Sony XK-R100 car audio preamp troubles

My Sony preamp started acting funny awhile ago, would turn off by itself after I would turn it on. It didn't matter if I was listening to a cd or the radio, the result would be the same. It was installed in a BMW325 with external amp and eq....have replaced with old Blaupunkd which works just fine so I've eliminated my wiring job as a possible culprit. Have searched google and there seems to be a site called Euras (?) that will give out info but you need to be an organization...they list a possible problem with the faceplate and bad onoff button...can you enlighten me? Don't want to trash player cause I've had it since new/great shape, would like to fix if possible.

Re: Sony XK-R100 car audio preamp troubles

Ok, so you ruled out the wiring....that would have been my first suggestion. Even now, it wouldn't hurt to wire it directly to your battery (red and yellow wire on +POS and black on -NEG). You can also try putting some tape on the face plate to make sure it's not loose, let it run for awhile with a little tape on it and the car off and sitting still and see if it still shuts off.

If you have already tried these things and are still having problems, I believe the culprit could be a dirty or blocked intake fan. Make sure there is not a mess of wires blocking the fan, causing it to overheat. I hope this is a help to you.

My unit keeps shorting out. wondering if its my car or the unit?

I would hazard to guess that you are running a speaker "ohm load" that is less than 4 ohms per channel. Or 8 ohms if you are running in bridged mode. You should NEVER blow a fuse. Re-check all your connections. Your "cutting out when the headlights are on" problem is due to low battery voltage to the amp. Use bigger wire on both your +12 lead and your ground lead. Make sure your battery to chassis ground lead is even bigger than your amps power lead. Make sure your amps ground lead is big, beefy, and short. And get a boost capacitor. When you have a huge amp in the trunk, you must treat it as if you are trying to run your engine starter from the trunk when it comes to the size of your hot wire and ground wire. Good luck.

Trouble with car stereo

Hoang00, to change the time on JVC's i believe you hold down "source" for a while and a menu pops up.
SSwaim, sounds like a grounding problem. Check the connections behind the dash, possibly a couple came loose. I would say possibly a bad car battery but the headlights thing points to a grounding issue to me.

No sound comes out of the left pre outs

It sounds like the preamp wire that carries the left channel signal between the HU and the 2ch amp has an issue. Here's two quick things to check.
  1. Check that both ends of the left preamp cable between the deck and 2ch amp is not loose or disconnected.
  2. Swap the left and right preamp connections at the amp. If the issue stays with the left channel, the issue is with the amp. If the issue moves to the right channel, the issue is with the preamp cable or the HU's preamp output.
Let me know what you find out!

The sub outputs are simply lowpass filtered preamp outputs for use with a subwoofer amplifier. They supply a lowpass filtered signal for a subamp or 'powered subwoofer" like a bazooka tube. Test your "basstube" for 12 volt input power and make sure the "sub" setting on the radio is turned up too.
