Sundown Audio

Blown Crescendo 2000d

Recommended Posts

So this morning i'm driving to work listening to music, then all of a sudden I hear a popping sound and the bass kicks off.I turn the radio off and pull over to see whats up and don't see or smell anything burnt up. Check my fuse in the back and its good, check the voltage to the amp and its reading 14.5v like it should, check the resistance to the sub and its at 2 ohms, but I have an idea why I may have blown the amp. I have a D3400 under the hood, a d925 in the back, positive and negative runs of knu cca 1/0, 1 fuse going to each end of the positive run, But i do not have a fuse between the back battery and amp (didn't seem necessary as it was only a 10 inch run. Dumb ass me) and stock alternator. The amp was run at 2 ohms. I cant look at the amp right now since im at work, but daoes anyone have an idea of what I might have fucked up in this amp?

i dont think the fusing is the issue.

the more important question is how was the gain set?

edit: in reality, just pop the bottom off and give it a look over. could be multiple things.

-10 with dd1.

Here's some other details that may or may not be helpful. My car was running 20 minutes with the radio off to warm up the car. When I was checking the amp it was cold as hell. A couple days ago I had to drive a really ruff ass back road to bypass traffic from a wreck.

for one, you should set your bass amp with -5 or 0db. Very rarely is -10 an ok setting, so you were probably clipping depending on how much you had it turned up. Secondly, the amp being cold doesnt mean something wasnt wrong internally from previous statement, i have had amps pop on good voltage while being cold to the touch from clipping hard for a short period.

Yeah that probably wasn't the best of choices on tuning the amp. Hopefully it will be an easy fix.

yea, it is all speculation until you can really get a good look at everything.

Can you get a 3.5mm to rca converter and use your phone as a source unit? Trying to rule out anything with the RCAs/head unit
