My friend borrowed my car one day and apparently turned the volume super loud. When I got the car, my head unit wouldn't even power on. I don't know what to do. Someone suggested checking the fuse in the back of the radio, and I will certainly do that, but are there any more suggestions? The head unit is practically brand new. Thanks for any advice.

check the fuse, then come back and tell us if that worked

^yep. check the the radio fuse(s) on the vehicle first (you can locate it in your owner's manual), then the one on the back of the unit or inline on the power wire.

In that case, kick him in the vagina.

ok, reporting back live -- the fuse in the back of the unit is not blown. i also checked the fuse in the box and that has not blown either. next step guys? i would be willing to pay for someone to take a look at it if they had some time on their hands -- i needs mah musics, NOW!

you could take a multimeter to your outputs and determine if it's the head unit vs amp/speakers and repeat the process at the amp. both of those are going to require taking some things apart.

Use a multimeter to find out if the power wires are supplying power to the head unit. There should be a yellow one and a red one. Both should have power when the ignition is on. If not then you have a wiring issue. If they both have power then your head unit is the problem. There's not a whole lot you can do aside from unplugging it and smacking it around.

There should not be a volume level that kills your head unit, so it's pretty likely that it was just a bad one that was going to fail eventually anyway. You say it's pretty new, so maybe you can warranty it if it is in fact dead.

try pushing the reset button. if the face is detachable it should be behind there. if not, it should be on the faceplate somewhere. it's a small button about the size of the tip on a ball-point pen.

alright, i will def try the reset button. i do not have a multimeter though, is there anywhere I can go that will do it for a small fee or for free? thanks for all of the advice thus far people.

I'm going to guess no on that. A digital multimeter can be had for cheap at your local hardware store and will do what you need it to do.

Also, double check those fuses for continuity with the multimeter. Sometimes (rarely) card-style fuses can fail in such a way that at first glance they appear to be OK. Just double check, or replace with new fuses since it's easy.

Thank you guys for all of the help. Had a friend take a look at it - had no idea he knew about electronics as much as he did. come to find out, there was some fuse blown that I didnt even know existed. It wasn't in the radio, but some other fuse in located in the wiring behind the unit.
