I've had the amp for a lil over a year now n had it hooked up to two 10" subs. I just got 2 12" subs but when i turn on the car the speakers make a pop sound and the lil red triangle lights up for a couple of seconds then turns off. The fan on the amp still blows but there's no light n the subs aren't working. When i was taking the amp off the old speaker box the power cable came undone and when i went to screw it back in, it hit the side of the amp a couple of times n just made a lil spark, nothing major at all. Stupid me forgot to unplug it from the battery DOH. figured my car was turned off soo i'll just screw it back in. But i didn't think the cable taping the outside of the amp would effect it. I checked the fuse in the amp and in the cable n they look fine.

Ok, for starters. Is your sub a dual 4 ohm sub? If so, great. Is your amp 2ohm stable? If so, then great. If you are running one sub, is your amp a monoblock (single channel) amp? Are you running a two channel amp Your subwoofer is a dual voice coil subwoofer. This means that you have to have power to both voicecoils or risk damaging the voice coils. Subs are designed with dual voice coils to give it more control over the cone movement. This results in better reproduction of sound. Anyway, back to wiring.
This is for a monoblock amp (you can also bridge a 2 channel amp) Go from the positive speaker out of your amp to the positive posts of both voice coils. Then go from the negative speaker out of the amp to both negative posts on the sub. And there you have it. It's called a parallel set up. Setting it up this way just dropped the ohms load for that sub to 2 ohms. Less resistance means more power to the sub. Hope this helps
Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.
if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,
ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...
this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,
this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil
if your need more help give me your email and ill send you a pic of how to do it...
first check that the subwoofer function on the actual head unit is turned up,second check that the gain on the amp is at bout half way then check that it is on a lp (low pass setting)
then check that the boost on the amp is turned up.
please leave feedback.
Humm.. Have you check your remote wire? If you know the amp is getting power for sure, diconnect your subs from the amp leave only the + - and remote hooked up. Check again if still same thing nothing, try taking a jumper wire to the batt terminal over to the remote terminal. This should let your amp kick on, IF SO your remote wire has a short some where. IF NO i would check your ground wire again and make sure its good and along with all your fuses. IF NO still might have internal damage. BUT if it did work dont leave it hooked up like that, it WILL stay on untill u remove the jumper wire. I just use this lil trick to help save time with trouble shooting. Hope this was helpful i had the same prob with my amp remote wire was bad
