Already did the big 3. I get serious voltage drop im talking from 14v drops to 10v. Then after I play a song or burp, my batt goes from charging @ 14v+ to charging to 12v plus my amps are regulated so that dont help at all. But im also thinking my alt could be bad because shouldnt the alt charge @ 14+volts no matter how low the battery is? But if I disconnect the batt while the car is running the motor stays running so IDK..
