Know how to use a multimeter? You have a draw somewhere.

 

yes i do thats my next step after i install a voltage stabilizer anyone have one installed???

 

how old is your battery?

 

Its brand new!!!
Lest than a month

 

do you have your deck wired so it will only come on when the ignition is on? imo it seems that the deck is still drawing power from the battery somehow.

 

well if you are trying to run a sound system that has too much wattage for that battery and you keep killing them then you should probably run 2 batteries. (to be on the safe side)

 

why is your stereo hooked up super ghetto like? your amp is supposed to be hooked up to the remote turn on on your deck so it only turns on when the stereo is turned on. and your stereo is supposed to have two power sources going to it. a constant power to keep the clock and presets and settings saved, and a "switched" wire from the ignition so your radio isn't constantly drawing power.

that said, make sure that the power wire isn't accidentally hitting the remote terminal, i had that happen once, one or two strands from my power wire didn't go into the amp and were touching the remote terminal causing the amp to always stay on.

 

thanks for heads up dude but update i rewired everything yesterday added new grounds check my charging system and my problem is fixed atlease i hope so imma give it a trail period to really say its fix but my battery isnt dying anymore and i've gained power in acceleration...
