Rattling in a P3
yes you have burnt the coil up the rattling you here is the loose wire
RF p2d2 12 smoking
you cooked the coil in the sub when you see smoke you have clipped the sub. improper wiring probably the issue ohms must match gain must be set properly . if you had gain all the way up thats what did it.
At high levels sounds more like a thump than boom
Make sure the GAIN on the amp is not all the way up it is not a loud button. your amp should be tuned to your subs with the GAIN or on some LEVEL. if they are not matched you will clip the amp and subs and blow them.Is it in the proper sized box? is the amp able to run the sub at the ohm it needs to be run at and do you have the the ohm load correct on the sub. there is a lot to it. if your not familiar with it go to youtube and watch some videos there is some good vids there and will help you learn to wire a sub correctly i have enclosed a link easy to use.

Crackling in 1 channel
sounds like the D40D8 transistor the one that stands straight up on the board and not heatsunk! there are two of them. could have a cold solder joint there. have had a few of these problems from people doing hack repairs to them. they look like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290297644906&ssPageName=STRK:MEWNX:IT
Wiring for 2 subs for max performance
This amp is rated at 500 watts into a 4 ohm load bridged mono or 250 watts x 2 into 2 ohm load stereo. Do not go below that impedance in either case. The amp was meant to dissipate a certain amount of power, driving it to hard will lead to damage. Your speakers look like they are dual voice coils @ 4 ohms each. To get the max power while still saving your subs would be to parallel the voice coils on each woofer then run them in stereo with your amp. Stereo 2 ohm is 250 watts per speaker.
Need to know how many ohms this amp is
Safe down to 2 ohms, NOT a 1 ohm stable amp, it will be pushing it hard even at 2ohms but Fosgate's should be able to handle it providing that the install and all cables,wire,connections,etc. are sanitary!
Good Luck !
