is it fried?

[omgitsyou]

Hi im new to the forum but ive been installing car audio since i turned 16(so 2 years). I installed a set up for my friend, he went and got a viper 1200 off of the internet and then baught 2 l7. I hooked it up for him and such, and he's had it for 6 months. Now all of a sudden it popped a fuse. So i replaced the fuse and all it does it flash the protection and get severly hot and bogs down the whole car, like you can hear the alt whining. But the real kicker is the fact that i switch wire with the amp power the speakers(which works) and the amp still does it. SO i'm pretty sure its not a wiring problem. Did the amp just magicly die, i took it appart and didnt see and fried marks.

i took the power and negative straight from the amp powering the speakers and used it to power the amp to see if it was a wiring issue. The amp still went into protect. And then i switch that same power and negative to the speaker amp and the speaker amp worked fine.

A sub could be blown and causing a low impedance overcurrent situation. Disconnect the subs from the amp and replace the fuse. If the amp powers up it is probably an issue with the subs. If the amp still blows the fuse with nothing connected to it, its the amp.

already did without sub, and its not blowing the fuses. The protection light is just flashing, and the amp is getting very hot right at where the power plugs in. And on a side, a wierd thing i had happen was, i had an exacto knife lying on a wire so it was balancing on it next to the amp. and it swayed on the wire with the flashin of the protection light. Is there a magnet in the amp or was it just drawing that much current it caused a magnetic field. I mean it almost kills the car when the amp turns on.
