wow never heard of that b4. did u try to isolate the problem? remove fuse to the amp. and see if it continues to shut off.

 

who checked your alternator? are you sure they really checked it?

 

yep alternator was checked out by autozone and KRAGEn...both said they were fine....yes i tried removing the fuse...and restarting the car..but the car wouldnt even start...I mean the entire battery was drained...!..nothin worked in the car........this is how i wired up the amp


Battery-----{Fuse}-----------AMP---------tapped into wires from sc400 sub amp(input)
+
Made my own toggle switch for the remote


on the amp the gain is only at half way....WHAT is GOING ON PLS HELP!

 

sounds to me that the alternator isn't charging the battery ....

 

Toggle switch . . . hmmm . . . do you remember to turn it off every time you exit the vehicle? Most times, you want to run a remote wire (with relay) from the stereo to trigger the amp's power. A few times forgetting to switch it off by a toggle and VOILA! Dead battery.

With an amp that draws that much current, get a sealed battery with at least 800cca and connect at least 2 farads of stiffening cap for the spikes in current caused by bass notes . . . That should eliminate any lackluster performance (music) and alleviate any type of power issues within your interior lighting / headlights (dimming on each powerful note).

Hope that helps.
