Hello,When the amp is turned on there is no sound the amp has been fine up until now what should i check?

Double check all of your fuses and make sure they are the corrects AMP. Other than that it sounds like the speaker wires came loose somewhere along the line. check on the subs and behind the deck. hope this helps

Hello everytime the power goes off & then comes back on my oven won't work until I turn the knob for the timer around as far as it will go then back again. My oven is rather an old type but maybe if you reset the timer or turn it that may help. Or check the meter box as well. dee

When you hooked up your amp, did you hook it directly to the head unit so that it didn't come on with the car? Did you find the inline fuse in the amp positive cable? Few things to check..

i deleted some songs then there was some space on my mp4player .. i hooked it off the computer again and it worked. dont know why, never mind, thank you!

Hello, I will make the assumption that your A/C runs fine when you are tethered to shore power. You will need to calculate your load. Add up the amps of everything in use, including the A/C. 3500W is the peak momentary output; look at your data sheet or tag to determine your continuous output, which will be less. It's possible that you're either pulling too many amps for your genset or there may be an issue with your A/C. Turn everything else off, and start the A/C. If the generator bogs down, you may not have enough generator. If it doesn't bog down, turn on your other items, one at a time. Ideally, your generator should have enough output to power everything in your 5th wheel, plus ehough extra for initial starting surge, like for your A/C, fridge, etc.. It sounds like your amps are close, but not quite there.

sounds like you have a shorted wire somewhere.

Hello christheline,

First make sure that the amp is powering up properly and that the input and subwoofer(s) are connected.

Check that the amp is not in "safe mode".

1. Press the MODE button.
Press the UP or DOWN button until “9” is displayed.
2. Press the ENT button.
3. Press the UP or DOWN button until “9-1” is displayed.
4. Press the ENT button.
5. Use the UP and DOWN buttons to turn safe mode ON.
6. Press the ENT button.

If this does not work, either the input from the head unit, the subwoofer(s), or the amp itself is probably defective.

Hope this helps.

Hello,

The level control controls the input level coming from your head unit (receiver) to the amp.

Your Sony users manual is a little vague on how to best adjust the level and other controls.

Here is one method that some installers use and works well with most amps.

Most 10" subs sound best between about 80-100hz and below, so start out by setting the LPF at about 80hz. The HPF will not be used. Next turn the bass boost and gain all the way down. Turn on the radio and set all tone controls, bass, midrange, treble to flat, usually "0" on most head units. Turn the volume up to approximately 3/4 volume level or just until you begin to hear distortion. Now, back the volume down until the distortion is gone. Next turn up the gain control on the amp until you hear the subs start to distort then back the gain down until the distortion disappears. Next turn the bass boost up again until the subs begin to distort, then either back the bass boost down or back the gain down until the distortion is gone. You may need to play around with the bass boost and gain controls to get exactly the sound you prefer.

Hope this helps.

try fittung a larger capacity battery this will help when you are parked for extended periods of time, but it does sound as if you have something draining the battery, try getting the alternater checked

1. check if the amp is in PROTECTION mode (might be a bad speaker or shorted output)
2. check the 'MUTE' switch
3. try to use the FM/AM mode to isolate an input source. If there is sound then check input source.
4. ...still no sound have a techinician check it.
