Question about Audio Players & Recorders
Hello, is this a Radio Shack PA amp or Jamo amp? The unit is probably in "Protect" mode. Is this a PA system or a receiver...receivers have a protection circuit that will not let the speaker relay activate if the amplifier output section is shorted and sending voltage towards the speakers...so they won't fry!!The speaker relay should activate within 3 to 5 seconds if your output section is ok.

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.
