Gain set with DD-1... Subs getting warm after full tilt runs.

Hey guys...

So.. new amp in.. (Hifonics BRX3016)... gains set with DD-1 and checked multiple times.

On some songs, when playing full tilt for ~1-2minutes, I can smell the drivers getting hot. Dust caps get warm to the touch. Typically this is a sign of clipping however everything was set using the DD-1 and has been checked several times.

The amp is rated at 3k (drivers are rated for 1k each) however with impedance rise, I'm only seeing 1700-2k out of the amplifier.

Whats the deal? What am I overlooking? Should I back the amp off a bit more even though the DD-1 is showing a clean signal?

Its only happened on one song thus far (I need dubs - Master P) which hits really low and hard. Drivers are moving a good bit. Perhaps its a boosted version?

Thanks for the input.

DD-1 is a distortion detector. What track did you set the gain with?
And if your playing bass boosted track that aren't clean you'll still see clipping.

I dont recall if this track is boosted or not, was just an idea. As far as I know, its isn't.

I set the amplifier on track 5 (40hz - 10db)

According to the manual, track 5 is a compromise between sound quality and output.

I suppose I'll just keep an eye on it for the time being then. Just wanted to make sure I didn't overlook something.

You are kicking its butt. You set your subs up with track 5. This is your sub woofers signal reference. Different sources can be different levels and even different songs from the same source can be different. It all depends on how it was recorded. This just gets you in the proper range. It is up to the user to correctly use the volume control. I wish Steve would make a dash mount DD-1 so we could see what we are doing all the time.

My money is on clipped source if all other variables are cleared. Play a track you know that's not clipped (anything decaf or got160s for example), lean on it, and see if they still get warm. If they do, something else is going on.

Was this the first time you powered the subs up? And did they only get warm? Just warm? Not hot?
