Sony cdx mp70

The radio works, but when i switch it to play cd's only my subwoofer works. The speakers just shut off and all you can hear is the bass. It also displays a speaker with an "x" when in cd mode.

Re: sony cdx mp70

It may be that the remote lead on the amp has been connected to the auto antenna lead on the radio instead of the amp remote lead and because the auto antenna goes down when the cd is inserted it is turning off you amplifier, check the connections behind the radio or if there is a light on the amp check if the light goes out when you insert a cd

How can I connect ipod on SONY cdx-mp70. Is there a cable to do that, maybe in the back, in AUX?! Thanks

i use to have the same radio, the only way is to use the AUX with a RCA to 3.5min cable. i dont think sony has a ipod interface for that radio because of its age. Wish i still had it!

My Sony CDX-MP70 unit plays CDs and works on aux off my iPod but when I try to listen to am or fm it's nothing but static if I scan for a station it will just search forever, I took it apart but it all...

Check for a loose antenna connection, at the unit and where your antenna is attached to your car. Also, check fuses, some cars have 'powered amplified' antennas.
If those dont work, try resetting the unit. On most units there is a small pinhole behind the faceplate(not on the faceplate). Could also be the internal tuner has gone out...

Hope this helps

Where is the aux input on the sony cdx-mp70?


check the front of the player. If you don't find any Aux input then it means your player does not have Aux input.

Take care.

Poor sound

Sit low Bass @+3 / Mid@ 0 / Hi+10
Add SubWoofer with separate Amp and use low pass filter @78hz cuttoff.
It's a cheap unit -don't expect High Fidelity & a warm EQ<

Subwoofer in my car works only on tuner

I had the same problem. most radios have a power antenna wire and an amp turn on wire it sounds like your amps are being turned on by the power ant wire that loses power when you put a cd in try swapping the blue with blue and white wire this should solve it

Troubleshooting in car cd player

that is very strange but it could be that when you put the cd in the radio it maybe sending out a quick shot of amplified power I would try disconecting the subs put in a cd let it play a little then plug the subs in while the cd is playing and see if they work if this works you may to get a new radio or put in a switch to turn the subs off or some type of momentary circuit breaker I'm just trying to help I never saw anything like that before good luck........

No sound on radio or cd

if the fault was intermittent it may suggest that there are some dry joints on the internal amplifier which you will need to resolder or there may be a speaker wire shorting to ground, remove the radio and look if there are any signs of damage to the speaker wires

It depends which vehicle it has been installed, some radios have to be screwed behind the dash but most you will just need sony removal keys, remove the trim and slide the keys (one each side) down the radio and then slide it forward if you're lucky it will come out without much force. Have fun!
