You will need to check that all your earth wires including to your battery are clean and have a strong connection to the body of your car. the other problem may be your trying to run to much power out of your amp and it is triping out. if you have to many speakers runnig or diff speakers running diffrent ohms off the amp( as in rear speakers and a sub off the amp your current draw on the amp will trip it out, for that you will need a bigger amp. Try your earth wires first.

It has stopped workin and the red light is flashing.Is this a code and if so how do you read it


The red light is a power protection circuit designed to shut the amplifier down due to an overload or wiring problem. If the amp was playing then shut off, my guess is a problem with the speakers or the speaker wiring. Some amplifiers are only stable to a certain load. For example, most car audio speakers are 4 ohms which is the resistance placed upon your amplifier to produce a certain volume of sound. If you bridge two 4 ohm speakers together in parallel, you cut the resistance in half, thus increasing the amount of power (and volume) to your speakers. This also creates more heat and could, in effect, shut your amplifier down. I would find out how the speakers are wired to determine the resistance of the load your amplifier is pushing. Also check the grounding.

Trying to drive this pair of speakers. Do you need to have batteries in them? do you have drivers or are they plug and play? If they need drivers can you send them in an email?


What manufacturer of speakers? What model-number?

Most speakers do _NOT_ have any "plug-and-play" capability -- they simply are electro-mechanical devices (amplifier, analog controls).

The amplifier needs power, either batteries, or an AC adapter, to convert the low-level outputs from the sound-card to bigger signals -- enough to move the speaker-cones to push air around, to make sound-waves.

My speaker stop workin and the amp is fine and everything is hooked up right


Looks like the speaker is blown , or the wiring inside the speaker is broken. To test if the speaker is working, simply hook up the terminals to the ends of a AA, AAA or C battery. Speaker should make a noise, and the cone should push outwards ( or pull inwards, if the polarity of the battery is reversed). Also test the wires that are hooked to the amplifier with a speaker that you know is good working order, just to make sure that there is nothing wrong on the wiring, on that particular channel in the amp.

Suddenly, amplifier stopped giving out sound. Controls and display seem to work fine. If it is blown fuse, where is it & how can i replace it?


Does it stop on both channels? It sounds to me like the safety circuit is activating. This usually happens when either the volume is too high, or the speaker load is too great (i.e. usually loads less than 4 ohms will do this) or, the amplifier has an internal short causing the amplifier's output stage to become un-balanced. Does the sound come out nice and clearly through both channels? How long does the receiver play before the sound stops? How loud are you playing the music when it stops like this? If the sound is reasonably clear through both channels at regular volume, then there is probably nothing at all wrong with the receiver's output circuits. If the amplifier is being played at regular volume or even lower volume for quite a while and then quits, perhaps the receiver is getting too hot and it's thermal sensors are activating the protection circuit. Make sure that when you operate the receiver, that there aren't things laying on top of it blocking the unit from venting and cooling properly. Make sure it has plenty of breathing room - amplifiers (most of them anyway) are inherently subject to producing heat. If the amplifier only quits when played at high volume, well then that's probably the problem - it's probably not meant to deliver such power that you're asking it to - especially if you're driving a heavy load such as 4 ohms or less. If you're running several speakers on this unit, try scaling back to just two speakers for now, and make sure these are 8 ohm speakers. Play the unit for a while and see how it does.

Hooking up system to a factory infinity sound system in a jeep grand cherokee.


Tap into a signal wire (rear speaker wire) using a line level converter.
These convert the High level speaker wire output into low level RCA output that is accepted by your amplifier.
c5b61ef.jpg Get a good one Pacific Accessory Corporation (PAC) sni-35 is the best IMO.
The TRUNK-LOC is the SAME as the SNI-35 - but it incorporates a voltage sensing input - so you dont need to run an additional turn-on wire. The voltage is sensed through the speaker wire - and it turns on the amplifier.

Then you will need a fused power wire from the battery,
Ground to chassis, and remote turn on lead (if you use a standard line level adapter).

An amplifier installation kit will give you everything you need to add 1 amplifier (except the converter)

Hi i have a 600 watt sony xplod amp model xm-554zr and it recently stopped working. when i turn my car on the amp turns on but only for a sec then the protection light comes on, on the amp and it wont...


sounds like maybe a speaker short, try unhooking your speakers and then powering up your amp, if it then powers up with the speakers unhooked try hooking up each speaker one by one untill the amp goes back into protection and then you have your bad speaker.

Nad c350 no power at all


check your output stage for bad speakers cable or bare wire of cable touch the body of amp----short circuit speaker cable----bad speaker it self------ bad input cable or defective input device .
disconnect all and check if it is ok---start to connect one by one from input to outputs------if all above failed you must contact service center for help.
