BTW we all forgot about damping. Anyway the ICE forum now has a thread just for this.

The enviroment in the car needs to be damped, isolated and deadened.

Various products help from butyl rubber based sheet (doors, trunk and under carpet) to spray ons (great for underbody). You can never have too dead an enviroment in a car. What with so much acoustically live glass area. So my suggestion is to damp like it is going out of style!

Hi there.,

Been reading a lot of the posts now that I a retired person and some time to my self. What has come to the fore is that there is a lot of first hand knowledge out there that is not being used properly for the benefit of the Brother's and sisters (I hope there are ladies interested in cars as well) out in the BHP world. There should be a thread just for the gurus who give a listing of what was fitted, why it was chosen, how it was fitted, how long it took to fit, how hard or easy it was to fit, HOW MUCH IT COST TO FIT, and where the hardware was bought all with pictures. In this way there should be a benefit for us in as much that these supplier will realise that it is in there own benefit to give a good and fair service for them to be mentioned in such a forum. And this thread over time would come a very powerful reference point for us that dreaming of that great sounding ICE. I am a great believer in market forces and to get a better service from our retailers then we should hold them to account and praise them when are good and belittle them when they are not. From a Lot of the posts there is a fear of getting shoddy goods and services and maybe some of the home grown and some multi national will learn to give warranty that is worth the paper it is written

Hi supernova!

There is such a thread (well almost) where people discuss what they bought, how much they paid for the equipment, pictures of the fitting.

here, take a look with your own eye's.

Hi There
I had a Look at that. But I trying to say is that the gurus are the ones who are fitting them and they can by virtue of their job give a experts opinion on that fitting. With a few comments on how the system sounded in that car. We are only going to sample 1/2/3 cars were you are fitting and testing, after the fit that everything is right, the QUALITY 10/20/30 or more cars and your opinion carries a bit more weight. We the punter will normally give a biased view, slanted to our thinking and pocket, where as the gurus are not they are just fitting what the client has asked and some times we get it wrong no. From your own experience how times is that true.

Gurujis, I still don't understand the concept of ohms in subwoofers.
Can someone explain in layman terms?

ohm's law is the relationship between power, current, volts, and resistance. ohms as commonly used is a unit of measurement for electrical resistance. wiki it... you won't understand until you know what the other terms mean.

for layman's use... if an amp makes 100w @ 4 ohms, and is 2 ohm stable, it will usually be rated for 200w @ 2 ohms. (lesser the resistance, more the power) so a 2 ohm subwoofer connected will give more power.. 200w... whereas a 4 ohm subwoofer will give only 100w. and a 4 ohm DVC with coils connected in parallel will be at 2 ohms and will give 200w.

if you have multiple woofers and amps that go low upto 1 ohm... you can play around. but one should also consider the specs of the subwoofer... they vary at different ohms. and not all amps can drive such low loads of resistance. typically an amp that's 1 ohm stable or 1/2 ohm stable will cost much much more. however it will have nearly twice to 4 times the sound output and also drain the battery much much less. say if the above amp were 1 ohm stable... it would probably be rated 400w @ 1 ohm.

Guruji's if i am wrong please ignore it.There are so many diffierence in installing SPL setup and SQ setup. For that Guruji's have any comments.Comments like selecting speakers,subwoofers,HU,Cables.
