1gggman1 Posted April 24, 2017 Report Share Posted April 24, 2017 One of my CAB amps is inoperative, I'm running 2 strapped at 2.66 ohm and my older amp... Bought in August 2016... is cutting out with a weird scratchy sound. If I slam the door of the car it cuts back on briefly the repeats the problem. It's still under warranty so I don't want to break the seal to see whats up. The amp appears to have the board shifted in the heatsink about 3/16" one way it had been like this for some time now and I had no problems... what do you think has caused this? I am not going to fix the amp myself... I'm just wondering what can be the possible cause? Link to comment Share on other sites More sharing options...

1gggman1 Posted April 24, 2017 Author Report Share Posted April 24, 2017 Yes, sorta... the amp rack is 1.25" from the actual box to allow for the wire runs. I was hoping that this would insulate it from the worst of the vibrations. What do you think... should it be sufficient? Link to comment Share on other sites More sharing options...
1gggman1 Posted April 24, 2017 Author Report Share Posted April 24, 2017 I suppose I could put a center brace under the amp rack and isolate the amps with rubber bushings as well... this should help...right? It's already attached to the box firmly at the top and sides, you can see this in the pics. Does anyone think all this extra bracing and isolation is necessary? It's only at around 2500 watts or so at 2.66 ohms. Link to comment Share on other sites More sharing options...
Broke_Audio_Addict Posted April 24, 2017 Report Share Posted April 24, 2017 What do you expect from a cheap amp? That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

SkarredSierra Posted April 24, 2017 Report Share Posted April 24, 2017 those amps are garbage. You shouldnt have cheaped out. Now you must pay the price of going cheap. If its still under warranty then get it replaced. Otherwise spend more on better quality. Link to comment Share on other sites More sharing options...
