When detailing the inside of my truck I bumped the back of my sub box. 1 speaker stoped working. then I moved my seat back and the whole thing stoped working. shut off everything disconnect power from battery and plugged back n and that's when I started to get the base like heart beat sound. I put in back up head unit, no difference. I changed out RCA's, no difference, re ran speaker wires no difference, changed out subs, no difference,changed out amp, no difference, checked wireing behind head unit, normal hook ups all connected nothing touching. checked groung, snugged. any help would be very helpful. thanks. btw its an autotek at1000, I believe its like 400 maybe 500 wt amp
The only thing I'm wondering is if you shorted out the RCAs somehow. Try switching the RCA's to another output on the back of the deck, if you have more than one set.
If that's not it...you will have to add pieces of the system one by one, starting at the deck, to see if you can troubleshoot the problem. Very Odd.
Good Luck
Testimonial: "hey thanks for the help. i actually went out there and disconnected everything and waited 20 min for it to reset itself. i hooked everything back up and it all came back to life like there was no issue to begin with, untill i started my truck. now its enjen noise. assuming a ground problem or remote wire. notice a slight kink n the remote wire. may b the issue. any other ideas im all ears. thanks."
SOURCE: Car amp's stopped working. Putting out a heart beat sound through subs but no bass.
could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.
SOURCE: Sony XM-2200GTX...Power, Green Light, All OK, No Sound!
Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier. As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.
SOURCE: Sony Xplod 500w green power light no sound
ok, i have a sony xplod 1000w amp, with a single kicker cvt12, and at low,very low volume you hear a little distortion,when the bass hits,but sounds great when volume is turned up,this is a new sub, and the old sub did not do this,both are 4ohm,
please, any advice would be great, i am new to car audio ,thanks [email protected]
SOURCE: Protection Light Is Coming On
You say the protection mode only occurs when you plug the RCA's in. Does it have to be both RCAs or just one?
The other end of the RCA cable is plugged into the HU?
It possible the RCAs have too much DC voltage on them, causing the amp to go into protection.
Is there a short in the RCA cable?
I would definitely check out the RCA connection at the back of the HU, as it sounds like there could be other issues there. Make sure the RCA connectors aren't touching any other metal (especially +12V).
SOURCE: Amp powers on but sub does not come on
I would double-check your RCA's on the amplifier. You should hear a thud if you unplug them. If not they are either not hooked up or defective.
