 Mounting amp to enclosure

So in your expert opinions, is it a bad idea to mount an amp to an enclosure?  I hear it's bad because the vibrations from the sub will rattle the insides of the amp.  However, I see it done all the time.  I ask because I thing it will save me some space in the trunk especially with an extra battery back there.  Any help will be greatly appreciated.

IF you mount it to the enclosure use an extra baffle to help minimize vibration...the vibration at the subsonic level is what causes them to get fubared...

I suppose I could mount to the backs of the seat.  Only problem with the current set up is that the 15" is like and inch or two away from the back of the seat facing inwards.

you could always mount 12v fans to give your amp more ventilation or cooling.

It should be ok unless if you have a tube amp. I doubt it but if you do, you have to be really careful where you mount it. If you ever look at the US Amp owners manual it talks all about the mounting of the tube amps.

I have one question...Where in your car could you mount an amp where it won't vibrate? I have been in car audio since 1988 and have never encountered a bad amp due to vibration. Heat, yes. Low impedence, yes. Not mounting it and it sliding around the trunk, yes, but never vibration due to being mounted to an enclosure.

well back then we didnt run 1000's of watts either...so it was common practice... anything more than 500 or and I will never do it... shoot chris at DB-r an email... he will tell you how many 10's of thousands he has repaired due to vibration damage..

what do you mean "back then"? I wrote I have been into car audio since 1988, that meant I am still into it.  I am very familiar with 1000W plus amps (read other posts). Maybe you need to look into better built amps (?)

according to him he has repaired 10's of thousands... he has been at it a very long time... and no manufacturer i know of regardless of brand endorses mounting amplifiers to enclosures...in fact most warn against it.....even a saz4500 is gonna fail in time.... it is just physics.... little tiny soft solder joints being subjected to severely high levels of sub-sonic harmonics...it WILL fail...when is the question is all...

I cannot see a problem with mounting on an enclosure, unless your about to push some major amps out of the speaker. I have never had vibration damage on an amplifier, and don't know of anyone who ever has. Just make sure that if the amp is to be seen, that you give it a good display and try to hide the wires well without compromising your wiring setup. In your case, definitely use connectors.

I meant to say, pushing major wattage out of the speakers.

I have seen with my own eyes the effects of harmonic vibration on amplifiers so i wont argue the issue... most companies say in the manual not to do it... they say it for a damn good reason...
