The amp is receiving power, i tested it with my VOM. My RCA's are brand new, and i tested them. They are plugged in the right places. My Green LED is on. The Amp used to work then just stopped giving me any output. I tested my subs, and they are good too. Can i repair this?

Re: No Output from amp, green LED on
Are you absolutely certain your subs are in good shape? have you put a meter on them and measured the ohms as you depress the cone [causing the cone to move up and down on the pole of the magnet? do the ohms stay constant? go up to infinity[ suggesting an open] or go to zero or close to zero [ suggestting a short] both of these conditions will result in a zero or a very limited output from your amplifier, while still showing a green status light, if or when a full short or open occurs on the subs, a fault led will become lit, and whet that means is that u have fried the outputs....do a bit more testing with your vom....and good luck or try another speaker for testing purposes...

make sure its plugged in correctly and the wall plug is plugged tightly. I had a Dell C840 when the
charger got power it had a green diode that lit up. You could test your power supply with a volt ohm
meter. if the VOM is not showing any power coming from the power supply (assuming you have the
VOM setup to match the power output of the power supply) then the power supply is probably bad.
If it works then it could be the computers connection or battery.
Sounds like there is a problem with the amp. Try switching the inputs around for that output on the amp. If that does not help, Yes I would have to say that there is a problem with the amp output circuit.
Hello, here is Clarions wire codes. FRONT Right SPKR: +Gray -Gray/Blk, FRONT Left SPKR: +White -White/Blk, REAR Right SPKR: +Purple -Purple/Blk, REAR Left SPKR: +Green -Green/Blk
Brown Wire = Phone Mute Lead (If applicable) Yellow Wire = 12V battery lead in (Connect directly to battery) Red Wire = 12V Ignition wire (Connect to Acc switch) Blue/White Wire = Amp turn on lead Black Wire = Chassis Ground Orange/White Wire = Illumination Lead (Connect to dimmer switch) Blue Wire = Auto Antenna Lead (lowers power antenna Do not use for Amp Turn on! Use the Blue/White Wire for Amp,EQ, Ect.. turn on wire only
RCA Connectors if applicable:
Black RCA Harness: White RCA = Rear Audio Left Sub Output 1 Red RCA = Rear Audio Right Sub Output 2
Gray RCA Harness: White RCA = Front Left Audio Out to amp Red RCA = Front Right Audio Out to amp
First of all, you need to isolate what is causing the problem. No output (sound from the sub) could be a defect in the 1) Wiring, 2) Head unit, 3) Speaker(s), or 4) The amp itself.
Start to systematically eliminate the possible causes. Connect your subs to a known good system. If they work, it's got to be something else. Check the RCA cables from your head unit to the amp. Check the speaker wiring. Check the amp on-board fuses.
Make sure that you have output from the head unit. With multiple RCA jacks, it's possible to plug your cables into an input rather than an output (in the dark, behind the dash). If you have more than 1 set of preamp outs, try another set.
I have the same setup. Are you going out of the subwoofer output of the reciever? (it's purple.) then into the LFE jack of the subwoofer (also purple.) That's the only connection you need besides power. If you have those right, try using your cable for something else to make sure the cable is good. Is the indicator of the subwoofer green? Mine comes on with the reciever. Good luck!
have you tried new rca cables or a pop test on the output to the amp ? maybe even a remote wire disconnected ? even though u get a .5 ohm reading the rca output could still be bad try a pop test on it this should help you figure out the problem
The one plug on the back of the receiver is an rca-type plug and is designed to be connected to a powered sub, which would also have an rca-type input. Even if you connected it, this output carries a line level signal and is not powerful enough to drive a speaker. If your sub has 2 connectors (same as a normal speaker) then you have an unpowered or passive subwoofer. You would either need a powered sub, or to use an external amplifier of some sort...then the sub output from your current receiver would go into the external amp...and the amp connected to the passive sub.
Hope this helps.
Set the meter to AC volts and measure the AC voltage on the RCA cables where they plug into the amplifier. The black meter leat will go on the shield ground of the RCA cable. The red lead on the center conductor. You may have to turn the volume up to get a reading on the meter. At high volume, you should read at least one volt but the actual voltage will vary due to the audio signal.
If you get no voltage on the RCAs, measure the AC voltage on the input to the LOC.
Let me know what you find.
