I'm not sure what I did, but my power cable to the amp got disconected. The sub played screwy for a bit, then I turned the car off. Reconected the cable, and it made a tiny spark. Turned the car back on and theres no sound. I looked at the sub... and
the woofer cone is sucked all the way back!
WTF!
How the hell do i fix this??
Thanks!

I could see it pushing OUT of the track.. but not sucking all the way in. |

Amps put out ac power, thus the in and out movement and it reverses magnetic polarity on the voice coil.
If you shut off the car does the sub come back to normal resting?
If so reverse the phase(swap + and -) on the amp, turn on the amp, if it pushes all the way out, try diconnecting the RCA's from you amp, if it still pushes out you amp is fried, or messed up.
If when you disconnect the RCA's it returns to normal then you deckis sending a signal to the amp. |

| my guess is its blown? i have a single 15 in my room that used to be able to be pushed down a good 3 inches...it is now blown and doesn't move more than an inch |

Check all your fuses. That spark can sometimes make a fuse go poof! It's the absolute first thing you should do before spending money on replacement stuff :D
Edit: I didn't see the part about your sub being sucked back. I can't help ya with that, but maybe reconnecting the power will help :dunno: |

| a shorted cap in the preamp stage can cause that... you'll be drawing lots of power as soon as the amp is turned on. must... isolate the amp rom the deck first, absolutely... especially of the RCA's are routed past something sharp on their way to the back of the car. I've seen some badly cut cables routed improperly, or even from too much cramming of wires behind the deck. |
