it could be your input section on your amplifier were you rca jacks go in but you should check and make sure it aint your cd player out put on your rca jacks the easy way to check this is with a meter and a cd playing in your cd player turn your meter on volts usually your out put on rca 2.5v some cd players put out 5v so take your postive tester needle and stick it in the inside part of your rca jack and take negative tester needle and touch the outerside of the rca jacks and see if you get any reading if do that good on that part but on your amp no it could be in the input section of your amp it could be as simple as a burnt trace wire on the bottom circuit board or a op amp chip theirs alot in a amplifier but you can test them with a meter to find out witch one bad but i would take it to some one that work on amplifiers if you dont know how to test them
It sounds like the wiring between the cdplayer and the dash has come loose. When the wires are not making proper connections some of the speakers or functions of the radio cut on and off.
This is just my first thought and the easiest thing to fix. You will have to remove the cd player from the dash. After which you will want to check the wiring. Chances are your cd player has a harness if it's an aftermarket cd player installed in your car. If it does there will be two sets of wires to double check.
Just make sure all the wires are securely twisted together (the sets of wires) and taped up with electrical tape.
Try that and post back if you have any further questions. Thank you for choosing Fixya!
most reputable car audio shops can give you (or have thier own) repair techs. is the new amplifier rated down to the same impedence you have your subs wired to?
Any protection lights coming on the face of the amplifier?
It has a lights that come on for Thermal, DC offset, over/under voltage, reverse polarity and short circuit protection.
May be a faulty turn on module.
Get it repaired before more happens internally for a costlier repair.
The reason it used to cut-off at 60% volume as you said before, Is probably due to the "protection circuit mode" being tripped.
You can try resetting it by turning off your CD player ,removing the Batt( + ) and Gnd ( - ) terminals from the amp for a short period. Reconnect them Allow the amp to receive power but not switch on (keep cd player/remote power source off)
If you dont know how to wire the CD player to control the amps power status , the easiest way is to connect the 'power antenna' or similar low voltage throughput wire from the head-unit to the amp's Remote terminal.
My old amp did the same thing ,and would need to be powered off/on before resuming sound output, sometimes I had lots of trouble with the protect mode staying on , even with little or no sound output from headunit.
The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.
