I turned my 15" L7 kicker and smoke started to come out the box

there are to ways you can hook these up you can do series or parallel.this will give you an idea. Here is a link that will help you alot http://kicker.com/resistance_formulasget back with me ?

the amplifier is never to much for the sub. If the gain on the amp is turned up to much then that will pop the sub.

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.

The only way to get a new one is to contact Kicker directly, and see if they'll sell you one. Otherwise, you'll need to get another woofer. They only sell the replacement parts for the SoloX woofers. Sorry about that.

i'm guessing you are having problems with the dual voice coil's so I will link you to the kicker wiring guide...

http://kicker.com/sites/default/files/SoloBaricL72006.pdf 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

Its better and cheaper to replace the speakers.

check to make sure your box is securely sealed and that the box itself is not rattling. if not, most subs require a break in period where they can not be played full gain/full volume for the first 48 or so hours... did you break in your subs by paying it softly the first day and slowly turning your amps gain and receivers volume up the next couple of days. if not, it is likely blown

This will help you :)


Below is a link to the subwoofers manual where is clearly states how to wire it all up, it includes both the 2ohm DVC and 4 ohm DVC models.

check the wire inside of the sub box

Hi yeahonda,

 

Your Kicker L7 Ohms may be too low for the MA Audio Mono block amp. The MA Audio Amp is probably 2 Ohm Stable. The kicker will either be 2 ohm or 4 ohm Dual voice coil.   To eliminate the low ohms as a possible threat to causing the map to go into Protect, Wire the kicker Voice Coils in Series.  This adds the ohms, so that you either have 4 or 8 ohms. 

I am using the following codes to show wiring. VC1+ stands for the Kicker  Subs Voice Coil #1 Postive post. AO+ is the MA audio Amp output positive.

 

AO+ to VC1+

VC1- to VC2+

VC2- to AO-

 

This shopuld give you 4 or 8 ohm depending on the 15" L7 setup.  Crutchfield does not carry the Kicker  L7 in 15" They do  have the L5 in 15".

 

If you know how to read a Volt Ohm Meter, set it to OHMs 20 and measure across VC1+ to VC1- and you should see between 1.5 and 5 ohms..  Do the Same with VC2+ to VC2-.  you should see the same voltage. Also read from the Voice coil metal housing to VC1+ , VC1-, VC2+, and VC2-. and you should not read any ohmage to the case. The meter should say OL, or -1.

Good luck.
