just recently my kicker 12" l7 has no bass coming from it at all.. the amp power is on and tested the channel connections on the amp to check that the amp was running at 1 ohm since its a mono, and it was. i checked the connections from the outside of the box that connect to the subwoofer and they were good.. i dont know what else to check!
Try using different rc wires from deck to amp.Plus you could have lose rc wires on the back of your deck. If that isn't it take sub out of bow and check the termanal wire the speacker wire goes to fallow it to see if it broke off where it goes into the sub.I have seen it break right before it goes into the sub before.Before you take you rc wires off on move them around to see if you get sound,that will tell you it's the rc wire at the amp then check behind the radio.But before you take the deck out turn your system up and go to you sub and push it in and if it starts working you have a broken or mess up wire in sub.If it is under warrenty take it back.Any more problems e mail me.

Check your RCA cables to make sure you are getting signal. The amp isn't in protection is it? Also, if you have a multimeter, you can check to see if you are getting any power out to the speakers. Also, check to make sure your subs aren't blown. Keep me posted.
On the amp there should be High pass and a low pass setting. Put it on low pass cause if its on high pass or in between it produces normal noted like a speaker. Low pass will filter out all the high frequencies.
It depends on the specific subs and exactly what you want out of them. You have practically unlimited choices for amps.
The 10" L7 has a power range of from 30-600 watts RMS, the 12" from 50-750 watts, and the 15" from 100-1000 watts.
So if you have the 10's, you would want an amp that puts out at least 90 watts RMS and not more that 1,800. Unless you are really into SPL and have an unlimited budget, it's probably best to go somewhere in between.
Keep in mind that these Kickers need to be in a proper enclosure. They like a little more volume to work as compared to RF's or MTX's and some others.
As stated before, knowing the impedance of your subwoofer would really help the situation. Either way the link I have provided is to your subwoofers manual (Incase you dont have it)
But since you have said it has smoked, if it still works I recommend turning the bass boost down (Bass boost causes alot of heat within the subwoofers voice coil and even within the amp itself and should never be maxed out.)
Here is a link to your manual for the subwoofer. http://www.kicker.com/sites/default/files/SoloBaricL7Series.pdf
So as a solution to your issue, keep your bass boost turned down. You should almost never need it if you have tuned your amp correctly (You have a very serious subwoofer there)
Consider yourself lucky if your subwoofer is still working without issues.
common problem of this subs are in the litles cables that goes to the voice coil. few times brock....check those.
another .....if you heard the music too hihg with many bass..and your amp ..i think is big block... may be you blow off!!!!!!!!!
the voice coil and the little wires...im calling trencillas...are the aquiles talon of this L7 and a manny others kickers.
check the ¨TRENCILLAS¨ FIRST.
