Default Car off - Amp still draws power. Plz Help...

I just found out that's what was killing my battery almost daily.

I checked the amp wiring - Everything seems to be in order.

Remote wire works. Amp power led lights up when car starts. Light goes out when car shuts off. But it continues to sap power for some reason.

The ground was on painted metal. I scraped the paint and connector, then reattached the ground. Power drain is still present.



Is there a product that can block the amp from the battery until the car has been started?

That's what your remote wire does. I wonder if your amp is malfunctioning IF you are sure you connected the remote wire correctly.

It's possible. I've heard some amps have that problem. RE The remote wire being connected properly: I couldn't say for sure. I had it installed at a stereo/alarm shop.

The remote wire SHOULD be connected behind the cd player to a blue wire. What cd player make/nodel do you have?

with a simple 12volt light tester or multimeter check the remote turn on wire and see if it has power when the car is off.... if so your remote wire is not hooked up correctly... just because a stereo shop did it doesnt mean they did right... small shops are lazy as hell! they could have easily ran the wires and shorted the remote wire onto the power wire somewhere under a trim panel cuting the two wires.....


but if you really want your amplifiers power wire killed then go buy a solenoid any auto shop will have them. i know they use them on fords around the 80s.....

or try a audio shop for them....
heres a example...

but they are out of stock right now..... you wire that up next to the battery AFTER the main fuse and run a small remote wire either off the radios remote turn on wire OR just to the ignitions ACC position..... either will work fine. BUT if your remote wire is still geting power then something is either BAD or shorted on some metal somewhere....

easiest way for you is go back to stereo shop and complain your @SS OFF!!!!!!!! and make them fix it free of charge!

Disconnect the remote wire entirely at the amp. Then if it's still drawing power the amp is defective.

The head unit is a Sony. I forget the model number, but it's the one with the flip-down screen that goes stealth black when the car is turned off (the MP3 version). I checked the blue remote wire. It's connected where it should be on the HU.

Bingo! Disconnected and still drawing power. I guess I have one of those faulty amps that was mentioned earlier. Other than murdering batteries it works great.

addiction2bass...Thanks for the link. I'll be getting me a relay soon. And thanks for all the help, fellas.

ya thats why these small shops are not worth saving cash by using... they all go under so quick or they SUPOSEDLY have a new owner and change there name so any old warentes they might have SAID are good are GONE...
ill stick with ebay or direct sellers ratings on ebay are harder to get higher. the higher the better seller.
