Pyle audio is alright, not a bad brand. I definitely think you need to lower your bass mid and treble. Closer to 0 is better.
The Sony amplifier is grainy and the pioneer speaker a bit harsh. Nice to see someone taking such a detailed interest in his equipment. Keep it up.

Sam, thanks for the compliment. Always had an interest in ICE and it's grown even more after T-BHP.

When you say the amp is grainy what exactly does that mean?

Should i lower the low, mid and high or the bass and treble too? They both are similar in terms of frequency but 2 different settings on the HU.

What about the amp input level, is it set correctly? I tried increasing the input level to around 1V or 2V but i then the volume needs to be cranked up more from the HU as a result with fader set to 0 stresses the front 4" speakers.

I've tried setting the frequency also in between all the ranges for low, mid and high but wasnt sure if this is the way to do it.

I have 4" dual cones in the front instead of 2-way coax since i had a pair of kenwood KSC-ST30 tweeters already and going for coax would give too much treble.

Theres also an option called NON FAD which I'm not sure about. I have tried it out but dint notice any difference in sound.



And the frequency settings

Hi Vid,

I have same HU & slightly similar setup(2 way sony explode fronts & Pioneer 6X9 at rear) with sony 554ZR amp & 12inch sub

I am using following settings on my HU

The HU settings are as follows with EQ-EX enabled:
Fader:F4
EQ-LOW: +2 (varies from +6 to -6)
EQ-Mid: +4 (varies from +6 to -6)
EQ-High: +4 (varies from +6 to -6)
Bass: +3 (varies from +6 to -6)
Treble: +3 (+6 to -6)
Loud: MID (low, mid, high, off)
Sub W: On at 80 Hz +2(-6 to +6)
HPF: on at 125

Never knew the following settings were configurable, can you tell me how to ? Also what do you mean by "all set to Q1W (2N,1N,1W,2W) for Q-factor settings."

Quote:
frequency settings:
Low: 80Hz (40,80,100,160Hz)
Mid: 1KHz (200,500,1K,2KHz)
High: 10K (3k,8k,10k,12kHz)
all set to Q1W (2N,1N,1W,2W) for Q-factor settings.
Bass frequency: 100Hz (40,63,100,160Hz)
Treble frequency: 6KHz (2K,4k,6k,10KHz)
Thanks

Hey Technocrat,

Thats the best part of the tuning all the frequency settings and adjusting the Q-point of the frequency curve. They have a small but very discernible effect on the sound.

To enable EQ-EX you need to be in custom mode, then keep the SW button on the HU pressed, the EQ-EX light will turn on on the display unless it's already on in which case it will go off. You need to make sure it's on.

Once the EQ-EX light is ON you need to keep the AUDIO button pressed for a few seconds and a new menu comes up with all the frequency settings.

Using these settings you can change the shape of the curve to suit your listening. There are various center frequency option with which you can play around with here.

The Q-point can be configured to 4 positions 1N being the narrowest curve and 2W being the widest curve.

This Q-point is for your high, mid and low frequencies. If you want a tight output then it should be set to narrow (1N or 2N) so the curve will be narrow around the center frequency if you want it a little loose then you can select wide (1W or 2W) to get a wide curve around the center frequency.

Go ahead play around with it. It's a lot of fun.

if you are on a tight budget bridge a sony 502/552. it wont make a lot of noise but it will drive the sub ok.

like i said a 40liter sealed box is a good place to start.

tone controls should NOT be used a volume control. by setting all your controls to +3 or +4 all you are doing is increasing the entire level. First set all your controls to 0. then raise the volume level to a level you normally listen at. then boost/cut each frequency to taste.

it does make more sense to let the HU be "cranked up". if your 4" speakers are overloading is it due to excessive bass and this can be rectified either be using the fader or by using bass blockers (a pair of 470uf electrolytic caps wires back to back).

The Non Fad option if for the subwoofer. this is so that the subwoofer level remains constant and does not fade as you fade front rear to front.

@vid6639: Man its been excatly one year now that I got this HU & am still finding more & more features, I can not express how much happy I am with it infact so much that I plan to keep this one till the time it gives up on me

I know the rest of the settings i.e. EQ-EX & custom mode etc even the various options when audio button is pressed with HU off & even I wasn't sure of the various option there like the NON-FAD but nice to know

Hmm is fiddling with these settings dangerous? I mean my fronts aren't powered by amp & I have kept the fader slightly front to get front soundstage. So I hope I dont burn the fronts, dont know whether this would matter but just asking since I dont know.

Navinji that's why i settled for +3,+4,+3 for low, mid high instead of full +6. That would just increase the level so i settled for a mid band value. Anyways, shall reduce all to 0 and tune it after that.

I'll increase the input level of the amp. that way the rear sound will reduce and put the fader to the rear that way the front should still be little better.

The 470uF caps would filter out the low frequencies. Till what frequency will it filter out to?

2 x 470uf/63V in series (back to back) makes 235uf. ginve your speakers are 4 ohms nominal it would filter out stuff below about 150Hz at 6db/octave.

Guys, I am getting an Alpine 9830 here in Pune for Rs. 14,500 with B/W the other considered option is a Pioneer 6850 without B/W (Rs. 9100/-) . Which one should I go for?
The setup is:
Front components - JBL GTO 607
Rear 6x9's - JBL GTO 937
Speaker Cables - Monster
(No amp)
__________________________________________________ __________

Upgrade planned in December -
Amp - JBL GTO 75.4 (Front components and Rear ovals)
__________________________________________________ __________

Upgrade in March -
Subwoofer - JBL GTO 1204BR (Dealer is too excited to sell the Bass Reflex box)
Amp - JBL GTO 300.1

Any other suggestions for sub woofers?

moralfibre, you look pretty set, buddy. That's a real good system you got planned out there.

Personally, I would go for the Alpine. I think with the speakers+amps you got planned, the Alpine would fit in better with better SQ to complement the speakers & amp. And a grey Pioneer is a no-no anyway.

And for the Sub's amp, don't you mean the CS300.1?

And after you're done, do post the details (and some snaps if you can) in the "What ICE & at what Price" thread. It will be of help to others looking to setup their ICE.

BTW, what car are you getting the ICE done in?

The car is a Fiat Palio 1.6 Sport which I took delivery of yesterday. I am sorry I meant the CS 300.1 .

I will be starting off with a basic system and then upgrade slowly. I am still unsure whether I should go for a bass reflex box.

Can someone please guide me for installation of 6" speakers in the front door pods of the Palio? The stock size is 5.25" and most of the dealers do not know alterations that need to be carried out.
