Could be a loos wire in the casing for the screen. if this happens while moveing this is most likely. if you are stationary then it could be a power fault because the power feed for sound and the power feed for picture are from two different sources.

Need wiring diagram for Sony XM-E70 Equalizer/Amp


You need 1 thick ground cable ( usually brown)
you need 1 thick power cable ( same thickness and wire as ground usually red )
you should have 1 rem wire ( thin blue )
RCAs, 2 for sub, extra 2 for 2 speakers.
The rest I have no idea what they are.

You need speaker cables to sub or amp.

Some products use different colouring. Maybe the 9 pin connector is for head deck to speakers.

Amp works on other subs, not on mine


Hello adeisenroth,

Sounds like the voice coil(s).

First make sure that the braided wiring going from the sub cone to the voice coil(s) have not come loose. Examine the braided wire all the way from the terminal to the cone. If one or more has come loose, it can sometimes be resoldered. Just be careful with the heat.

If all the wiring is intact, you can check the coils with a multimeter. With the sub disconnected, and the meter set to the lowest resistance scale, test across the speaker terminals. Depending on how the coils are wired you should measeure somewhere between 1 and 4 ohms. If you get "0" or no reading at all, one of the coils is open. If you get "infinity", a coil is shorted. Sometimes only one coil is bad and you can still use the sub, wiring it to the remaining coil only. Once you have determined that one set of coils is either open or short, you can remove the jumper and test each coil individually.

You can test most any speaker voice coil with a small battery. The best to use is the 9V type that has terminals right together. Connect a short piece of speaker wire to the sub terminals, and hold the other end of the "+" wire to the positive battery terminal, then quickly touch and remove the negative battery terminal with the "-" wire. The sub cone should move outward, and you should hear a brief thump. If no cone movement, and no thump, the coil is defective. Do not hold DC to a speaker for any period of time though, just touch and remove. And NEVER use a high-current battery, like a car battery for such a test. If the coil is not already bad, high DC current will damage it.

Either short or open, replacing a voice coil is a job for the Rockford-Fosgate professionals.

I have a Sony Xplod XM-1652Z 1000 W. I am using it to power my 2 Infinity 10" subs with 1052 watts on each Max. My problem is that when i turn on the volume too high the subs would stop working. My friend...


Sony audio products are not worth the buck, you will be facing worst problems in the future, my advice is just to change the amps. It is causing the problem, it cant handle frequencies when volume is turned up. and it may say 1000 watts but actually this is the peak rating your amp can handle thus meaning that it couldnt handle constant high volume usage, try crunch, kicker or hifonics amp, and look at the RMS rating on the amps when shoping.

I have a Panasonic twin subwoofer system. 7000w PMPO, 600w Rms multi amp system. With 2 main speakers, 2 woofers and 2 surrond speakers. The system is not working but the speakers are working properly.Is...


Yes it would be possible, acquire a home receiver or amplifier with either a crossover or an equalizer to filter out the high signals for the subs and is should work fine. Of course if the impedance does not match you do not want to blast the sound through them.

Sony xplod amp xm-1652z high level input connection


First off, if you're using RCA preamp connections from the head unit to the amp, you don't need to put anything into the high level input connector. But if your head unit doesn't have RCA preamp outputs, then connect the front left to the white (+) and white/black stripped (-) wires and the front right to the grey (+) and grey/black stripped (-) wires. There is no need to connect the rear speaker outputs of the head unit to the high level input of the amp.

Amp and subs just stoped working


Sometimes power problems are not visible. Did you check the voltage at the amplifier with a multimeter?

Sony xplod xm-554zr amp


if you are trying to run some highs with built in high-pass crossovers off of a amp that is setup for subs(amp is on low-pass) then your highs will not work. You are better off running another amp or running them off of your deck...
