anybody else have overheat problems with an AVA250? (1 Viewer)

[Philip_G]

if I'm driving the sub hard for any length of time (say over 20 minutes) it overheats unless I put a fan blowing air across it.
the sub is a shiva 12, paralleled to the ava 250, so shouldn't be a load problem. Has anyone mounted a cooling fan on the heatsink?

I haven't had mine for long. But I have it hooked up to a Tempest with the voice coils wired in parallel and haven't had any problems so far. Mine is even mounted on the side of a sonotube in a rather small enclosure (mind you the enclosure has thirty two 3/8" holes drilled in it). Over an hour of music and several movies over the last several nights hasn't had it get more than just warm to the touch.

Movies seem ok, it's just long periods of loud music, granted I do have the gain on the amp turned ALL the way up (what can I say I like bass) it's warm to the touch always from what i've noticed, it's mounted to the back of a small sealed enclosure, the amp has like 3 feet of airspace between it and the nearest object, and the room's a steady 72 degrees... I'm just wondering if there isn't something wrong..

No overheating problems here.

What do you mean by "overheat"?

 

[Philip_G]

overheat=amp gets too hot and shuts off.

 

[Jack Gilvey]

Ok, you didn't state that it's shutting off on you. Ask DanW. at Adire about it, that's not a common problem with the AVA250.

 

[Philip_G]

sorry. usually that's the only indication it's too warm. At least I'm assuming it's a thermal protection thing

Philip,
It is possible there is a problem with the amp; however, are you running it consistently into clipping? This can greatly increase the heat dissipated in the amplifier itself (as well as play havoc with the driver).
If you would like to exchange your amplifier, please call us at 206-789-2919. If no one answers (we're typically on another line or down in the warehouse), please leave a message for Brian Bishop, and he'll arrange a swap of your amp.
Thanks,
Dan Wiggins
