amplifier not coming on when car starts

i have a sony amp installed and when i turn the key to "acc" it comes on but when i start the car it doesnt come on.  when i first installed it the amp was just fine, also when the car is started the amp light will blink sometime. what could be the problem?  thanks

Using a volt meter, what is the voltage on the remote wire of the amp?  First with the engine off, then with the motor running.  Is it an older GM Vehicle?  Do you have a High Output alternator?Let's Go Brandon Brown. Congratulations on your first Xfinity Series Win. LGBFJB

waht type of vehicle? if your remote start isn't tied into the acc circuit, then it won't turn on until key take over is done. otherwise you can relay an addtional feed to the acc circiut of vehicle to resolve this problem " I see wire diagrahms "18 yrs+ of installing - not good on the brains LOL

My mistake read the topic wrong, you may also use a relay to fire up the remote line via acc. sorry for the misread" I see wire diagrahms "18 yrs+ of installing - not good on the brains LOL

its an 82 olds delta 88 with a regular alternator.

The voltage regulator in those vehicles are notorious for failing.  When they fail, they will put out upwards of 15 volts.  If the amplifier sees too much voltage on the remote wire, it may not come on.  It does this to protect itself from burning up from overvoltage.   Do your headlights get just a little bit brighter when you start the engine?  Or do they get much brighter.  The meter readings would help more.  But if you have no meter, the headlight info will help.  Do you live near an AutoZone?  They will check it for you for free.  If you do go to get it checked, tell them you think the regulator has failed.  They may not check for too much voltage unless you specify that problem.Let's Go Brandon Brown.

Dude... you are SERIOUSLY outclassed here... Maybe you should just let i am an idiot handle this one...It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

After seeing some of the absolute freakin' MAGIC I've seen you perform here... If someone told me to listen to the idiot, I'd be listening! :)It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

But wait, DYohn and I were just wizing "Quoted, I didn't misspell it" in diapers when this impressive database of knowledge began.  I bet Microsoft Access was used to create it.  I seem to remember the time even before Microsoft.  So I know I remember when they introduced Access.    DYohn or Admin, please let me know about my signature line.Let's Go Brandon Brown.
