This is normally a grounding problem in the amplifer. If you have a volt meter, check the voltage at the ground of the RCA input on the amplifier. If that voltage is anything more than just a few millivolts then you have a problem in the pre-amp of the amplifier. You should also only connect or disconnect the RCA jacks while the system is off. Otherwise you can get a loud popping noise that can damage the amp or the speakers. Check that voltage on the amplifer RCA jacks with the head unit not connected to the amp with the RCA cables, then if that is OK, check the RCA cables coming from the head unit. You may even have a voltage on those RCA's coming from the head unit, in which case, you have a problem in the head unit. You will be looking for a DC voltage, if you have anything more than just a few millivolts (0.070 +/- DC volts) on either of those then you have found the cause. After that, it will require a technician to be able to troubleshoot the amp or the head unit to determain why you have that DC voltage where it should not be.

Let me know if I can be any more help,

Dave

Kenwood kac-749s amp power indicator flashing red. what does this mean and what can fix it?


Either there is a short in the in the amp or hopefully just the speakers or wires going to the amp. disconnect any speaker input output and turn your amp back on(you will only have power, ground, and remote wires plugged in at this time) and if the red protect light goes away, then there is a problem with the input/output speaker wires, this includes your RCA's. If it's still flashing red then there may be a stray wire shorting to the amp in the speaker outs, other than that your amp may be fried. By the way, if it works without any speakers connected, including RCA's try connecting one component speaker at a time starting with your RCA's(if using them), speaker in, then speaker outs. If it turns into protect mode, note which speaker/RCA it was and replace or repair the short.

I have a turntable with a white and a red male RCA output cable. I am trying to hook it up to a Marathon DJ-1000 amp which has two TRS input channels - Channel 1 and Channel 2. Should I buy a twin female...


If I understand you correctly each channel has a single input in the amp, then yes! white goes into channel 1 and the red plug goes to channel 2 this way your signal will be stronger which translates into louder sound.

Where are the amps and how do i by pass them for the stereo


The amps are located inside the radio. Most in-dash receivers that provide for "pre-amp outputs" also called "low level outputs" do so by providing female RCA type jacks. These are often found at the end of a short (4 - 6 inch) cable and are usually color coded red & white or red & black (some receivers provide a yellow RCA jack for video in / out, too). To use these RCA audio jacks, you need to realize that one jack is for the left channel source and the other is for the right channel source for a stereo signal. You will have to connect a compatible plug and cable of enough length to extend to a remote amplifier's RCA input jacks. The vehicle's speakers would also need to be connected directly to the same amplifier's output terminals. Using the two audio (left and right) RCA jacks will only allow the radio to control balance of the left and right audio, no fader (front and rear) control is possible. To get fader control, you'd have to either have a radio with four RCA low level output jacks (front L & R *and* rear L & R), or use the radio's speaker (or high level output) wires and connect them to the amplifier's speaker (or high level) input terminals.

All unused receiver wires should be terminated in a wirenut or securely wrapped in electrical tape to prevent accidental contact with grounded metal or other wires behind the dash.

I hope this helps!

Red light is on when i connect input cable earthquake 1000w amp


Cables are either shorted, or deck is putting out too much power for input on amp... many new head-units will put out up to 7v on the output jacks (RCA) the amp may only want to see up to 1v will need to consult head-unit manual for adjustment of outputs.

I recommend you swap your left and right input cables to make sure it's not a source issue.

So from your headunit, plug the left channel output into your amps right input and your right channel output into your amps left input.

If the same side is still not working then disconnect both (or single speaker if it bridged) the speakers from the not working side at the amp. Connect the front and then the rear speakers individually and retest to see if one of them works.

If one does work then check the cabling and speaker connections on the one that doesn't. If it's shorting out anywhere it will stop your amp from powering that channel.

Failing that, it could just be that your amp has partly failed.

No output


Have you tried turning up the vol/gain control? Are all the switches on the amp set for full spectrum output? Are you sure you are using the RCA input and not the RCA output jacks (if it has such)? Check all the switches to be sure they are in the "most default" position. Something you might try, is to make a jumper wire to temporarily jump from the audio input ground to the power supply (chassis of car) ground. If this makes it work then you have a input ground problem in the amp. Good luck. P.S. As for epoxying the trace down on your other amp. If the foil is still in good condition then it should be ok to epoxy it down. If it needs some "help" then do that first, then epoxy.
