That's a very nice ice setup you've got! How's the experience after the damping? Has the outside noice reduced dramatically or is it a minor change? Have you tried driving without the music system on to check the quietness levels?

Can you list the items which you purchased online?
Yes I did, The SubWoofer,Mono Amp & the Components were sourced from Snapdeal.

Thanks nishanth.I have felt that the music has become more clear and the sound from outside has reduced pretty well.

However to be honest ,I have not tried with the music system off so would be hard to judge,but I feel a small reduction in the engine noise outside than I used to hear earlier.

Congrats BIBIN, What type of music do you listen to ? do you have more pictures taken on the electricals side how power is extracted from the LA battery leads directly to power the Sub Woofer Amplifier.

Have you confirmed once on the factory warranty part, though we are all aware that as long as we don't touch cut or strip any part of the factory wiring harness we are good, but again the power extraction from battery can in fact put a load on the alternator directly or indriectly, will that not be a point for the SA to complain breach of warranty as part of 3rd party ICE install

As far as I know, wiring harnesses were used and no wires cut and hence this should not void warranty. However I have not checked with Toyota dealership on this and hence I'm not sure on that.But I have seen quite a lot of vehicles in the SC for regular service who have got high end installs along with headrest monitor etc. I believe even some of the showrooms do ICE installation.Never heard of any SA complaining against a void warranty till time though.

Sir, I just noticed that the sub is rated 350W RMS and the amp is 500W RMS.
I think it is bad to overpower, please correct me if I am wrong?

I'm not an expert in this matter. However I think if the amp is rated higher, the gains need to be turn down to limit the output on the amp so that the sub is not overpowered.

Speakers draw the power they need, so it is always better to have a amp rated higher than the speaker's power rating. If the amp is underrated and the speakers are loaded, then it could make the amp to either trip if it has a safety mode or burn. With a higher rated amp you just need to set the gains low which again is good as it will reduse the chances of bringing in floor noise.

The absence of the sub should be felt more than it's presence. If one tunes it like that, there is a massive headroom available to handle low bass. It depends on sensitivity of sub, or how loud the sub sounds. One needs to reduce gain only if one hears slapping (sub reaching end of travel) in the sub at high volume. Otherwise, under normal listening conditions one doesn't have to worry about gain. The amp usually pushes 100-130W through sub.

Incorrect - that is a non-technical explanation. A speaker is a *passive* element, and doesn't *draw* any more or less power. It is the amp which pushes current through the speaker coil based on the impedance of the coil, and the volume level set at HU (in effect, signal level at Pre-out). This current passing through the coil gets converted into sound, with loudness based on sensitivity of the speaker

* It doesn't matter if the speaker power rating is less or more than amp, or even if the amp is rated much more than the speaker

* Amp trips *only* if the device temperature at heat sink exceeds a set value (harmful for the device if it is exceeded). This tripping is reversible, and the amp comes back on after the temperature comes down. This can happen even if the heat sink is dirty, and not necessarily if the power pushed through speakers exceeds a limit

* Whether one has to set gain low or high depends on the Pre-out signal of the HU. It has nothing to do with the amp power rating

* There are 2 ratings of an amp. One where the ouput severely distorts, and another where the device can blow. At the first limit, the output is so bad that one would wish to jump out of the car. The second limit is associated with the thermal cutout - assumes you have not already jumped out of the car when the first limit was crossed

* If the speaker is rated higher than the amp, neither the amp not the speakers will suffer. The listener will, since the amp output will severely distort at it's max rating. The amp will only push current to whatever level it can. No one listens to a system at that condition - it is a guidance value

* If the amp is rated much higher than a speaker, one stands the chance of hearing speaker distortion (reaching end of travel of cone, non-linear cone excursion, etc.) if the power being pushed by amp is too much for speaker to handle. Amp will never distort or trip in this condition

* "Floor noise" in the output is inaudible in a car, which is inherently a very noisy environment. One need not worry about it. The floor and door surface of the car makes much more noise on the road

I don't want to get into an argument.
You have detailed what I have summarised.
Speaker is loaded through the amplifier is what I have mentioned in the post and not vice versa as you have deciphered.
Amps that are rated higher than the speakers are always a safer bet as it leaves a lot of headroom.
Every amp has a SNR ratio, the higher the better, by floor noise I did not mean the physical noise generated in a running car but exceeding the SNR in higher than optimal gain setting which is likely to be set when the RMS rating of the speakers exceed the amplifier RMS rating.

Bibin - congrats on your upgrade. As music aficionado, and one who listens to music in his car most of the time, I would love to do what you have done. However, I do not think I would be able to bear the sight of someone stripping down my Fortuner like that.

Well Der Alter and GKannan - Your posts transport me back to my physics class!

My question, if the amp is rated higher than the speakers what is the risk of blowing the speakers?

That is governed by your ears, and what is in between.

In the region where the amp can overextend the speaker (drive so much power that the cone excursion is more than what it was designed for), the music is no longer music - it is a cacophony of distorted sound. The speaker would still be some time away from the point that the voice coil would be burnt. But, by that time - if you are a keen listener of music - your mind will be fried by the noise!

If one's mind is not affected by this noise, a short while later one can hear the speaker say "He Raaaaaam" and silence after that (it is actually a loud Phut ).

congrats on the install.
I'm looking to upgrade my audio on the fortuner.

Questions

1)XAV-712BT -> was this considered ? looks enticing with its sensitive touch and decent display.


2)AXESSS interface, will it work with the above Sony head unit to enable connectivity with the steering wheels interface.

Also I don't mind using the factory head unit , as I'm not particular about video on the HU and serves my purpose.

would it be possible to have a similar setup as yours minus the head unit with the existing head unit.
