Amp burned up while not playing...really

[shepherd92683]

I call bull on the whole "vibration from being mounted on the enclosure" thing. No matter where you mount your amps, they're susceptible to vibration. Whether it's from the subwoofers output, the bumps in the road, etc. It's going to happen, and rubber insulators on the feet don't do as much as people think. If you can feel vibration, your amp is feeling vibration for sure

So what would your theory be? I already have the amp back and repaired but I'm still thinking its a electronic failure myself. I'm going to raise the amp off the box about 1/4" so it's not directly on it, which will be better.

Sounds like you may have to get creative then haha. My 3500 is under my box. Air flow can be an issue then though.

i don't have a theory, but if vibration were the issue, there would be a lot more amp failures due to vibration. Damn near every amplifier. It could have just been a manufacturers defect in your case.

Here's the finished result and a look at the amount of space I had to work with. It actually didn't take as much effort to make it happen as I thought.

I also agree with reedal, that vibration answer is suspect. I also agree with shade tree. Take a multimeter to your system and check specs.

I agree with the suspect on vibration.... how many competition style 4th order walls have all kinds of amps mounted on the back and sides of the enclosure... if an amp can handle vibration from a 160+ then a 150- should be nothing.... ive only had one amp fail since I entered this hobby back in 1994 and this was 3 years ago wired at 2 ohm and it failed after a long baseball season of nothing but talk radio.... other than this amp "2 ohm but 1 ohm stable mono" all my other amps were always hooked up at lowest recommended load either 1 ohm mono, 2 ohm stereo or 4 ohm bridged...... Ive always had good luck with equipment and I have also never blown a sub or even a door speaker

The saga continues... I had everything going well and just for kicks when I got home I hopped in the back to see if the amp was warm after slamming it for about 20 mins. It was not but the top 2 screws that held my amp to the box snapped off! What else can I do here besides bigger screws which might solve the problem. Starting to run out of options and patience.

As someone who has repaired a large number of amplifiers, I can tell you there is a huge difference between an amplifier being mounted to a box and being violently shook and an amplifier being mounted to the back of a seat and experiencing some vibration.

So cars trucks vans etc that hit 60's and up will all have this problem I assume. I don't know what mine hits, maybe a 49 or 50 let's say. I know that people mount their boxes like that all day long because they have to and I'm sure this may happen but it seems like it should always happen compared to what I run.

the only 60's I've sat in have NOT had their amplifiers where the bass is. Usually their in the rear hatch/trunk where very little vibration goes on. Certain amplifiers are also a LOT more prone to vibration damage than others.

The amount of vibration that could be coming from a box making a 150+ is way more than enough to cause bad vibration damage to an amplifier mounted to it.
