Re: intermitent problem

Yes, the coil's copper wire is broken and making connection just "by chance luck" of being close in proximity. I have actually soldered these breaks, and yes your's can be soldered if the break is clearly visible after sufficient disassembly of coil area. Remember to use emory cloth near the break ends to remove the factory winding varnish and to "tin" the copper ends before they are soldered together. Finish with a good epoxy to bind the repair to eliminate "floating" which may re-break the wires.

I have 2 l7 kicker with a 2000 watt amp not really a good brand though..sometimes the subs work perfekt but sometimes they dnt work as the way they suppose to sound they sound really weak n when im driving...

OK-3 issues here but you already know one lol-you bought a substandard amp for some bad *** power hungry subs---thats your first issue :)

Check the ground for the AMP it shouldn't be any longer than 12" from the amp to its grounding point-Any longer than that and several issues can happen, like poor power to the amp, feedback (winding noise over the speakers, usually changes pitch or frequency with the engines rpm's), intermitant substandard sound (your experiancing this) and coil bounce (your subs move in and out producing little to no sound, you are experiancing this as well)

The same issues can come from the amp not having enough constant power to sustain the subs when they hit repeditivly, to fix this you need to buy a cap and add it to your system- A cap quickly charges using the battery, and supplies the extra umph your amp needs so it can push the subs without starving itself. With the subs you have I recommend a 1.5 to 3 fared capasator

My amp wont power both subs the same

you most likely mess up you wiring... im not sure what ohm resistance your subs are, but if its 2ohm or 4ohm you wire straight foreward one sub all positive wires to left positive, all negitive to left negitive, and the same with sub 2 to the right terminal. BUT if your subs are 8ohm then wire it with all positives from both subs to LEFT positive and wire all negitive wires to RIGHT negitive... and see if that helps and good luck!

Subs cutting out

Agree with Kev. Even if the woven lead wire looks ok, it can still be bad. I unsoldered it, clipped a lil from both ends, and re-soldered it. Works great now.

No Sound from Subwoofer

You should be able to check this yourself pretty easily, Just connect the power and turn it on. Connect an audio cable to the input. Make sure the level control on the sub is turned about halfway up or more. Now, touch your finger to the tip of the plug on the other end of the audio cable. You should get a nice hum out of the subwoofer. If not, then the sub is bad - if it has a user-replaceable fuse you might check that first. If you do get a hum out of it, then the sub is ok, and the problem is elsewhere. Might be a simple as a bad cable or an option on your amp/receiver is set wrong.

Subs stopped working & protect light on the amp is red...

well at this point i would say it is both,, the subs fried because your amplifier passed dc [direct current] and fried the voice coils on your subs....return them if they are under warranty,, the amplifier sound like you either operated it beyound its specifications or it has a defective output stage allowing it to pass or leak turned the voice coils into the equivelent of the runners in a toaster oven....when an amp passes dc it is going to do so to whatever speakers you hook to either bring it to a shop to be fixed/ return it to place purchase for exchange or throw it away.....or you will continue to experience the same problems....I am the amp goes into protection when it detects a short...[ the short is produced by the amp and it is detecting its own fault and putting it in to protection after it BURNS up your drivers....
