I have a sony xplod 600 amp,hook it up,but the green light remains on,i have it hook to front speakers of my yaris,and i will hook the rear speakers to.why is the light on?

If the Sony amp (I'm not familiar with that one) has its own crossover and subwoofer output, use that, and set your crossover point for what sounds best to you. Honestly, it is best to have a SEPARATE two-channel amplifier & crossover for the 10" subs. Whatever you do, make sure you use a large capacitor (2 Farad or more) at the power input of the amplifier for the subs. This will help prevent blown fuses. (It is also a good idea to use at least a 1 Farad capacitor at the power input of the amplifier for the other four speakers.)

Try disconecting all speakers from the amp, turn it on after and if it stays on red it sounds like it had kicked the bucket. if it stays green start from their and check all of your wires for shorts (speaker wires) again. hope this helps...

yellow to yellow main power wire
red to red key wire
black to black ground
speaker wires are green purple for rear speakers and white and grey for front speakers solid wire color is power and black lines is ground
orange is dimmer switch you wont need it
blue wire is for power anntenna your car shouldn't have it and blue with white stripe is remote wire if you have an amp it will shut off your amp when hooked up any other wire unnessary for your car some head units need a anntenna adapter to work good luck. remember ground before anything and disconnect the battery so you don't blow the fuse

Try unplugging all the speakers and then powering the amp up, plug in one at a time to determine when the amp cuts out to protection. Chances are you may have touching wires or a speaker that is about to blow or at worst a amp going/gone bad

Guessing that you don't still have the owners/install manual.

On the back of the head unit there should be a group of unused/unconnected wires (with any luck they will be marked), one or more might be an amp turn-on or power antenna lead, so I suggest (with the unit turned on) testing each wire with a DC voltage tester so as to identify and separate any leads supplying 12+ volts. the remaining group will consist of speaker leads. Trial and error testing will determine the proper L & R rear speaker leads.

Good luck

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.

something is shorted in the circuit, or your subs. unhook the subs first and try it again, if it is still in protect then it is most likely the output transistors.

Have you disconnected the wire from the speaker?? and the amp?? Maybe the wire is pinched as I suggested?? If not then yes I would sy the peaker could be bad or the amp output on that channelis fried.
