Amp goes to protect mode only on cd play

My boat has a sony stereo and matched amp. The amp is suppying the power to the rear speakers only. The stereo and amp work fine while listening to the radio, however when I put a cd in, the amp after about two seconds goes into protect mode. This only happens with cd playback.

MrLard, thanks for responding. I resolved the problem by disconnecting the blue feed from the stereo to the amp and wired the blue feed from the amp to a direct power source. Not sure of the technical reason as to why this worked but it did.

Do you get adequate bass on the radio, or is it a bit quiet on the low-end?

The 'Blue' feed is only for remote switching purposes and will only feed a low current, I think maybe 2A this will not be enough juice to feed and amp. You can connect a relay to the blue wire and use it to switch a main power from your fusebox.

With a separate amp you usually feed a fused live feed and either use a local earth (few and far between on a boat) or run live and earth direct
and the blue is the remote switch to tell amp/s
to switch on.

Is there a red or yellow cable on the amp
wiring harness?

You may find that if you have thr blue feed cable permanently wire to batt+ that the batt will drain after some time cos the amp will be on permanently (unless you have a master batt switch or ur boat, not sure, I'm a land-lubber)

Regards

Philip

What is "Press Power Protect"?

Hi Lois,
Stereo sytems have a protection circuit that alerts you by displaying "protect" when there is a electrical short circuit detected in the system, the most common short happens in a speaker, try disconnectig the speaker wires of both speakers(all speakers) at the back of the system, then play the CD or cassette player(although you will not hear anything with the speakers disconnected) and see if the unit goes into "protect" mode if the problem is still present then you have an internal short circuit and the system will need to be sent in for service or replaced(depending on age,repair costs). I would not recommend investing more than $80 into repairs. Now, if the unit does not go into "protect mode" then one of the speakers or speaker wires is shorted,be sure you check the conndition of the speaker wires before you replace the speakers, then you can replace the speakers(in a pair) and you should be back up and listening! Good luck and Merry Christmas !

Protector light is on

Hello justin83wint,

If the amp goes into "protect mode" immediately upon power up, it's most likely a short in the power/ground or speaker connections. If it operates normally for awhile and then goes into protect, it's most likely overheating.

In the first case, I'd suspect something in the wiring. Go here to troubleshoot the possible causes.

An amp will most often go into protection from overheating due to being operated at too low of an impedance load. Check the speaker specifications and wiring and make sure that the final impedance load matches the amps rating.

Hope this helps.

Jenson VM9311TS will not play all speakers in cd mode

YES!! You used the blue wire to turn on factory amp (blue wire to GM pink) you NEED to use the Blue/White wire. That is the amp turn on. The blue wire goes dead when you play a CD or DVD because it's for a power antenna. So, Blue/White ok?

Enjoy,

'Protected' usually appears on amps or combined cd/amp units when the main processor detects a short circuit in the speaker connections and the unit goes into 'protect' mode to stop further damage.Check the speaker connections. You may then need to reset the unit by holding the power switch in for a few seconds while powering on the mains cord for example. Sony A/V amps are notorious for this issue.

No Sound - boat stereo

Assuming that the four speakers are connected to the amplifier, then the amp is the most likely problem component. Does the amplifier show a power light when the system is turned on? Note that there is probably another fuse in the amplifier power wire, near the battery.
