So, about a couple months ago, my entire stereo went out. The Dash/headunit and everything powers up, but there was NO sound; on top of that, the car lighter in the elbow console did not work either. As a result, I thought I had just blown a fuse. Since I do not use the stereo much, I was just too lazy to check all fuses, and just left it as is.

Well, on a whim, I tried out the stereo yesterday, and all of a sudden, the sound came back! It's as if nothing was ever wrong to begin with!!!

This gets me thinking... since the stereo/speakers work now, I'm assuming it wasn't a fuse problem. Any thoughts on this?

I wish I could provide more details, but this is as detailed as it gets. Thanks in advance for your input/advice!

Any long cranks on starting
If the car detects a low battery condition it has the ability to
shut stuff down to conserve battery capacity and keep the car going.
What it does and it what order I don't know.

I would measure your battery with a voltmeter
or have it tested.

Other thinks might be the amp overheats or loose cabling.

Cranks are spot on, no issues there.

As for the amp overheating -- i'm not sure that'll be an issue because I don't listen to my stereo very loudly. Also, for about 2 months straight, even upon start-up, the stereo would turn on, but the speakers didn't work. If it's loose cabling, that's going to be a HUGE PITA because I wouldn't know where to start.

As of now, the stereo works fine... it's been working fine for 3 days now. I'm not sure what it could've been -- but it's driving me nuts. I just hope it's not anything serious.

Happy Pre-Turkey day everyone!

Its in the Trunk in the area between the wheel well and corner.
Visual inspection is a first step in any troubleshooting situation.
The next would to get a code readout on the car.

Thanks for the heads up guys, really appreciate the help. I wish I knew what those diagrams were, but i'll try to fiddle with it... need to learn somewhere right? and i'm sure those diagrams will surely come in handy.
