Gain Setting Tutorial

It looks good...8)

I used to set mine to about 65%...before I took the subs out at least...I was always scared that I would blow out the back window. :twisted: 8)

Here\'s something I hope you can will all use to your benefits.  As you may or may not have noticed, most equipment dies for one simple reason :  Most people push their equipment beyond its limits.  Whether its the amplifier or subwoofer or speakers, clipping is the number one cause of failure that I see.  To prevent clipping, I\'ve made this tutorial (Well, JL Audio did, but I\'ve been doing this for years before they put it on their site).

Okay, before I post the links, there\'s just one problem that I have with the following guide.  It says to use 75% of max volume.  I don\'t agree with this at all because, with some head units, you can crank it up to full without distortion and with others, it may only be 60% ...  To set your gains, use the MAX settings you\'d NORMALLY use ...  If the loudest you listen to your music at on a regular basis is 22/35 with bass @ +3 and treble @ 0 with MX on, by all means use those settings.  Also remember to have the car on ;)  It should also be noted that if you want to use bass boost, set it prior to the gains and use the center frequency of the bass boost (45 Hz for most amps) ...  Please remember that if you have a subwoofer volume control, set it to full before you set the gains on the sub amp ...

Here\'s the formula you\'ll need ...
Sqrt(Power*Resistance) = Voltage
(i.e.  If you bridge a 4 ohm subwoofer to your amplifier that is rated to produce 100 RMS @ 4 ohms in bridged mode, you would want Sqrt(4*100) = 20 volts)

Hopefully, this will all result in greater longevity of your products and cleaner bass.  Some people still insist on cranking the gains after using this tutorial because it\'s \"not as loud as it was.\"  If you choose to do so, you may be putting your equipment at risk.  In the rare case that you find the bass is too much, feel free to turn the gain down.

Could a mod please sticky this ?

I don't get it, whats this for?

I know the "has anyone..." thread are annoying but if i can find two things ill actually do it.

A way around "cold Air" Intakes that suck up hot air from behind the radiator...

Take the Stock Hood and mount a Z31 MK1 Turbo Wart just behind the Left Headlight directly over the Air Box, and cut out the hood from under it. Cut the Top of the Box and Run a  rubber or foam Seal of some kind around the top open edge and make a Intake like a Can Am Muscle of some sort with Ram Air?



Eh i cant read cause like 3 posts up someone said this... Damn

I was thinking of doing this but Premo wouldnt let me get the vent he had.  And I ended up wanting to go with a Naca vent instead.  I dont know if I'll go with any form of a vent.

if you'd like me to remove the pic hessu, just gimme a PM

ya evos dont have anything below the cutout at least not on evo eights i think just engine that shows through

there is something below the cutouts on the evo's ive seen. But, they could have verywell been aftermaket for the mentioned reason of water in the engine bay

you dont think water gets in the engine bay from below?  evo8 or 9 do not have anything under the vent. its also not like they fill the whole engine bay either. water or snow only gets on the engine in about a 4in by 14in rectangle.
