earlier today my friend tried to install my amp together, but he put the wire connected to the battery where you are supposed to put the ground wire and the ground wire where you are supposed to put the battery wire while the car was on. and now my head unit wont turn on. could you help me out and tell me whats wrong and how could i fix it.

 

def check your fuses and your connections. but i dont see why that would affect your deck too if its just your amp. and dont forget depending what deck you have, there might be an inline fuse on it as well.

 

i tried to check the fuses but they i didnt know which one to check and got confused.

 

The ones on your amp and the ones under the dash board.

 

Most amps only fuse the (+) input, so there's a good possibility he smoked your amp.

 

Most amplifiers don't provide protection for this "installation error". I'll bet your amplifier's toast. Check the fuse on the amplifier, and if it IS blown, replace it, but watch for the fuse to blow immediately. If this occurs, DO NOT add a larger fuse, and try again...the amplifier's power supply is fried, and the amplifier will need to be repaired/replaced.

 

i figured the amp is blown but now im worried about my head unit . when i disconnected the amp my head unit wont turn on.

 

check your connections on the back, something could be loose. and check the fuses under the steering wheel to make sure that you didnt blow the one with the stereo. but other than that, i dont see why your amp would affect it.

 

that sux u shouldnt play with power wires while ur car is on. but good luck

 

As an answer to your question, check your fuses in your car. There should be a panel that has a diagram of which fuse to check. It will say acc or radio or something to that effect. If you dont know which one to check, check them all, it wont hurt. If you find a burnt fuse be sure to replace it with the SAME AMP fuse never a bigger one!

Second as somebody did mention, check your fuse in the back of your stereo. You may have one you may not, but most newer stereos do come fused in the back.

If all the fuses check out, then check out the wires in the back of the stereo. It could be possible since you switched polarity that a non fused wire became fried. First look back behind the stereo then as weird as it sounds smell back there. If its a fired wire the nasty smell will linger for a long time.

If you have any other questions please feel free to e-mail me or pm me.

thanks for all the info everybody ill check it out asap.

 

i just check out the fuses in my car and the one that says rad was blown and luckily the amp survived.

 

Now you smack your friend if he even looks at you stereo the wrong way. And tell him his installation privileges have been revoked.

 

i didnt smack him instead i kicked him in the jewels and put a sleeper on him and when you was knocked out i started kicking him some more
