Re: Kicker L7 Repair

With the price of speakers dropping all the time it's really not worth repairing as it will cost too much to have it fixed by hand.

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.

My 2006 12" L7 kicker sub isn't working like it should. It simply sounds like an extra speaker and produces minimal bass. All the wires are correct, I have checked and rewired it several times just to make...

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.

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.

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.
