I have 2 12" solo-baric l7s but don't know what

Get a dual vented box for them. Not some cheap stuff either or it wont last. Then make sure theyre facing the back when you hook them up. I know its weird but they hit WAY harder that way trust me.

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

Wireing two dual 4 ohm kicker cvr 15s on a memphis pr1000 at a 1 ohm load. I trying to get these kickers to hit harder. Do I need a bigger amp or what?

CVR series do not have large power handling capabilities.
Your subs will melt before the amplifier is used to its full potential.
If the subs arent in a ported enclosure - do that.
They both handle 500w rms - so the pr1000 is perfect.
bass response is all in the enclosure!

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.
