Blown sub?

[AlexBoomin]

I need help discovering why my sub is now blown. Quick series of events:
1. I noticed amp light dimming when the bass hit but no other dash lights or headlights were dimming.. just the amp power light.
2. The fuse on my 4guage wire under the hood blew out
3. I was smelling a weird smell sort of like a burning smell but not really, and then now everytime the sub is hitting the middle of the sub sounds like it’s rattling (definitely blown)

I’m matching RMS wattage from my 12” Skar to my 800.1D skar mono amp.

*The amp gain was only turned up about 60-70%

This comment suggests you do not understand the proper way to set gains, and is probably the problem.

No I don’t have a clue actually. I just know what type of sound I want to hear but have no idea how to get there.

60-70% gain may be way too high given your h/u's output voltage and the sensitive in your amplifier. I can't confirm every detail in this video as I just looked at it briefly, but it appears to give the basics of setting your gains properly...



Not sure when or why the gain setting tutorial on this site was removed, I use to link to it often for these types of questions. Anyway, hope that video helps you.
