just installed a china made double din from ebay.. after the 4 hour install I went to a friend's house for no more than an hour or so.. came out car wouldn't start... I had my amp and subs hooked up.. they were hooked up before i got the navi installed. it never did it.. the day i get it installed it doesn't start.. any ideas? has this ever happened?
 
Is it holding a charge now? .... Probably just drained it too much during the install.....
 
Test your battery with a multimeter and see what your draw is with the car turned off. Sounds as if there is a wiring issue with the stereo. Also, where is the ground located for the amplifier and did you use a wiring harness or split in on your own?
 
A battery should not drain so quickly especially if I am reading the op correctly in that he drove the car after installing(especially).
 
I know this is the dumb question but did you wire it correctly as in the ignition only only power (usually yellow) is not to an always on power source. That is the only thing I could think of that would cause draw or possibly the remote wire is constantly on, not switching off with the unit, there fore letting the amp run constantly .

I would charge the battery then leave the car off and see if you are getting voltage from the remote wire or at the amp any where.
 
Question 1 is... is it still dead, is it holding a charge as of right now...
 
I put a volt meter to my battery.. off it reads 12.3 on it reads 13.8 fine.. the guy that installed it is saying that he's a professional and he promises me that he did it right.. i said take it out so i'm going to get it taken out.. see if that's it.. if it's not it than i'll know it's something else.. but i'm hoping that as he's taking it out he will notice he flaw'd on installing it correctly.
 
it was dead last night as i came out of my friends.. it was dead.. i boosted it drove it home parked it this morning it was really dead like nothing not even click of the ignition. i boosted it.. it's only been an hour or so.. im not gunna check now but im supposed to bring it back to get him to take it out.. so when i go to start it for then we will see.

I did infact use a wiring harness.

I would also like to state when the car was entirely off. I tried to turn the navi on.. it wouldn't turn on.. so idk if it was on constant power why it wouldn't turn on.
 
That is a such a very quick amount of time to draw a battery down. Use the multimeter and see what you are drawing off of the battery while at rest.
 
It died again.. my terminals were loose.. thought it was that.. it wasn't.. so somethings drawing power.. and i used a volt meter today battery read 13.8 on and 12.4 off.
 
Have you changed anything with the amp remote turn on? Was it rewired to the new double din or has that not changed? Is the amp turning off when the car is shut off?
 
Here is a simple test, disconnect the power wire for the amp from the battery. If your car starts in the morning, feel free to have your stereo guy go over his work. Be sure to tape the power wire off so it does not accidentally touch the battery terminals. If it still does not work, the battery is done, at the least, and your alternator may be the main culprit.
 
i would unplug the remote wire on the amp not the power wire, the remote wire is the one being sent from the unit (blue and thin most cases)

if the car starts after sitting then something is wired wrong on the back of the HU

on some cars there is a factory amp, sometimes you have to apply power to this oem amp to get sound, if he wired constant power to it then the battery would drain as well
 
+1 with 250.

I thought about saying the remote also but if it was truly professionally done, disconnecting at the battery would be the quickest and perhaps the most easily accesible if you are not well versed with the amp's wiring.
 
Thats not it. The amp isnt even in the car and the batterys new cant see how it could be bad the volts read proper for off and on..
 
Your op said you had your amp and subs wired up. Heads up for the next time you have a question, please give very accurate descriptions of steps you have taken. It will make it much easier to get an opinion/answer.
 
Okay okay sorry.. My amp was hooked up.. Now it's not..

And actually it says "they were" hooked up.

Something is hooked up wrong because there's a circuit that shuts off all power to everything else after 30 minutes.
 
Not to be harsh, but I am going to be candid. Since you want to split hairs over verbiage, the word "were", as you used it in your op, may infer to some readers(it did to this one) that your complete stereo was instyalled when the issue occured. If the amp had nothing to do with the possibility of issues, there was really no need to mention that your amp and subs were "hooked" up. That clarification was due much earlier. With that being said, I think the amp was, and is, in the car and you do not want to acknowledge that your "stereo" guy(actually being you) either made a wiring error, or that you have a defective amp.

With that being said, I wish you the best with your issue. Split hairs with another with another member only trying to help.
 
Buddy. My subs and amp havent been hooked up since that day.. my buddy conrad did it.. i dont know the first thing about car electrical. I apologize for the confusion. But i wouldnt lie on a forum saying my amps not in there and it is? Im not gunna get the right help.. THAT BEING SAID i think i narrowed it down to be not so much the deck but possibly bat alt.. or bad battery.QUOTE=marcredd;896537]Not to be harsh, but I am going to be candid.

just throwing this one out there, there may be an internal problem with the radio, and it is eating up power. wouldnt be the first time somebody sold a broke @ss radio on ebay.

use a meter and watch the current being used by the radio while off, also at the battery with the radio connected and disconnected.

some one would have to be an idiot to screw up the install when using harnesses, like hook up one of the blue or blue/white wires to the cars yellow, and thats about it.
