Question about Car Speakers & Subwoofers
I purchased from Crutchfield a Kicker CVR 15" set of Subs about 4 months ago. Since having it I have experienced problems such as a rattling noise when playing. After taking it to an Audio/sterio store they informed me that it was the 2nd voice coil and it was blown because of a wire that had snapped and shorted it out. I can't find the warranty information and was wanting to know what process I should take in returning the damaged unit to have it replaced. Please let me know how to handle this problem.
Have you called crutchfield yet? The are pretty good with customer service and stand behind their company. If they protest, get loud, they will likely bend. I have dealt w/them for years.

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.
