Guys,

Re: Sound of the rear speakers

Its because in your car both the speakers are placed on one side.

Use fader settings in your HU set it to Rear so that you can hear the music from Rear speakers.

Varun, Yes as of now I am managing with Fader settings in HU. For example I will set REAR ones to 8/10. then I can enjoy the both the speakers [rear one has those base effect nicely]

And i presume having speakers together will have effect on stereo not in entire volume. if am wrong pls correct.

Re: Sound of the rear speakers

Sethu Sir, first of all i would like to know why have you placed the rear speakers like that?
The main culprit for your problem is the wrong placement of speakers. BTW looks like you aint an Audiophile, since 250W is too less for the thump.

As Sethu's car is lpg, the spare tire is fitted behind the seat so that the speaker can't be fitted.

Answer as given by Varun

Yes Akash I love music but not a banging one. I don't even have tweeter in my car since it will make my head ache immediately.
For 250W speakers there where two reasons. Actually my friend gave me set of speakers which I can use. He said it is a new unused one. But when I fix that in my car it started giving all kind of nasty noises. Since the speaker was available I could not meet the immediate raise in the budget. If this happen just 30 minutes back I would have stopped reverse camera. But by the time the guy told me about the speakers everything was done. So I had to go for the one whatever my budget allows.

Okie if i ask you what I can go for? if possible to exchange I will go for another one. [I think I should get permission from my wife since she hate SOUND]

Re: Sound of the rear speakers

you can try fixing the rear speakers in a separate enclosure. this may solve the low volume at rear problem.

Re: Sound of the rear speakers

well, in the picture you see the speakers are fixed on a separate box. these speaker box can be kept on the rear parcel tray so that there will not be a problem with the spare wheels. hope you understood
Yes. I understand. I even thought of the same thing. I need to have a good carpenter who can do that. In that case I need to change the entire parcel trey. Or should do the following

reduce the cut from red to yellow with additional wood. and also block the current speaker holes. so that they become flat one.

and do a enclosure like this and fix it.



So i need not to go for a entire change of parcel trey.

Anyone knows anyone in Chennai who can help me?

BTW Sai, how you are saying by adding an enclosure for speaker will solve the sound issue? do you mean to say all are having in separate enclosure? and should there be open beneath the enclosure in parcel trey?

Re: Sound of the rear speakers

Sai there is no noise in the setup. only problem is rear is less volume in normal mode [FAD = 0] So I manage it in FAD = Rear to 8 to 10 somewhere.

please mention your HU brand and model no,
the problem is with the misaligned setup , may be

check for one more thing. keep fader full rear and increase the volume from 0. if you still feel some thing strange your speaker polarities are reversed

I did and nothing wrong in it. changing the polarities will help? why iam asking this is, i can change it easily since i have used plugs [ordinary electrical male-female plugs] for connecting speakers with HU. Will post some pics tomorrow if possible.
