Why did my sub blow??

[Cashman]

I'm runnin 2 12" alpine type R's in a ported box(4ohm speakers). I got the rockford fosgate p1000.1pd amp pushing them with 2 guage power wire. Had my gains tuned perfect everyone that has heard my system always complemented on how loud and clear it sounds. The speakers were bridged(had the speaker wire in the positive all the way to the left and negative all the way to the right). And yesterday i was driving home from the gym and was bumpin and smelt some wires burning so I shut everything off and looked back and saw smoke coming from in from the trunk. So i pulled over and yanked the power wire out of the amp and there was smoke POURING out of one of the ports in the box. I thought my car was going to burn down lol never seen anything like that, it was bad. So that sub is fried and have no idea what could have caused it? any ideas? I'd like to find the problem before i buy a new one. thanks in advance

Easy. You was playing them too hard. What is your amp settings at?

 

[Cashman]

the voice coil wires on the sub are wired in to eachother(black to black and red to red) then the speaker wire out

you might of had your bass boost on , even from your deck you should have bass boost at off or if there is somthing called loud etc etc turn that off. you have to read up on setin your amp gains. for the most part you can do if you set your deck to 3/4 volume and then go head and set your gain. if your box is tune real high and your playin alot of low bass notes for long times that can b a issue. just read up on seting your amp gains. good luck

If smoke came out of your subs you were playing them too hard. You probably need bigger or better subs or to just change your listening habits.

When you upgraded your wire to 2awg. Did you look into it to see WHY your wire was burning. It might have something to do with your entire problem.

is your amp 1 ohm stable ? or 2 ohm stable ?

Even w/o your loud setting on, you can still clip the signal too much. You can simply turn the volume up too much. If you have a sub control, you can turn that up too much and clip the signal. Anything to increase the signal going into your amp can cause clipping. If you changed any setting by turning up something AFTER your gains were set to that specific setting, then you could've easily blown them.

And what exactly do you mean when your 4 gauge wire was burning up?

Where did you have the subwoofer bass set on your HU? anything above 0 is a no no lol.
