Check for dc or clipping in your amplifier.distortion causes a dc component which will burn out the voice coil.if you take a 200 watt woofer and run a 20 watt amp at 20%distortion,the dc can cook the voice coil.

I have 2 MA Audio HK 15 X 2 subs and voice coils are blown. How do I fix them


There is little chance that you can do anything about it. The exact voice coil would have to be identified, the old ones taken out, and replacing them is technically difficult/impossible without the proper tools and experience.

Need to know how to repair my voicecoils


If you have removable voice coils, you can take them off and buy new ones, otherwise, the speaker is pretty much hosed. Voice coils require too much precision to be made by hand.

that subwoofer has dual 4ohm voice coils, if your amp can handle 2 ohms, you would put a wire from the positive (+) on the amp to the positive on both connectors on the sub, then hook the negative (-) on the amp to the negative on both the sub connectors that will be a 2 ohm load on your amp make sure your amp at 2 ohms is not more than 600 watts RMS or 1200 max.

How should I wire my 3 subs to the 500/1 amp???????


First of all how many ohm's are each subwoofer rated at . Are the subwoofers dual voice coil or single voice coil. Once I know that I can help you. I think the JL amp is not recommended below a 2ohm load.

Make sure that you have the subs wired in a 4-ohm series and not a 8-ohm load

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.

Repetitive buzzing noise


Some componet in the Amp circuit is breaking down. The longer you let this go, the more of a chance that you will have a major short and blow out several parts,m as thats what happens with amps. Get it service asap and dont use it.
