Sony Xplod Amp

I have this Xplod amp for quite awhile and not had a problem with it. Just an hour ago i was driving and it cut out. I stopped to look at what the problem was. When i looked at the amp a RED light was on saying OVERCURRENT. what does this mean and what are all the possibilities of why it is doing this?

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

I got Sony Xplod XM-ZR704 700W 4/3/2-Channel Car Stereo Amplifier and 12" sub. it play good for continuous 2 hours but after that starts tripping and goes on off. i checked all wires and connections.


Amp is probably over heating. Make sure the ohm load of speaker is good for that amp. This amp is not really built to handle a bridged 2 ohm load. Make sure ground wire is clean and tight to the body chassis.

Check your subwoofer for resistance. It is more likely you blew a sub than a channel on the amplifier. If your subwoofer has no resistance, which can be checked using a multi-meter, then it is blown.

I have two sony xplod 12" speakers wich can hold


You only gave us the model of the amp so I will make an assumption that your 12" subs are the Sony XS-GTX120LW. First, they cannot hold 1200 watts a piece. They are meant to be powered with 350 watts RMS. They will hold 1200 watts peak. That means that 1200 watts for a few seconds will be ok. Past that and kiss them goodbye!

Next you indicated that bridged the amp. Since the subs are both 4 ohm single voice coils did you wire them in series or parallel?

It sounds to me like you wired them in parallel resulting in the amp seeing a 2 ohm load. The amp you referenced is only stable when bridged at 4 ohms.

Has the amp begun working again once it cooled down? If not you could have fried the outputs by having the resistance too low.

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.

Sony Xplod Amp


well you might want to try using 30 amp atc fuses instead of 10 amp fuses on your amp, because you are getting an overcurrent from your alternator then from your battery. I have the same amp and you will find that your subbs will hit better too. also check on your ground wire from your amp as this also will cause the RED light to come on. :)
