Initially, pls confirm that the yellow wire is connected to a constant B+12 such as the + terminal of the battery. The red goes to a switched B+12 such as the ACC/IGN switch. If problem persists with the two pre-conditions satisfied, then there is an internal fault to the unit's logic circuitry.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

I have bought a JVC-R322 CD Receiver for my daughters Renault Clio and it connected to the existing cabling with no problems. However everytime I turn off the ignition and turn it back on again, the unit...

The vehicle has a constant power source that needs to be connected to the radio. If a fuse has disconected the circuit then you will lose your "memory" for your radio. Look in the owners manual for the fuse box locations. Use a light to find the fuse that has disconnected the circuit.

Removing of head unit

Depending on the model /make of the set , you will need the removing keys to pull the head unit out of the IN-DASH fittings. In most cases the use of flat screw driver might be effective. It must be inserted into the slot and the set pulled out.

I have a pair of kicker cvr 124 with a kole 1500 watt amp that is bridged to the woofers. the amp is 385 rms at 2 ohms where should the gain be to get the most power without distortion.

When setting your gain you want to set the gain high usually between 75% to 95%. if the gain is low than turning up the volume on your radio will only amplify the distortion coming from the under powered head unit. By turning up the gain you are maximizing the signal that is amplified coming from your head unit

Hi, I would like to install my kenwood kdc-w7534u into my mini one, how can I do it, can you help please?

To install your kenwood, you will need to first remove your stock radio. To do this, I believe there is a screw you can get at from the glove box. As well, there should be trim around the radio itself. Pry into that, and pull as hard as you can. It should pull off the trim-- from there, you should be able to remove the original radio.
While putting in your new head unit, make sure you have the right wiring harness. With this, you can plug existing wires into the new receiver. From there, all you need to do is make sure all of the previously installed wires are installed in the new unit correctly, then secure the unit and replace the trim.
Voila, you're done!

Radio is stuck on the FM3 channel, volume doesn't work, tuner doesn't work, pressing any other button causes NO DISC message to flash and radio to turn off -2009 corolla

Does Front Plate remove from Radio? If so Pop face plate and look for small pin hole that a paper clip could fit in. This is reset for Unit. Otherwise disconnect car battery for a couple minutes. I had similar issue with a JVC unit, It needs to be hit over its head to wake up.

When power is off radio loses memory what can i do to put power to memory please sendai cd 789

Hi, the aftermarket head unit should have a red wire for memory. This wire needs to connect to your factory hot lead wire. If you're not sure which one that is, tell me your car model and year so I can look it up for you. Thanks for using FixYa.

CD player will not work ,Err8' comes on when I insert CD, Make of radio, SOUND (4) FX110

Possible that either the mechasim is jammed due to a error in the system or the optical headd unit is faulty.
In both the cases you will need to remove the set to get access so as to probe.
Manually check the drive if there are any link errors. Clean headd and check , if not the head can be a suspect.

What kind of wire do I need to install Infinity reference series 605cs with a JL Audio 10" sub and a Alpine Flex 2 amp? Can I use my factory head unit?

You can use the factory speaker wiring for the Infinity speakers you should purchase a amp kit which will give you everything to install the amp. See site below
Well that all depends on the current audio system you have now is it just a basic or a premium factory system with a factory amp. Honestly you would get a better and cleaner sound if you change the factory head unit to a after market one which has preamp feeds and the higher the preout volt the better. Just make sure it is compatible with the amp volts input (Example 4v to 250mv) If you use the factory headunit you would have to by a high to preout adapter it connects to the exsiting radios speaker leads, but like I said before change the head unit you won't be sorry. Do not forget if you change the radio you need a radio install kit and the wiring harrness which converts the two radio plugs so you don't cut them so down the road you can remove the after market radio and just replug the factory right back in.

No sound out of left front speaker unless volume full high

Chances are that you either
a) Blew a speaker so you will have to get it replaced or fixed
b) A connection came lose between the speaker and the head unit so it may have to be reconnected
c) Double check the settings of your head unit and make sure the balance isn't on the right side, but more in the middle.

2 problems, what are the red and yellow wires on a Kenwood kdc-mp2028? and can you install a used kenwood without the remote?

You can use the head unit with no remote - that's just an accessory. As for the wires, the red is switched power (this gets wired in so that it only has power when the key is on - when the key is off, it turns off the radio). The yellow is constant 12v power (to maintain power to the head unit so that memory settings, treble/bass settings, and the clock are maintained when the vehicle is shut off).
