for the rear fills i have a 3way infinity ref 6*9 and a pioneer sub at the back. i'm using a 4 ch amp to drive them.

couple of weeks back a friend of mine iced up his i10 with pioneer HU and polk db6501. NO amp. I liked the sound of it. i would like to have a similar component speaker setup on my santro. plan is to drive these components with my existing 4 ch amp and give my sub a rest.

hence the Q, can 6.5" components be fitted on santro doors.

Hey, there are 4" Components avialble from Illusion audio and JBL - could try them

I think, you will be much better off buying a genuine MP3 player and then connecting it via the aux in your car's head unit.

your plan of playing a PMP / iPod through the Aux-in is good - that's how most people do it. I assume that your HU has Aux-in brought out. The connection from the PMP / iPod is from the headphone socket.

thanks bj96 and deralte for your inputs. i will buy a mp3player/ipod.

gurus, Can 6.5" component speakers be fixed on santro doors ? santro does not have factory provided provisions for speaker fitments on doors like i10. How much of modifications would this involve ? thanks

I am no audio guru but would definitely recomemnd 6.5" over 4" - you will need to cut open a portion of your door panel to accommodate the speaker on a MDF spacer(check the ICE forum and you will find pics of Santro installs.This needs to be done carefully

I personally don't like the stock location of 4" in Santro - the stock location in Spark,Wagon-R,Alto,Versa is v.good(near bottom edges of windscreen)

How can I improve the audio on this ancient setup?

Ok, so got a pair of JBL GT5-S204 (4") from Reliance Autozone last Sunday and installed them myself in place of old speakers in the dashboard (I have pictures of DIY, which I will post separately). Felt the instant improvement in the audio and we enjoyed our Sunday family ride. Tape played very well and most FM channels also sounded good, except, a couple of them which gave some hissing noise- probably due to reflected signals as I stay behind hills.

Anyways, while returning from the office today, I suddenly felt that most FM stations were not sounding as good as yesterday. Switched to tape. Same result. Looks like some mid/low is missing and frequency is (unusual) shrill/high pitched. Few songs off tape, still sounds OK though.

Could it be because of reversed polarity in speaker connection?

I just replaced the old speakers with JBLs thinking earlier install (some nondescript speakers) was professionally done and must have the right polarities. Also noticed that earlier installer did a shoddy job as he has cut the OEM harness and there is no way I can identify the right polarities off the HU unless I dismantle and take out the unit from the dash trace the wires.

How can I figure out the right polarity w/o taking off the HU?

I have the bill and warranty, but, don't suspect the new JBLs yet.

Pls help please:.

Hi,

My current setup is

HU : paioneer 4150
front Speaker 6' JBL Component.
rear speakers jbl 6 X 9 GTO 300 watts.

Want to add 4 channel amplifier and also want to replace current rear speakers.

which is the best ampli under 10k and beast rear speakers,i don't want to fit the sub woofer as it eats lots of space from the boot.

@bj96: There is nothing wrong with the JBLs, nor did something happen all of a sudden. Reversed polarity (specifically when ONE of the speakers is wired out of phase) will lead to - at most - cancellation of bass. The 4"ers you have don't push out enough bass anyhow. Also, if you found the reproduction good during the Sunday family drive, the polarity wouldn't have all of a sudden changed on Monday morning!

The difference between your Sunday drive and Monday afternoon feeling might have been absence of external noise and general euphoric feeling on Sunday. The JBL 4" *is* a bit bright, so you were not wrong in feeling "(unusual) shrill/high pitched".

You could try reducing the Treble setting in your HU (even to -ive) till the feeling of shrillness goes away. Another way is to add a layer of cloth below the grill to diffract / suppress the high frequencies.

@parimal_ji, try a JBL A644 / Blaupunkt GT4 Mark2 / Kenwood 8404. Don't replace the GTO 6x9s yet - listen to them through the amp before trying other 6x9s.

You already have rear speakers (the JBL 6x9). Thre are a few amplifiers from Kenwood, Pioneer, JBL and Blaupunkt that can suit your purpose.

Guys,

I have damaged by W7 Jl audio sub 12", please see the pic put here, can anyone advice if this can be fixed, if yes then how and where, also will this affect my performance :Frustrati. I live in Mumbai, will prefer someone in the suburbs or can I fix it myself with a glue, I have seen something similar on the net an reply from Jl audio tech help desk he mentioned about something called GOOP, i guess is available in north america.

Thanks

Thanks so much DerAlte. Your words boosted my sagging morale after this maiden DIY attempt on the audio setup. I adjusted the audio settings on HU and swapped the polarity of the left speaker. I think, it is sounding even better now :).

I will try the cloth trick you mentioned. Is it that cloth would be sandwiched between grill (WagonR OEM Dash grill) and the speaker?
