I live in an apartment complex and last night when I was parking my car I went over the speed bumb a little fast, Well when I park I have the stereo off. Today when I got in the car my I didnt hear my subs so I looked in the trunk and checked the connections everything looked fine but still no power was going to my subs. Is it possable the 12v wire to the battery fell off or something?? What else could it be. I dont know the first thing about this sh*t so please bear with me

Thanks

Nicole

Well I will give you a place to start...when you have something like that you just hope that it is a fuse..sometimes it could something more. If the 12v wire or ground was loose on your amp..it could of wiggled and caused a fuse to blow. Check these fuses:

Fuses in your amp...Battery terminal fuse(on your power wires).

You also may want to grab a DMM and see if your wires are still connected to the source they are suppose to be meaning...if you have a ground..and you see it in the amp.. make sure that wire is still grounded.

yes make sure your ground wire is secured tightly to a good metal surface, preferably with a star washer. The star washer digs into the metal a little bit so you get a good ground. Make sure the place where your amp is grounded is clean(no rust or anything) and that there isnt any paint on it either. Also make sure, of course that the screw holding it down is secure. I have seen Best Buy installs where they just taped the wire to the metal or something like that. Also does your amp turn on still. If it dosnt make sure the turn on lead is getting power from your head-unit and that it is securely on the amps turn on lead terminal.

Ok Thanks again for your help. It took me forever to figure this out but I found other info. I looked to see if the 12V fell off the battery but no luck then as I was looking for where the hell this wire could be I found It I guess its on the alternator......What the hell is it doing there I thought it goes on the +battery??? Like I said I dont know the first thing about this stuff, What do I do take out the wire from the alternator and run a new wire from the +battery to the trunk?? Again I Thank You SO Much

You see to know more than you think you know as you mention alternator... So the good news is you will get this to work if not already. As the previous people have mentionned, you have to check if you are getting power first. It could also be possible that the speaker connections got loose or came out as well. If your speaker connections are ok, then it has to be power or maybe even the "remote" wire. Many amps have a remote wire connected to the head unit, that turns your amp on when you power on the head unit. If that wire came off, it will not work either. So check power, then remote-wire (might be a thin blue wire), and speaker connections.
