might have been that I switched cell phones soon after I sheilded the RCA wires (I dont know it was a ong time ago around 1996 or 97). Der Alte's explanation looks better researched but this does not have a solution.

and in this case your dad cellphone might be radiating more power than yours.

Finally i will go for door mods, if nothing els could be done..

The mods need not be as bad you think. If you dont mind loosing the OEM look then a spacer ring and some cutting might be all you need.

You could use the dash location for the tweeter but the other option (which requires 4 channels of amp power) is to get a pair of 6" woofers in the door and a 4" coax in the dash pod.

then you need a 4ch. amp that has HPF and LPF at say 200Hz. Let the 6" run LPF at 200hz and the 4" run HPF at 200Hz. with a good coax (Alpine, Infinity, Hertz Energy, Blau Velocity) you can get decent sound. The more traditional approach would be to leave the door pods unfilled and install the tweeter and woofer on the door as per LBM's pics.

But as the OLD MAN says why not tinker a bit with the fader setting and see if that helps.

I have heard these and they are quite nice. They are also well repsected by the rest of the fraternity (see other car audio forums).

guess its a fault with cables ? going again tomorrow to get it redone

just an update , the installer added a choke to one of the power lines from the head unit and problem seems to have gone ..

Navin any particular model numbers if you remember? Like for Alpines the 9830, 9833 and 9835 are the best.

whats a choke ?

Sam Kapasi · 27th June 2007, 14:00

A choke is essentially an inductor, a coil.
The DC resistance is low, AC resistance is high. That's as simple as I can get.
It is used in series with DC voltage, thereby reducing the unwanted AC content in the DC current.
A choke in series, in conjunction with a capacitor in parallel, will help in cleaning out the dirty AC content from pure DC. This is one of it's many uses.

Can you post a pic of what was put in? Will be great since anyone with the same problem will know what to do - and bless you!

Of the top omf my head there was the 8xxx series and the Eclipse 5000. Then again I am not good with models and prices.

Hahahaha god one sir and the correct way to explain my setup. so when are you coming to delhi for having the laddu from inside and the outside both.

Speaking of inductors, suppose instead of giving the wire straight to AMP(12V DC) I rotate it around a wooden stick 1" thick giving tight curls(20-30 curls).
This should remove high frequency noise(which I suppose most common car alternators have).
I will do this away from the amp and speakers so that the electromagnet formed does not foul up things.
