I must say that this is one of the best and most educative thread on ICE I've come across. Kudos to the creator, and contributors for all the info..!

I'm still a n00b on this, and am still a bit confused on how to go about setting things on a bridged mode with 6 OE speakers, and added 2 6x9 rear spkrs + a Blau bass tube.
So, ideally, I guess it'll be all the speakers plus tweeters on channel 1&2, and the Tube on channel 3&4.

Help and Thanks!

What a mess. Why do you feel you need so many speakers?

You got 6 OE speakers + 2 6x9 + a bass tube.

What you might only need is 4 OE speakers + tube or 2 OE speakers + 6x9 + tube.

The best way to connect this would be to connect the front (OE) speakers and bass tube to the amp and the rear speakers (OE or 6x9) to the HU.

Hi,

I want to know the gain setting for my knowledge.

so, i am stuck at which power should i consider either of my speaker or the amp.

Lets say my amp is rated at:-
4x 85w @4 ohms
4x 135w @2 ohms
2x 270w @ 4 ohms Bridged

And my speakers are rated at :-
Front compos:- 100w RMS @ 4ohms
Sub:- 250W RMS @ 4 ohms

so, whos watt should i consider for tuning the gain amps or speaker in this senario?

if your speakers are 4 ohms then the amp will deliver upto 85W to your front speakers and upto 270W to your sub. in most practical situations these thermal ratings are not tested as the speaker distorts due to the physical limitations of it's suspension and surround.

thanks,
but i am asking that should i use the wattage of amp for calculating the gain volts if i am using the DMM or the speaker's wattage?

most amps expect a 2vrms input signal to produce their rated output.

Sir ji, you are not getting my question..

lets say, i want to set gain for the fornt components with DMM. Now, how much volt should i check for 18.43v (as per amps RMS) or 20v (as per compo's RMS)

and again for the sub 32.86 (as per amp RMS) or 31.62 (as per sub RMS)

Why you want to tune the amp what your speakers want tune the amp to adjust the signal they are getting from the HU. Check the first post of this thread.

Use the spec of your Amp and calculate the reading as per the formula given in the first post.

18.43 for components and 32.86 for Sub.

Though this is fail safe method but not the best to tune the amp.

Its important to know this when you decide on what specs to use for gain setting calculation

example 1 - 4 ohm speaker set rated at 75wrms, amp rated at 100wrms @4ohms .... here u would use the speakers 75wrms .. and tune the amp such that it puts out 75wrms - this kind of setup is one with dynamic headroom, where your amp will never be pushed to its limits and will perform real clean and stable.

example 2 - 4ohm speaker set rated at 75wrms, and an amp that puts out 50wrms@4ohmshere since the amp is capable of producing only 50wrms at its full, it will be foolishness to expect it to produce more clean power hence in such a case you should consider the amps rating of 50wrms.

One should match the equipments keeping in mind all these tiny but important details, and then go out shopping it is always better to buy an amp that produces a tad bit more than the speakers can handle, and then set the gains on the amp such that it leaves you headroom, for cleaner and stable performance.
