Why did my sub blow?

[eclipse3130 10+ year member]

Re-do haha.

New 2012 model alpine type r 10" with an alpine mrx-m100 amp(1000 watts rms to the sub) Bass boost setting on 0. Gain professionally set + turned down a hair from there. Properly "broke in" 5-8 hours of nothing more than 1/2 settings and volume. It just blew out today at about 16-20 hours played. Was playing it in 80 degree weather heavily. All deck bass settings on max with volume about 3/4th way up. What really caused my sub to blow.. Was it just a bad sub or what. And yes the gain was properly set.

"All deck bass settings on max " i would say that is your problem right there

^^This. Your gain on your amp may have been set correctly, but your signal was more than likely clipped being sent out of your HU, well before it even got to your amp.

If you gains are set with your bass setting on low, upping you bass setting will change how your gains should be set..

That and the possibility of clipping from your deck.

Yeah but I had the guy specifically set the gain when the deck was on max, that was the point haha, not going to listen to it on low deck settings. And like I said I turned the gain down a hair from what he set it at.

Can it still be clipped even though the gain was set with deck settings up max? I need to know what I did wrong so I don't blow another one

You are clipping your signal...point blank period. Follow our guidelines in the other thread.

correct me if i'm wrong, but if someone set the gains with HU bass at 0 and 3/4 volume and you max the bass even on the HU, you basically defeated the original gain setting? or perhaps loss of cone control below vent tuning?

You just answered your own question

Do you understand what clipping is?

Yes...

I set the gains with HU bass at max, and volume at 32/35

Your amp is not the only device in your signal chain. Any processing device has the possibility to cause distortion, or clipping. In this case, you turning the bass settings all the way up more than likely fed a distorted signal to your amp. Your amp amplifies what it is fed. Your amp itself may not have been adding any distortion, but how do you know the signal coming out of your amp wasn't distorted? Did you test it in any way?

And how exactly did it blow? What did it do?

Your deck is probably sending a "dirty signal" to your sub, or a clipped signal. It won't matter what your gains are at if the signal is getting clipped your subs are getting wrecked.
