Melted voice coil? Short circuited voice coil due to overload? does your amplifier work properly? Is the (-) properly grounded? If the SUB is in working condition and there is nothing wrong with the amplifier. 1) The amp is not powerful enough to run the sub 2) The amp is not properly grounded or powered 3) Remote Sensor wire is not connected 4) RCA Cables or Hi - input sensors are not connected Check out the installation to verify or the sub may be damaged
You can not connect the subwoofer directly to your head unit. You need an amplifier installed to play the sub woofer. Asuming that there is an amplifier installed then:
If your head unit has an RCA output on the rear, connect that to the LINE IN of your amplifier.
Also there should be a Blue&White cable at the rear of the head unit.(amplifier remote) That should be connected the the remote terminal on the amplifier. (this will turn the amp on and off when the head unit turns on or off)
Hope this helps.
power wire from batt fused to positive on amp .earth wire eg - to bare
metal in car with bolt or screw. remote wire from amp to remote wire on
back of head unit mostly blue wire it tells amp when to turn on then
you need a set of rca cables to send sound from head unit to amp they
go in subout if you wanna use sub or rear or front out for full sound
best thing is to buy amp kit cheaper most the time and all you need
there hope this helps

The cable should not cause the problem unless it is shorting out somewhere on the remote or positive cable. I would use a larger gauge wire first as this is the cheaper way to go, and if the same problem occurs you are having a short in the sub or box causing the protection mode. You will have to back trace to find possible cross connections.
first of all is the amp a four way amp? if so then you need to know what the watts of the subs are (you dont want to melt them) wire + and - of channels 1 and 2 to one sub and + and - of channel 3 and 4 to second sub, nice thick lead from battery positive (fused) to positive terminal on amp thick lead from a good earth point to negative terminal on amp run a set of rca leads down the opposte side to the positive wire to prevent interference, run thin wire from remote wire of radio to the remote terminal of amp, rca's are plugged in at stereo and at the am. may need a RCA splitter to be able to power all four channels
Does it happen at all volume levels?
What is the gain setting on the sub amp?
Have you checked for 12V @ remote turn on after problem occurs?
Sounds as if the remote turn on relay inside the amplifier is losing signal, or has become damaged. If the protection light does not light up, the problem is not thermal, shorting, or high/low voltage.
The amplifier is in need of repair. This is not an end-user fix. Looking at about $50 to repair.
Thanks for using FixYa- a FixYa rating is appreciated!!
i have the same amp and have that same issue before. yes you are correct that if you take off the RCA cables on the input there will be no light. either you have plug the remote line on the 12v or a grounded sub. it should be 12v/remote/ground from the corner. good thing im just fixing my sub earlier. it is no problem if you have hooked the remote line on the 12v, it is the same supposed to be. to check if your amp is working, short the 12v/ and the remote line and play your stereo and see if your sub is working. by the way, what sub are you using? i just blew my sub and need a new one.
