Hey guys, it pains me to say i've blown one of my subs. Now i've put a lot of thought into my current setup and i'm having trouble deciphering my issues. For anyone to help ur gonna need an equipment list so here goes:
headunit: eclipse cd 7100
Vehicle. Cavalier 2004
wiring: cadence 1/0 to 2nd batt and sub amp, cadence 4 gauge to speaker amp.
alternator EA 350 amp ho custom.
big 3 in 1/0 done.
Batteries: up front stock, rear optima yellowtop ran in parallel.
Sub amp: ma audio hk602sx
speaker amp: ma audio m489I
Subs: 12" dayton audio ho dvc 4ohm
Front speakers: clarion srp4620m
rear speakers: eclipse 6900
all speakers/subs run on individual channels at 2ohms.
gains set using digital mm subs at 700wrms 37.6 I believe volts output. Speakers I don't remember but it should be at rms rating.
Now my subs could handle everything great except the voice coils burned while listening to lower rap ie. Gorilla zoe/ little wayne/ 36 mafia stuff like that. I had some headlight dimming but I figure those are so sensitive to voltage drop ur always gonna get a little. On the voltage meter at the rear battery voltage never dropped below 13volts. Even on rap. So my only guess is im getting clipping from something but I just don't know what to fix........the subs always soundes extremely accurate.
The enclosure is a dual band pass folded horn design from decware called the wicked one. Now that design the subs do sit in a sealed chamber so they will get hot, but I never figured I'd have issues with these setup... how do I fix this so when I replace the subs I wont just fry the next one?
