Question about MA Audio M1900XE Car Amp
I actually have ma audio m700xe but this was the closest one i can find to it.
i have a 1000watt ma audio amp and a 300watt spx amp and at first i just had the 1000 watt amp hooked up to two 12 inch subs idk what watts but its the pair that come with the amp ma subs.
and when it was by itsel it was extremely loud i had to keep the bass db in the car on -10 i got a splitter for the wire from the power to the battery to hook the other 300 amp up for the door speakers
after i got it all hooked up the bass was no where near as loud if it was on 0db it still wasnt as loud as it used to be on -10
so i hooked everything up like it originally was and it never got as good as it was also i noticed the 300 watt subs sounded better hooked to the subs so i hooked the 1000 watt to the doors and tweeters
then today, four months later i was driving and i all of a sudden the doors went out and all i could hear were the subs i thought it was a bad ground but when i changed the song it would play fine then smoke started coming from my back seat and trunk i got home and checked it everything looked fine
but now my ma amp will not show any signs of power, power light or protection light and my spx amps power will not turn on but when i disconnect the ground the protection light comes on other than the protection light no other signs of power and nothing is coming out of any speakers
grounds ar good the big fuse 6 in away from the battery is good and the 25 fuses in the amps are all fine
This is caused by inproper wiring from the speakers/subs to the amplifier.. an amp will still put out power to subs and speakers when it's wired improperly but it won't last for very long doing it... 6 months is longer than usual....

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.
