Sub cuts out when I switch to CD player?

My sub works fine when I play music through the radio, but when I switch to my cd player, the amp cuts out. I think I might be somehow overdriving the input on the amp and it is clipping but my settings are pretty low. Any other suggestions on why it would instantly shut off like this? Dave

    Solved, thanks a bunch. It was weird because the wire that I used said power antenna was off a circuit city only vehicle specific harness and it labeled it as power antenna even though it was remote. So I got the true wiring diagram and pinout and switched them and problem solved, thanks again.

It shuts off because the remote turn-on wire to the amplifier is connected to the power antenna wire behind your head unit. The power antenna wire is only activated when the tuner is selected. You need to switch the remote wire to the blue/white wire from the head unit (currently you're using the blue wire). This is the true remote output, and will activate the amp whenever the head unit is powered on.

Radio plays but plug in the rc jacks for the amp and subs and get this grounded out sound plug in different deck works perfect the deck worked fine a week ago

check for loose connections at your speakers and sub. If you have a loose connection, they can ground the other out... look closely for loose strands that may short it out. most of the amps have overload protection and cut out when there's a short/ground out issue..

I had this happen on my sub and it acted like the whole system was cutting out.

Only door speakers have sound on the cd mode

the amp requires a 12 volt power constant, and a 12 volt "on" signal. you prolly have the 12 v "on" hooked up to the car stereo's antennae remote, meaning your amp gets power when the radio is on, cuase the radio is sending a signal to the amp (thinking that it is sending a signal to the antennae to raise)

you do have one of those collapsable antennas, right?

Switch your blue wires around.

You have put the remote antenna wire to the remote turn on of the amplifier. The radio cuts off the power to the "power antenna" when you switch to a different mode... so your amplifier is now losing the turn on signal it requires to stay on.

CDA 9885 No idea why it suddenly stopped working

It sounds like you have a bad ground connection. You need to take the radio out and check all the connections. I bet you have a loose one somewhere. That is what the problem was with my bronco

My amp only powers the subwoofer when the radio is on but wont when the cd player is on

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.

What could be wrong???????

The only thing left is the wiring, and or connectors from what you are describing.

You can try another amp and another set of speakers on the same wiring to see if they work. If not, the only thing you have left is the wiring and connectors (if connectors are used).

This suggestion is valid providing that substitution equipment is not defective.

No sound!!!!!

sounds like you blew an interior speaker.. it would cause the radios internal amp to shut down.

Receiver won't play music!!

Assuming that you have no sound from any speaker (hardwired and amplified from the phono/RCA output) I think it could be a fault introduced by your sub install. Have you tried unplugging the phono lead to the sub? If the phono lead has a short in it, it may effect the entire system. It could also be down to heat or lack of power. Have you got adequate thickness of cable and a high enough rating of fuse?
