Amp enters protection mode at high volume

Hi! I have 4 speakers (2 6x8 50rms and 2 6x9 80rms pioneer) hooked to this amp, a DEH-4800mp player and a 10" woofer hooked up to a 760w pioneer amp. At high volume, and even at normal levels, the amp enters protection mode and it goes off (only the subwoofer keeps playing) and on until I turn down the volume. If tried changing the gain levels from one side to the other, and the same thing happens, only at different volumes. Is there an easy way to check if there is a short cut on the speakers or anyways, what could else could it be? Because even the factory cd player would go higher. I've tried running it cold and the same thing happens so I've checked out a temperature issue, although it does heat up quickly at high volume.

sometimes if the power cable and the ground cable are frayed and touch it will short out the amp temporarily check to make sure allof the wires aren't touching each other

SOURCE: sony xplod 500w 4/3 channel

If the speaker is a 4 ohm DVC (two 4 ohm coils), you can't wire it to get a single 4 ohm load. Try connecting one coil to each of the two rear channels. It may not be as loud but the amp should operate without going into protection.

If the two 4 ohm coils are in parallel, the amp is driving a 2 ohm mono load. That's probably why it's shutting down.

Most likely one of your subs are blown, or the Ohm's are too low for the ampliphier. Try hooking up one speaker at a time to the amp and see if it does the same thing. If it shuts off on one of the two speakers, that speaker is most likely blown.

SOURCE: sony xplod amp(XM-1652Z ) power/protect light

if your amp is overheating your sub is needing to much power that the amp doesnt have.
if its cutting out and the red light comes on you need to check the wiring. nothing not even the tinyest speaker wires can be touching.
proper wiring would be your best bet.
but i would upgrade amps.
cheap bang isnt reliable.

Speaker hook

Hi it's a problem in the set up . This model , like few other in the line have the possibility to switch the "back speakers" ( through harness or RCA) into "BASS SPEAKERS" what give you a possibility to hook up a Sub without an extra amp .
To switch it back just follow the Section 2 / Sw control of this link http://www.pioneerelectronics.com/StaticFiles/Manuals/Car/DEH-3300UB_OwnersManual0902.pdf

I wont the speakers hooked to the cd player no the amp

check were the speakers are installed for pre existing wiring they probly left it there.. if not then you will have to run speaker wire from your stereo wiring harness to your speakers. if the speakers were hooked up to the amp then the wire in the harness should be vacant and you can use it if all the wires are connected then that means that you just have to find were that wire leads and hook your speakers up to it.

Check speaker wires for short or touching. Try unhooking one speaker at a time then try it. If it doesnt do it on one that speaker/wiring is your pulprit.

PIONEER 300 WATT CAR STEREO AMP WIREING HOW TOO

depending on how many channels the amp is, you may not be able to hook everything up to it.

usually you have a separate amp for subs. 4 channel amp for the speakers in the car, and a mono amp for the subs.

To hook them all up to the same amp you would need an amp with 5 channels. It wouldn't work out right.

If you have a mono amp its only for subs.

If you have a 2 channel you can either hook it up to the rear speakers or bridge them to mono to run the subs.


you need a channel per speaker basically.

Xm-2002gtr amp keeps kicking protect light on

check your amp and speakers and make sure their both hooked up 4 ohm instead of 2 ohm because if you have 1 set of voice coils on your speakers they can only be hooked up four ohm and not bridged to your amp because if you keep trying this you will lock up your speakers if the speakers are only 4 ohm than just hook them up regular to each channel on your amp if your trying to brigde four ohm speakers to your amp it will keep going into protect or worst case scenario you will fry your speakers and you can check your ohm with a ohmmeter trust me my brother owns a stereo shop

Amp went into protect, but front speakers sound distorted too

If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.

At high volume sound shuts off, subs still work

You most likely have a shorted or damaged speaker, which is causing the internal amp chip to shut down (but does not affect the preamp outputs). A test you can do is to fade to one speaker at a time and turn it up to se if it shuts down. Repeat with each speaker until you find the one that causes the fault. Then replace it.

Speakers dropping out & engine sounds

sounds like your amp is bad

remove the amp and hook your speakers directly to the radio if the problem stops
then the amp might be messed up

if you got another radio try the amp with that radio to "double" check that it is the amp

if the problem is still there with the speakers hooked to the radio then you need to fix or get another radio
