Re: ACC line error

Your stereo is trying to pull more juice then your electrical system wants to dedicate to the accessory line. Thats why Pioneer provides a secondary source wire that is attached to the inline fuse. Mkae sure that the fuse is no more than 10A as the larger fuse will provide too much resistance. Another problem that could be happening is that many auto manufacturers(foreign especially) have gone with lower voltage wiring harnesses. Use a multi-meter and make sure that you are getting a minimum of 12-14volts constant with key in the on position. If voltage is reading 9-10 volts which is common in some model cars, you may have to upgrade your system or just live with 3/4 volume. Good luck guys.

I had the same problems as the first guy but never got another answer back. I hooked up my yellow wire to my 12v constant boat battery and I got power because I could put in a disc and take it out but the...

Hi:) The yellow goes directly to the battery posative and the red goes to the ACC on the KEY switch if the radio is not connected to the posative ACC wire on the Key switch you will have no Radio at all the yellow is just for the radio's Memory and the CD motor and eject.

Here is a install pdf. site for that radio.

Panasonic CQ-C8303U. Hooked up an amplifier and it works with the radio but when i put in a cd the amp doesn't work. the receiver just plays with normal sound.

Verify your wire connections are correct. Keep in mind that if your amp is hooked up to the radios power antenna wire this is the problem. When you insert a cd the radio is designed to lower the antenna. If your amp is hooked up to the antenna wire the radio is shutting off the amp when you put in a cd Panasonic does this on most of all their units. You may have to hook your amp up to a separate switch to turn the amp off and on or hook it to your ignitions acc wire, if you hook it up to your ignitions acc the amp will stay on as long as your key is on even if you turn off the radio.

I am having trouble getting power to my new cd player. I have the orange battery wire hooked up, and also the ground wire is hooked up, and there is a red wire on the cd player that is a Ignition wire....

2 wires for power- one that is ALWAYS connected (remembers time, preset stations, etc.), and the other one you hook up to your ignition circuit (allows your radio to come on only when the key has been turned to ACC or RUN).

When you have wired this correctly, your radio will only come on when the ignition key is in ACC or RUN, and will ALSO remember the preset radio stations and the time, etc., when the key is turned off then back on again.

If you look at your fusebox, look for an ACC (accessory) junction that you can tap into. Also, don't forget that it's important to put a fuse in any wire you connect to a 12v+ source; don't rely on the fuse you are tapping into.

Hope this helps.

I dont no what i do whit the acc and what is my line i put in the power or the ground i dont have the plan for the truck and the radio

Use a voltmeter (VOM) to find 12v wire always ON, this connects to the receivers YELLOW wire. Then use the VOM to find a 12v wire ON with Ignition, this will connect to the RED wire on your unit, Then use the OHM function on the VOM to find a suitable GROUND, this will connect to the BLACK wire on your unit. The ACC wire is for activating a power antenna.

Can't go past 40 volume with Cd in

Check to see if the selector switch in rear of unit is switched to 60. if that is the case, then your speakers are not capable of handling the power. This is a safeguard Pioneer has built in to the unit. It senses the wattage allowances and self adjusts to the allowed wattage of the speakers. If this is the case, then you need to upgrade your speakers.
