Question about Sony XM-1502SX Car Audio Amplifier

1 Answer

Over current light comes on.

Ok, here's the deal. I put a brand new duel car reciever in my car and I bought this sony amp used. I hooked it up to two new DUB subwoofers. Everything is new and thw amp is used.The person said it was good. The over current light comes on and there is no sound from the subs.I went to a profesional and he thought it was the ground. So I regrounded it to the car body under the carpet and the over current light still comes on. I just bought new RCA cables to see if that was it. Someone help me please.

Over-current lights are often caused by speaker wiring or impedance problems. If you're trying to use the amplifier in bridged mode to both subs, that may be causing the problem; re-wire the speakers so that each sub is connected to one amplifier channel. If you still get the over-current light, disconnect all speaker wiring from the amp and see if it still occurs. If it does, there's an internal problem with the amp. If it doesn't, then there's still a wiring problem with the subs. You may have a defective sub, or a speaker wire shorted against another wire or terminal.

No sound

What brand of reciever are you using. Most pioneers have a floating signal ground and the shield of the input at the amp needs to be connected to chassi ground. Also if you had a previous amp failure and the power ground in your old amp opened the current to power the amp will flow through the signal ground of the reciever and burn the copper trace on the circuit board in the reciever. test this by connecting signal cable shield to car reciever chassi.

I have a problem with my amp

Are they all green? If so, that's normal. They go red (or maybe amber?) when the protection circuit detects a problem.

How do i know if my amp is blown

Hey Yoo,


Go to Radio shack and get you an adapter that will take an earphone jack and convert it to RCA male.  You use this to simulate the signal coming from the reciever.  Hook up to a Cd player or Walkman, anything with an earphone output jack. Test that the device actually puts out music or anything worth listening to.  Connect the device to the input of your amp, with the car running, and the reciever turned on.. This will tell yo if the signal is getting from the reciever to the amp. You may not be getting signal from the head unit. 

If you still get no sound to the woofers, dsisconnect the woofers and try a different speaker.  If that speaker dont work,  Change setting and switches., and if you still get no sound, then your amp is toast.
