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?

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

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

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.

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! :)

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.

ROFL, leave it to haemphy to roll in pulling the classification badge in 1 hand and a six-shooter in the other... haem, Im sure the guy means well and is just trying to help, perhaps you can re-word things a little? I dunno maybe Im sensitive. Idiot name change, reason #234!

He's been here one day... He's posted 34 posts (as of 0549 this morning, and 24 of those were since 0100 California time last night). Twenty of them made little to no sense at all, and the other 14 made even less sense or were completely wrong... Meaning well and DOING well are two very different goals, and this guy *IS* the "Bad Advice Monster" that tcss has threaded about, and the same guy that nearly all of us here at the12volt are trying to thwart.
Take this one for example:

Now, is this even REMOTELY correct information? I thought I *WAS* being nice. ------------- 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."

Yikes! nokie1, please listen to "i am an idiot'" and ignore tjjr8120. tjjr8120, I appreciate your participation, but you're simply too dangerous and uninformed to be offering advice to anyone on this forum at this time. -------------  the12volt • Support the12volt.com

I think another "WOW" is appropriate here... Do you think we pushed a button?
tjjr8120, I can guarantee you that i am an idiot IS a troubleshooter. His 5800 posts have EVERY ONE been helpful in some way or another, and I have read every thread in which he has posted. I have watched him help people half-way across the country repair dead amplifers without even seeing pictures. This guy is a better tech than any I have ever seen, and if I ever need any kind of repair on pretty much ANY electronic device (I admit that I am NOT a troubleshooter) it's getting shipped to this guy.
While you might be a fantastic fabber, and your installs migh be superlative in their execution, it DOES seem you have trouble putting into words the proper method of "fixing", or "implementing". I know it's easy to be all gung-ho when you join a new forum, but you really should hang out and read a few posts from some of the members with higher post counts. The reason they have those counts is because they KNOW WHAT THEY ARE TALKING ABOUT!
So far, your information has been all over the board, from OK, to downright dangerous - a voice coil oustide of a woofer? Running that kind of power to it, it's GOING to get hot... VERY hot. This is dangerous. This is what we are getting on you about. Please be more careful in your suggestions, and spend a little time formulating your answers as well as entering them. Additionally, this is a web forum, not your cell phone. Texting 1337 is COMPLETELY unnecessary here, you have as much space as necessary to post. With the use of proper punctuation and grammar, people will likely think more of your responses.

You are not helping people, so "stopping" is not really an option. The PM you just sent to me... tjjr8120 wrote:

0 gauge in the car audio world is known as hot gauge lol but 4 gauge is around 80-150 amps
2 gauge 150-250 amps
hot gauge 250-300 amps
sorry 350 amp fuses don't exist unless you make a special order.
But since your amp is using a 70 amp fuse you will be ok with a 150-200 amp fuse.
tjjr8120, you proved my point. ------------- the12volt • Support the12volt.com

Yeah somethings he states might be wrong butvI don't see anything wrong with this post right here. All he is trying to do is see if the remote wire from the radio is working right. I do this all the time on bench testing or even when you don't have a remote wire and us a switch. I just thank people are mad at him because the might or might not do this for a living and because he is not high level like a few of us that he can not try to help out that is what the forum is about or is it not. So now there is a rule the people under so many stars can answer to post now. That is wrong, Not stating that everyone is right or wrong just people that different was of doing things. This is what the forum is about learning from other people that have done it and people that want to learn how to do it. But since people have a high star or stat that means someone can't be better then them at things. What is the world coming to.

There is no rule as you have suggested and it has never been implied. We are all here to share our knowledge and learn. Post counts do not indicate anything other than a member's participation. Post counts do not indicate any member being better at somethng than another. It is the content of the member's posts that can indicate what they do and do not know on a given topic. Stating fiction as fact can be dangerous. When it is, it is not something this site supports. Add flaming PM's and posts to the mix and the member is done. ------------- the12volt • Support the12volt.com

Vibration, this post really does have only a little to do with the larger picture. It just happened to be where the issue was addressed.
