But the same 'ding dong' people have still not replaced a dead Optima yellow top for me. Grr.

Actually, to be fair, they did. They gave me a 'replacement' 3-4 months ago that was a dud. Measured 8V right out of the box and wouldnt charge. Double Grrr.

at least it can charge your phone when there is no electricity. by the time this happens, the battery v will drop to 4-5 volts lol.

there is a "dong dong" shop in prabhadevi opposite the passport office. the give good service. if you have all the papers they should co-operate.

So Cap in my IMHO is like bling stuff not for real use.

aah, yes.. you're right.. thanks for the explanation

cheers

sorry lbm, didn't see your reply

Ohh yes, power cables come first.. they make a huge difference..

Consider an amp that delivers 100 watts at 14.4v and 80 watts at 12v, in db that difference is negligible. Now add to this that a subwoofer would probabaly be already compressing (due to the limites of it's Xmax at low frequencies) at these power levels and that the human ear ability to perceive differences in intensity for shorter intervals is limited this theoretical increase in power is hardly noticed by your ears.

Yes if the your headlights are dimming significantly a cap might be handy (to keep your headlight levels more stable) but only after the battery, alternator and Big 3 are addressed first.

yeah, i believe the human ear can perceive differences of 3db and upwards.. thanks for the well laid out explanation navin, now everything is clear..

as they say what's written in the books isnt always right, one has to be practical..

btw, what does the Big3 consist of? (pardon my ignorance)

Then lets hope it drives my two 12" good.

Duty is not a problem, as it our duty to pay duty. As far as bribe is concerned..toh "Rishvat lene hai nahi....balki dena bhi paap hai"

Not tried that. I just want a replaced battery for now.

For Optima, the authorized service point is Four Seasons. But its no fault of theirs. I know the people there very well, and they would have given me a replacement from their stock if they had one. Culprit is Amara Raja India. Even emails go unanswered. Polite emails. Really. At least the initial ones.

Sam bhai, Any idea where i can get the bosch batteries??

blueraven some more information on the battery please......

Price, Amps? ANy contact in Mumbai where i can get these

That makes 2 of us, they have goofed up on two batteries for me, after the first bat failed they sent it back after rechaging, it failed again after 15 das and they recharged it, I refused to accept and don't even think they will replace.
Second battery in my cousin's Skoda died and the scene is the same.
HORRIBLE SERVICE !!

The bat is 800 Amps. Should cost you around Rs 15000 to Import one from the USA.
They are not available in India, and I don't know who represents them. I had bought a load of Stinger long ago, which is all over now, that's it.
Good batteries and this one I felt was truly good for Audio IMO.

Yes i too agree with LBM....caps really dont make a lot of difference.

See my brother is getting the stuff from one of the very reupted installed in USA, involved in serious SPL competitions. He happends to have quite a few SPL records under his belt.
Now this guy invited my brother to a SPL show, sometime back. To my bro's surpise none of the SPL car there had caps installed in them. All those guys concentrated on was batteries, alternators, wires.

Morover, i may be wrong, but from 2500 watt system , what will a 1 or 2 fard cap do? I mean i dont think it can store amount of current required to properly power a 2500 amp.

I thought Deepak did not represent Stinger anymore. anyway I just wanted to clarify for all concerned (on this forum) that you did not. As a mod I have to ensure that. I hope you understand.
