Well a friend of mine just bought 2 kicker subs, the the old Left side sub was blown, and the other one was fine, so he bought 2 new kicker subs, and the new Left side kicker blew also, like smoke was comming out,.. so we replaced the left one AGAIN, and now the one on the right dosnt work.. the one on the left is all distorted, what could the problem be?

Sounds to me as though you are WAY overdriving your amplifier.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

With all of the info given so far, I only have one question...What is the brand and power output of the amp, how are the speakers wired, which kicker speakers, how did you set your gains, what are your gains set at?

I am anticipating the gains to be "not even turned up all the way".

Once you answer that 'one' question. We will solve all of your problems. And it sounds as if there could be a few.

There is only ONE way to burn a voice coil, to the point that "smoke comes out", and that is to overpower it. Whether your amp is rated less than, equal to, or more than the woofers a rated to handle, you CANNOT BLOW A WOOFER UNLESS YOU ARE OVERPOWERING IT! I also expect the "my gains are only set half-way" response.

Read this thread... ALL OF IT!

I'm going to assume gains were maxed out and volume was turned up too much to where the sub exceeded its mechanical limits. Ahhh, the beauty of blowing a sub :) Sucks when it happens when you're not purposely trying to blow it...other than that, they make some nice videos.

Do you have seperate gain controls for each channel? U can use a volt meter  connected in parallel with the speaker wire set on ac to set the gains, u just gotta convert the wattage of the speakers to volts and then match the gains( as long as they arent clipping the wave form.) Use a test tone cd when doing this set at 60hz.
