[QUOTE=userfriendly;819585]Ano ba ang problem? Can you list your system? Does your amp cut off when you play at loud volume for a long time? If it does, your amp might be going into protect mode. This happens when your amp starts to overheat. Easy solution is to make sure your amps have good airflow. Make sure heatsinks are not dirty or blocked. Also never mount amps upsidedown. You can also add cooling fans or lower your volume.

If that is not the problem, try adding a capacitor. It will give your alternator time to catch up.

tama rin c userfriendly, baka nagooverheat amp mo.. san ba nakamount ung amp? try mo maglagay ng spacer between nung base ng ampli tsaka ung mounting surface. this way, may papasok na hangin sa base ng amp that will help to cool it down.. and try to mount it vertically para mas madali syang lumamig.
Mga bosing salamat sa reply, anyways, eto ung issue, not really familiar with the way an amp "cuts off".

While playing loud, after mga 45 mins., ung tunog anjan parin, pero parang sa likod na lang nanggagaling, wala na sa front speakers ko, tweeters, at ung bayo ng sub significantly humina. Maya-maya, after 10 mins. or so na i-off ung sounds, pagkaon mo balik na uli sa dati, pero after mga 45 mins. uli na malakas ang patugtog, ganun na naman.

Ung mounting ng amp ko is sa likod ng box ng sub. Bali nakaharap sya vertically sa rear seats ko, may around 2 inches allowance un from the back of the seats.

May capacitor na rin akong nakalagay, and setup ko e targa x652c (tama ba?) front, stock rear, aura sub, at v12 4 channel na class A(cant remember the model).

Tried scouting for the alternator kasi, wala talaga. Kahit sa mga online shops like ebay wala for my car. Kaya ako napatanong sa baterya, kung oks ba na magpalagay ako ng secondary or useless din at pagafter ng 45 minutes e gaganun din ung tunog?
