Subwoofer i have a kicker L7 15inch woofer..im trying to wire it up in my box and amp..i already have a woofer in there but i cannot get the woofer to work..i looked at the wiring that crutchfield had said but it will not work...i have a MA audio 1000watt mono block amp.. when i wire it up the protect light comes on in my amp..is the sub just blown?

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.
