I take out my sub and amps on a night for security, When I was wiring them this morning I
mad a BIG mistake, yes I wired the live to the neg, and vice-versa ( the fuse on the amp had
been removed) but the live was "live" when I plugged up the phono lead from the head unit
my amp started to smoke, I pulled of all the wire immediately . What damage could I
done??

Ohhhh boy, that's not good as you let the magic smoke out.
Best case sceneario:
1. Hook everything up correctly with main fuse at battery and amp pulled
2. Insert main fuse at BAT, then install amp fuse(s) and try the system
If it works properly, you are very fortunate this time. But expect the amp not to last as long since this event damaged some internal components in the amp.
Worst case: If the amp goes into protect mode or does not turn on, internal damage to amp is likely. Need a service tech to repair the damage. Figure $60.00 bench fees + parts. If the repair costs exceeds about 50% of a new amp, get a new amp.

What have you done? Learned an important lesson.........
that sucks.....

i did that to a punch500s and hooked it right and it worked just fine till it got stolen out of my car

i also did the same on one of my kicker kx600.1s lol, good thing it has protection on it, i was boggled for like an hour turn radio on but amp wouldnt come on, so i went to tap the remote to the pos terminal and this is when i realized that black was hooked to + not good, so i switched it, fliped the key and tada everything worked great, hope it dont cost to much to repair if you have to that route.

Ok
I'm not going to recommend this to everyone. However, some circuit protection devices have mini capacitors in them that store charge, and simple need to be discharged to begin working again.
Here's what you can do.
UNHOOK the positive bat cable from the amp (removing the fuse up front would suffice). Then, take the cover off the amplifier. From there, look for little 'computer chips' in the middle of the amp. NOT on the sides (mosfets), but in the center of the amp. One of those is the circuit protection device. Each 'chip' should have 8 or 10 little 'legs' attached to the board.
From there, take a small piece of speaker wire, and wrap one end to the body ground. The other end, wrap the bare wire to a small nail or screw. Then, touch the screw to each little leg of the computer chips until you get a tiny spark.
YOU'RE GOOD!!!
Put 'er back together, fire it up, and you have a 50% chance it'll work again. Of course, when you open it up, if you see melted circuit board, or exploted capacitors, chances are, your amp is toast. However, if you DON'T see that, it should come back to life.
Did that a few hundred times to a few Earthquake, MA, Audiobahn, Memphis, Crossfire amps...just can't remember which ones that trick worked on.

Nice repair tip there Mr. B. Will file that one away for future references.
Note: Just watch out for power stored in the larger filter caps in the power supply section of the amp. These are usually larger can type electrolytics. Usually, they loose power after the amp is shut off by bleeding off circuits. But, some amps can store power in those caps for days. Probe one of these, and you might get a nice spark at the probe point. (ID: These caps are usually larger than any other devices on the board and often close to a set of torroid type transformers)

Sorry I forgot to tell you that I now have it working ok.
I just rewired it all correctly and turned it on, No problems!.
Thank you all any way for the help and take care.
My Ice is back to Nice!!
