Stereo & Electronics - Blown Sub question?????

Well after only having my new pioneer premier 12 for about a month it for some reason took a dump on me. My question is will it hurt my amp if I leave it hooked up without a sub hooked to it or will i need to disconnect the power turn on wire?

Thanks

I dont think it would hurt anything. You could disconnect power, because it is still drawing power from the car.

It won't hurt anything! Just disconnect the speaker wire from the amp and leave everything else alone. That way when you replace your sub you have less to reconnect.

You can also just pull the fuse for that amplifier.:nod:

+1 thats what i do.

Thanks for the replies. But is there anything that you guys can think of that could of made my sub blow? The sub is rated at 400 watts rms and 1200 peak, and I was running 400 watts rms and 800 peak through it so it makes me think that it wasn't a over powering issue but something else. Anyone have any ideas?

Does the resistance of the sub equal that of the amp? If the sub resistance is less than that of the amp & you were hitting it w/ the subs max RMS, there's your problem.

For example: 400W, 8 Ohm AMP to 400W, 4 Ohm Sub = 400W/(8/4) = 800W
RMS @ the Sub.

I just found out today from a guy at the local audio what I did wrong. I turned up the Low pass filter on my amp up to 240 (not knowing what I was doing) and that caused a lot of distortion and fried my voice coils. I also picked up 2 new memphis 10's today and love em.

That's a lie. It will make it sound like crap but it has nothing to do with why your subwoofer fried. You sent it too much power. Period.

I'm still not sure how that would be possible when the sub is rated to handle 400 watts rms and 1200 max, and my amp only puts out 400 watts rms and 800 max.

if you didn't have your gains set correctly it could have easily clipped the signal causing your sub to blow, also if you were using bass boost it could have done the same thing. bass boost = bad
