SOURCE: bridging to 12 inch kicker competition subs to my 1000 watt alpine 4 channel amp
I'm a bit confused. For Alpine amps, the "M" prefix is for monoblock (aka single channel) amps and the "F" prefix is for multichannel amps. The only M550 I find is an MRD-M550, which is a monoblock, not a 4 channel like you say.
Unfortunately, I can't give you accurate help until we know weather it's truly 1 channel or 4 channel. Then I'll be glad to help!
SOURCE: Kicker sub wont work
Im guessing that it is possibly blown... either you ran too much power to it, or it was hooked up wrong... you should unscrew the sub from the box and look inside to make sure that it is connected correctly.... positive to positive, negative to negative,,, if they so much as touched then the L7 could very well be blown.... smell the magnet and if you smell a burnt smell... it is blown... maybe turn your amp down a little... its possible that it is also in protect mode because you are running too many watts to the amp. Feel free to ask if you have any other questions.... Please rate! :D And good luck... i really hope its not burnt out. that stuff is not cheap.

if the amp is a 2 channel, u could either bridge them all, or if you wanted to, you could hook 2 speakers to the two seperate channels, and then hook the other one to the negative on one channel and the possitive on the other. if this wasnt what you meant, just, try to tell me more about the amp... thanks

Connect one to each channel, for the best sound.

SOURCE: only one voice coil is working on my L7 10
If the tinsil wires all look good then chances are you broke a lead in the coil, the only way I know of to fix this is to order new voice coils and a new spider and replace them..
There are places on the web to order parts, you just need to take good measurments of the parts and relay them to the stores.
