A q for you. Is JBL 301.1 'Made in China' ?

Thanks amigo.

Yes it is made in China.

BTW I'm sorry if this causes heartburn for any bangy boys...

lol Hi Gunman. Arrey 2 extremes happened. First Loveboat to goa, then mountain country in Himachal/uttaranchal. More on that later.
Thanks for the warm welcome

Ahahahaha! Nobody objected to the old mans highly technical response when he was a regular citizen here either. Even if they did, they would get a highly technical response, nonetheless.

How do we acheive a deep filter(not shallow), i mean 12dB/octave or more?

Lastly, what does the bypass capacitors do(and How)? you can explain me in as much detail, because you are moderator now, and nobody will object to your highly technical response.

1. caps is series act like resistors and inductors in parallel i.e take 2 x 500uf caps is series and you get 250uf. electrolytic polaried caps are not expensive but only 2 can be back to back. 2 x 500uf caps in parallel and you get 1000uf!

2. the bass blocker is effectilvely a high pass filter (high pass = low stop)

3. deeper filters can be achieved by using a series of caps and inductors. i am travelling as we speak so i am not going to go into the gory details on this here. if you want more see this link...

4. bypass caps are used primarily to resolve the audible distortions of some lesser capacitors (like polarised, electrolytic etc..). Elliot's website delves into this in detail http://sound.westhost.com/articles/capacitors.htm

5. even i am a moderator it does not give me the right to fill this thread with garbage. in any case I am also moderated (by my colleagues).

Sam you seem to think of my responses as brain candy (your words). Others find it so much gobeltygook. Some even questioned if I was here just to show off. Believe me, i had no intention of showing off after all this is the ICE section of a predominantly Car forum.

So after those responses I am a bit more circumspect in my responses. Hope tou understand. BTW want any thing from Singapore? small. bags are quite full thanks to the 4 x 5kg OPTs.

Given that one thing one should keep in mind. 2 good speakers will sound better than 4 bad ones. A good HU will sound better (if less loud) than a lesser HU and a poor amp.

now to see what we can salvage of this...
My friend has installed the following setup in his Indigo.
Pioneer 6991 rears, Boss 4 inch fronts, Boss Ripper 12" Amp and Desi Alpine 4 channel Amp.

I assume the Ripper a Subwoofer not an amp.

With this setup the 4" boss fronts will be virtually not heard esp since the 6991 are in parallel with them (so you cant fade them down). The 6991 will be helped by the 12" Ripper.

what i would do...

1. make sure the HU allow you to use the rear speaker out and line level out at the same time and your sub as a LP filter for atleast the rear.
2. then run the front BOSS and Sub (2 ch. bridged) of the amp (front and rear line level out)
3. run the 6991 from the HU. the 6991 is the most efficeint of these speakers. it requires the least power.

Thank you very much for reminding me how poor I am ! I am glad that I am able to understand something from ur technical views - You want me to run fronts and Sub via the Amp and the Rears on HU - Correct?
Now Is there anything else I need to instruct the installation guy about? Fader Effects, Wiring, Whatever etc? Kindly let me know. Also suggest a good Sub and an Amp within the budget of Rs 6000-7K. Thank you.

first of all thank you, for being patient with my weird queries.
Secondly, c'mon Navin, i know by now what a bass blocker do i.e it acts as a HPF

what i meant in my question was, when i connect 3 such non-polar caps(of 235uF) in parallel (each of which is made out by connecting two 470uF electrolytic caps bk-to-bk) would this bass blocker work or not?

Hi! I havent had the time to read the previous part but i want to bring one thing to your notice.
When you connect capacitors in parallel, their capacitance is halved. When you connect them in parallel, the capacitance is doubled.
If you connect 3 235mfd caps (made by connecting 470mfds b2b) the total capacitance is 705mfd. This will change the frequencies passing through this bass blocker.

why do you want a Xo of 56Hz. you will hardly notice any change. in any case if you wanted a lower F3 i'd take 2 1000uf caps back to back to get 500uf and use that instead.

Hey was this a cram all I can competition?? Looks like the whole interior has been rebuilt...... Awesome!

[Harrie]

Hmmm... Didnt know this car was sponsored by you sam! Definitely the hottest one around now. How come you chose him over more senior people like Niyas and Nazir?

[Sam Kapasi]

All a question of enthusiasm my friend. Let me show you why

Take a look at his showcase.


Now you know why

thats exactly what I was wondering on.... I have seen Nazir's is more inclined towards Boston nowadays.... is that a reason ? Anyways, nice to see a car I see everyday getting featured here

I can see now ... Do you visit Coimbatore often ?
