Mounting amps to sub enclusure...?

[Mills561 10+ year member]

My plan right now is to have a box that fills the length of the cargo space in and SUV and the box will have an open area (see pic) for the battery, sub amp, and highs amp.

(thanks to MONSONwarrior... stole his idea/pic)

My question is there anything I need to know about mounting the amps to the box? The sub amp will be right against the back wall and the highs amp will either be mounted to the back as well or have a standalone mount in front of the mono amp. Is there something to use to cushion the vibration on the amp? etc

thanks

As long as you have a solid box you should be just fine, if you have excessive vibration due to a weak box then you might have some issues.

Imagine what box flex would do to the internals of an amp //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif I recall this issue especially with 90 degree mosfets they have a tendency to snap easily i believe thats what happened to my buddies sundown 1500d with the older heat sinks.

I wouldnt do that box pocket idea, just toss the amps under the second row on a amp rack and put the second battery behind the seat. The battery will literally only make your depth 2-3 inches less which is not much when you think of all the space your losiing doing your box pocket idea.

The pockets a horrible idea. Dont do it.

If your box is not solid, you are losing acoustic output from your sub, and would likely have some nasty reverberations from the box.

If it is built like it should be then you will have zero box flex and zero vibration. Only in that case would you be okay to mount the amp to a box.

a good way to tell is to put your hand or your ear to the box while its playing at its max. if you feel or hear any sound or vibration then I would consider it to be weak and improperly braced.

mosfets mounted at 90deg are just a big no, no in the world of electricity or electronics. sharp 90 deg bends increases the wires resistance a lot and creates a hot spot/failure point. thats one of the first things they teach in elec\electronics class. I guess I should also say that you should not mount a cheap or poorly designed amp to anywhere where it will see vibration.

eh, i steer clear of mounting them to enclosures

Why not make an amp rack near the box? Maybe have them slanted at like a 45*?

call any amp maker... they will all tell you in 90% of the cases they do not recommend or warranty the amp if it has ever been mounted to a sub enclosure

subsonic harmonics wreak havoc on them...

I've had my sub amp mounted on 5+ enclosure no problem...but the amp isn't technically directly on the box

Use a piece of wood and space the amp out, put some foam or somesort or padding inbetween the wood and the box
