Just too much action in my ICE journey...I say! So much so that I think the time has come for a dedicated thread to track it properly. Every now and then, I have questions that need answers so I might as well seek and track'em all here.

Cutting the long story short, I'm taking it step by step, got the HU first (Kenwood 8016BT) and then went onto the front components (DD CS 6.5) but not without some ICE excitement, you can track that story here

Setup Specs
-----------
Head Unit- Kenwood 8016BT
Front comps - Digital Design CS 6.5
Rear Coax - Pioneer (5 yr old) in a box
Amp - None
Sub - None

I am already onto the next step, experiencing the joys of some high quality, clear, detailed music on the front components. I spend any free time available reading up stuff (threads on the forum/ outside) on amplifiers, while I feel empowered by all the knowldge (theoritical...to be precise), I feel no better or worse... I think I still don't quite know what I am looking for! I think some more due dilligence is required from my side. While I am at it, I keep exploring my HU (awesome features..man!), I quite like the articulation DD's throw up with each setting change. I the middle of it all this caught my attention in a big way and quite rightly so...


Problem - Ad-hoc sound dipping experienced. It starts by sound getting garbled (sounds like wires shorting) a bit while the volume progressively lowers and then after 3-5 secs it recovers in a smooth fashion. I may have experienced it say once or twice earlier in last 6 months, as I was in a continous testing mode (different sources, different genres, different settings), I think I may have confused it with wrong settings and fiddled around to correct it. But in the last 2-3 days the occurances have increased, it happened 4-5 times in 1 hr of audio listening. As of now, I'm unable to recreate the sound dipping it at will though, pretty much adhoc

As much as I could observe, the sound dip happened during braking (soft / hard) or during Recovery (speeding after breaking). Funny thing, I drove around and played two hours of solid mid bass music today, just couldnt recreate the sound dip. The only difference from yesterday is that it rained in delhi and its much cooler, I never got around using the AC today. Is my HU feeling the heat or is it a power supply problem. I am a tad surprised considering there's no amplifier sucking the power (much as it was in GTO's case).

The only thing changed in the last one week is the fact, that I got new front components, could loose cables be an issue ?

I think I need to get this checked asap !

The sound dipping you are experiencing might be same as discussed here.
My new Kenwood eXcelon KDC-X994... - Page 4 - DIYMA.com

Its an issue with the HU. Make sure supreme setting is off on the HU!

Okay, my first reaction to that is "Whoaa..how come this link never showed up on my google search !"

On the issue, I still can't recreate it nor have I experienced it again. I did go thru the link and yeah it feels like the internal amp heating up and reacting.

Some other observations to share:

- Volume setting as reported in the thread, It doesn't happen at 22 or 23 rather mine happened at 27 which is the usual sweet spot for this unit.
- I don't use supreme+ on the settings, it just becomes too bright for my taste, atleast it hasn't been ON since the time I got the front components.
- If there is one thing that stands out in the last 3 days its the heavy usage of the DSP on the HU, I have been toggling between the two settings ( with or without DSP) to understand the direction of sound stage and Digital time Alignment features on the HU.

Ques:

- Considering you are well acquainted with this HU ( a la Sumit) , have you had a first hand exprience with this ?
- What are chances of it happening even with an external amp ? any experience here ?
- If it is what we think it is...the internal amp heating up, the installer can't do a thing, can he ! Should I approach kenwood for a replacement, considering others have done that ?

1. Yes i have used the same/similar HU (x794/x7016 ) in my car and a lot of my friends / bhpians cars (SumitBahl, thelord, chiragh_bir etc).

2. I always suggest to get an external amp to drive any kind of speaker and i have no experience with speakers running on internal amp of HU!

3. Yes you should contact Kenwood for replacement.

Question:
When do you feel the sound dipping occurs the most with DSP through / bypass ?

Please come in for a checkup.

Regards

Sound dipping as when its experienced is when te setting is through the DSP, which means DSP active or ON !

Yes sir...will do that asap !

Did your issue got resolved? I have the same player got from Middle East and the problems you are facing is making me worry.

Hey Vijay, apologies for a late response to your query, I haven't experienced the problem since I posted last on this thread. I have tried recreating the problem, but I am unable to do so. Frankly, I don't think there's any reason for you to change your mind. Its a pretty decent HU and is working fine for me.

I have the 8016 BT doing duty since nearly 8 months now .Except for some minor issue due to shorting of amp leads .The problem mentioned here has never happened with Me . I am running 1004 and 7001 JBL amps and all speakers on 1004 and woofer on 7001 .
May be it is happening because the internal amp of stereo heats up goes in to safe mode and after cooling down you again find it fine .

I am getting myself a 8016BT. Haven't decided on the front coaxials & the rear components. Initially it's going to be no sub & no amp.
How has the performance been for you before you upgraded your setup with an amp? & after?

I am using it since 4 months now.Works perfectly with DSP. No problems at all. I am running only rear speakers off the HU.
I am satisfied. :) Worth it !

Avinash,

Its been a year plus with the HU and the experience has been very good overall. As of now, No amp no sub. I miss the deep bass once in a while...but what the hell, the whole setup sounds so sweet. I haven't yet felt the urgent need to get the amp and the sub !
