Question about Kicker Solo-Baric L7 S15L72 Car Subwoofer
I have a brand new 4 ohm 15 inch L7 that i hooked up yesterday i have it running through a kicker zx1500.1 at 2 ohms. when i play it the subwoofer i hear a faint rattling noice coming from the sub. nothing is inside the box it is coming directly from the sub... is it a blown voice coil??
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

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.
