does it really damage amps mounting them to boxes

[PaulD 10+ year member]

I did not say that there's a magical place to mount your amp...lol. I just stated that mounting a amp to the sub box is an inferior place, in my prospective.

And he (and others) is saying that if the box is built right, the vibrations are going to be same thru most of the car as on the actual box.

The circuit boards in amps are fiberglass layers that are epoxied together, I was not aware that they used silicone. That glossy cover on your ECU board is a conformal coating to "weatherproof" it. Most all of the military hardware I have seen uses the CC.

it's too late to come in here with all this technical jargon, no one knows what were talking about, plus someone already closed this thread //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I hear what your saying, but......//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

What ? where did you see me say this ?????//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif...lol

yes i see your point, but how come I have seen amps fall apart for being mounted to the box or in a inferior place with lots of vibrations and they were not cheap amplifiers ?

I have built many boxes and I never cheap of on the materials and I still find it inferior. I use lots of braces and at least 3/4'' MDF when building boxes.

I see what you maen...lol. I did'nt mean fall right apart in to peices I meant the internal part of the amp.//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

But you also believe there is a such thing as 'digital' amplification so your opinion currently does not count for much.

What ? Have ever worked on a class d amplifer ? probaly not. There are 3 diffrent kinds of class d amps there buddie, the analog, digital and the intergrated clip amps that are class T.

Analog-controlled class D. Switching amplifiers with an analog input signal and an analog control system. Normally some degree of feedback error correction is present.

Digitally controlled class D. Amplifiers with a digitally generated control that switches a power stage. No error control is present. Those that do have an error control can be shown to be topologically equivalent to an analog-controlled class D with a DAC in front.

Exactly digital control class d. Just because it has a digital controller does not make it digital. It still outputs analog signal.

You really should have read the whole article. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

its still processes the signal a little different.

Yes but it should in no way have an effect on sound.

i keep asking and nobody has yet to say, where is this magical vibration free zone in a car with your average substage! cmon' i got the screwgun in hand ready to go!!!

I pretty much answered you on my post in page 2.

Basically I said each car is different and the spot with the least vibration in my car,

happens to be the Front of the Box.

here is what I said on page 2.

ever notice that different spots vibrate more or less violent in the car?

each car builds pressure and flexes differently.

my dash vibrates like crazy and I do 153s on the windshield.

My back seat area doesnt vibrate at all and I measure high 138s back there. Thats where my amp is mounted.

My box is in the rear cargo area.

I put my termlab sensor on the front of my baffle next to my subs, and I do about 142, with almost no sympathetic vibration on the baffle, just the air.

I can do 154dB on the back hatch glass.

The point is, your box shouldnt flex, and if you are worried about the actual SPL vibrating the amp, your SPL would be alot lower right on the box as compared to say the ceiling or dash.

 

[Mass Car Audio 10+ year member]

good point, just make sure the box is built good and strong with thick MDF and lots of braces.

 

[fatboyracing 10+ year member]

well thanks for the input but it looks like no one really knows this needs to go on myth busters

my box has alot of braces so I think I am going to mount it on the box cant vibraite any more there then anywhere else

im driving a chevy 1500 extended cab truck. im going to have two amps and very little space. my subs are gonna be sitting on my back seat. where should i put my amps? one will fit under the back bench seat.. not sure where the other one will go.
