Unfortunately chances are it is a bad sub. but I would hook it up to someone elses amp and then see if it works. Use same power or less for test. If it dont work then I hope you have a warrenty.

I was playing my kicker l7's and aall of the sudden they just stopped working. I checked all of the wiring and it seems to be fine. The amp turns on and works still but the subs dont work at all. Do...

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.

check the fuse on the power wire (+) not the ground wire .. i had a kicker 1500.1 on 2 l7 15\'s and when the bass would hit hard the fuse would vibrate and cause the amp to go into safe mode.. after re wireing the whole truck i then found out it was the 150amp fuse holder

I have a 2008 kicker l7 15 and it hits fine when the volume is mid range but if i go up on the volume it makes this poping sound the amp is tune down

You need to turn DOWN your LPF....(low pass filter). You are driving the sub with a higher Hz than it is rated for. If your amp (or head unit) doesn't have a good LPF, then you are going to do damage to the sub over time.

Please rate if this helped!

My kicker 12 inch solo-baric L7 rattles real bad like something is loose but there is nothing visibly loose what could it be ?

Its blown. Maybe not completely but youve done some damage. If your sure its not hitting the box anywhere and its tight, then thats what it is. Youve burnt the voice coils a little. They regulate how far the sub goes in and out. I have two kicker L7 12s that have bad voice coils. And thats what they do. Theyre in my trunk though so its not to noticeable and they still hit super hard. -->

Also it could be the seal for the box. They wear out and boxes get leaks or weak causing flexibility in the material so when subs hit it vibrates the box really bad. Try removing she speaker from the box then turn it up and see if it makes the noise. If not then its probably the box. Let me know.

How to run the speaker wires to connect to the subwoofer? and does a sub woofer burn if you do not put the right ammount of watts to it for example having an kicker l7 connected to a three houndred watt...

i'm guessing you are having problems with the dual voice coil's so I will link you to the kicker wiring guide... that has the wiring options, you will need a pdf reader **** as adobe or foxit..

Under powering your subs won't hurt them but running a 15 inch l7 at 300 watts is not going to let the sub perform at peak, I would go with a 800 to 1000 watt amp.

15 inch l7 watt's are as follow

rms = 1000
peak = 2000

My Amp Keeps shutting off

You need to get an amp with higher wattage. Obviously, your amp cannot handle those two 10" monsters. hehe Nice Subs though :D

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.

Kicker 750.1 Amp wont play music

it is probably the rca inputs on the amp may have fried. was your cd decked turned up loudly before the power went out? did any wires accidently touch each other? If had worked fine and then suddenly stopped, than either a wire came loose or the inputs fried. try using different cables and I also suggest disconnecting power for 24 hours and then reconnect. If the green light is on then it is getting power and the problem is in the rca cables or the inputs
