Hi, sounds like you lost your amp turn on. Look for a blue, or a blue-white wire, that is your turn on and or power antenna wire. Turn on your strreo, check the output voltage with a meter on that wire. If you have voltage, check the battery power on your amp. If you dont have power on the turn on wire, use an acc. voltage that shuts off with the key. That should do the trick.

Check your ground wire! Relocate it to another place in the car and try to get a heavier ground wire aswell.

Clarion Marine Problem w Sirius CeNet Unit


When a CD changer or Sirius satellite receiver is added to a system, the source unit’s main wiring harness must be disconnected before the changer and/or satellite receiver’s CeNET cable is connected to the source unit. Otherwise, the source unit will not “recognize” that a CD changer or Sirius satellite receiver has been added.

Amp will not come on ,no light


Yes!!!!!!!!!! Your remote wire is what tells your amplifier to turn on and off it won't work without it. Assuming your stereo headunit is an after market unit it has the correct wire for this. what you have to do is pull out you headunit, and in the back of the headunit where all the wires plug into your unit there is blue wire with a white stripe. this is the remote turn on wire. connect a wire to that blue n white wire and run it back to your amp, insert it into to the spot marked remote. turn your head unit on and your amp will power up... if you have all the rca cables hooked up your amp should be ready to go.... btw good choice on the amp, kenwood is the way to go!

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.

Annoying thump from two 15" kicker comps powered by a lanzar vibe 266 amp


It sounds like it may be oscillating. This can be caused by a broken ground in the signal line. You need to check the RCA shield on the head unit.You'll need an ohm meter. The following page has more details. If the head unit isn't damaged, the shield ground could be open in the amplifier.

Remote works, but not the reciever


This one is tough one. It soundslike you have lost the connection between the flip face and the main head unit. I suggest you pull the head unit and get it to a bench for closer investigation. Look for and tears in the connecting wire harness between the Flip control, and the main Unit.

Clarion DRX9375r AM/Fm/CD Headunit optical output question.


I have the same HU and the same processor as you. First I only used the chinch cables to the processor, and from the changer.

The improvements you make; your headunit DAC and your chancher DAC wil not be used anymore. The differens; normal with a cd you convert a digitalsignal into analoge, in the HU or changer, and then you make it digital again in the processor, en put the signal analoge into your amp.

The advantage is; the processor uses the famous Burr Brown DACs and that is know by its good sound processing.
