We moved the ground wire for the stereo, and now the amp will not come back on. What could be the problem? We used a test light on the remote wire and other wires and we are getting power. when you turn the car on the red light comes on and goes right back off. Please help

Re: amp will not come back on
Try moving the ground wire back where it was and see if it works again. Most likely you have a bad ground. Try grounding your amplifier to your back seat mounting bolts if all possible. Try scraping the location 'til you see metal before you ground your amp as well. Hope this helps!

USE PROPER GAGE WIRE CHECK ALL FUSES TO THE BATTERY,THE FUSE ON THE AMP,MAKE SURE YOUR CONNECTED TO ELECTRICALANNTENA POWER WIRE ON STEREO (ITS USUALLY BLUE WIRE OR OARNGE WIRE ON BACK OF STEREO)BE SURE YOU HAVE A GOOD CLEAN METAL TO METAL GROUND WIRE CONNECTED TO BODY CHASSIS///SOME NEW STEREOS HAVE DIFFERENT WIRES ON THEM FOR CONNECTING AN AMPLIFER BE SURE TO CONNECT TO THAT WIRE THE REMOTE AMP PWR WIRE
If you have a voltmeter or a 12V trouble light, check to see there is 12V at the remote terminal when everything is on. The remote wire coming out of the head unit cant supply a lot of current (usually around 1/2 amp). even a quick short to ground on the remote wire can render it useless.
OK ! FIRST THINGS FIRST. DID U TEST THE AMP FIST. BEFORE U STARTED INSTALLING RCA CABLES,AND REMOTE WIRES. LETS DO THAT FIRST.GRAB YOUR AMP.SET IT ON YOU WORK BENCH ,TABLE,OR CHAIR.THEN GET (2)PIEACES OF #10 OR #12 WIRE W/1 OF THE WIRES HAVING A 20AMP FUSEABLE LINK ON IT.NOW THE WIRE W/THE FUSEABLE LINK ON IT.CONN THE REMOTE(REM) AND THE 12v + ON THE AMP AND HOOK THEM BOTH TOGETHER ON 1 SIDE OF THAT FUSEABLE LINK WIRE. AND THE OTHER WIRE HOOK IT UP THE - GROUND SIDE OF THE AMP .NOW PICK UP YOUR AMP OPEN UP YOUR HOOD.MAKING SURE THAT NO WIRES OR THE AMP IS TOUCHING THE + 12V OF THE BATTERY. NOW CONN YOUR GROUND TO GROUND AND THE FUSEABLE LINK ON THE +12v SIDE OF THE BATTERY.NOW THE AMP SHOULD HAVE CAME ON. LOOK 4 A SOLID RED LIGHT OR ANY SIGNS OF A SOLID LIGHT THAT HAD CAME ON.
In Car Amplifiers have 3 main power wires: Live +12v (Fused wire direct from the + side of the cars battery)
Ground (Direct to car earthing point (anywhere cleaned of paint for good connection)(I tend to use boot lock)
Remote (This wire should be connected with the switched live wire coming from the back of the stereo, this is Only live when the cars ignition is on)(there should be 2 power wires coming from the stereo usuallyredlive +12v and yellowswitched live, depending on the cars original wiring, try moving the remote wire from where you have it, to the other live wire
12 VOLT FROM THE BATTERY SOURCE GOES TO 12VOLT BATT CONNECTION.12 VOLT GROUND RETURN MUST BE FIXED TO THE FRAME OF THE VEHICLE.SOME VEHICLES HAVE FACTORY GROUNDS UP HIGH ON THE SIDES OF MOST VEHICLES, U CAN USE THIS GROUND LOCATION. IF CONNECT REMOTE WIRE FROM THE RADIOS REMOTE TURN ON LEAD WHICH IS A BLUE/WHITE WIRE OR A STANDARD BLUE IF ITS JUST ONE BLUE WIRE. CONNECT THIS LEAD TO THE REMOTE TURN ON CONNECTION ON THE AMP , SOME KENWOODS HAVE TWO ,INPUT AND OUTPUT LEADS.U ALSO NEED A TEST LIGHT, OR U CAN USE A SPEAKER TO TEST FOR POWER AT UR CONNECTION.IF U USE A TEST LIGHT , CLAMP THE END U WOULD GROUND TO THE VEHICLE, TO THE AMPS GROUND, THEN TOUCH THE PROBE END OF THE TEST LIGHT TO UR WIRED CONNECTION TO VERIFY U HAVE POWER AND GROUND TO YOUR CONNECTION.IF TEST LIGHT DOESN'T WORK ,CHECK UR FUSE AND REMOTE TURN OR LEADS.
