Sub system won't play can't find in settings amo hooked up to subs yet still nothin help plz


Is the amp switching on? There are two 12v wires that have to be connected. One from a direct constant 12v supply source, and the other one from the ignition switch 12v source.Find a single 12v. supply which you can take from the lighter connection and then trace a 12v wire that runs from your ignition switch. This is mentioned in the amp manual.Double check. If the amp is coming on but no sound, then your wire connections from the amp are not correct.Or you have also connected the speaker wires incorrectly.Remmember not to connect the earth of the speaker wires to the direct earth(body of the car) but to the earth wires that are shown in the manual as this could blow the amp power IC. The earth wires of the speakers are marked -- and + respectfully and are also colour coded.You should have a RCA female plug connector from your amp to the subs. Check everything double and if still no luck their is a possibility that you could have blown an IC in the amp from wrongly connected wires. Hope this is not the case.

A friend recently gave me a Pioneer deh-p5750mp car stereo cd player and I'm having trouble installing it. I have successfully managed to connect the positive, earth and constant power wires and...


One thing to remember about most radios, the RCA pre amp circuit will still work even if the mosfet power amp inside the radio does not. The best way to know if the amp inside the radio works is to use one matching color pair coming off the radio to wire up a random speaker right to the radio. You can use just about any old random 4 ohm speaker that is laying around to check it. The best solution if the amp inside the radio is blown is to replace the radio or amp the pre amp outputs with a small 4 channel amp. Oh, by the way. What vehicle are you connecting this into? And does the vehicle say Bose, Infinity, or ect sound or Premium sound? These usually denote a factory amplifyer already onboard and requires special connections to get the signal to these amps to then be delivered to the speakers.

I just brought clarion cd player had it fitted by vauxhall dealer and when i put the key in the ignition turn key to aux cd wo'nt come on but when you turn the key to start engine cd player...


Sounds like the unit was not wired into the car properly..the dealer needs to make sure that the switched lead that they connect the red wire from the radio to is hot when in both run and aux(accessory) positions on the ignition switch...it sounds like they may have wired the switched lead to the wrong accessory lead

Installing a dual cd player in a 2006 scion xb but dual cd player wont cut on unless both consistint power an ignition power are both together, making it impossible to hook up for memory.


The yellow wire needs to go to a constant source and the red wire should go to a switched (ignition) source. There should be a wire that is hot even with the key off.

I have an older car sterio by sony it has rca jacks that say front and rear is tis my speaker wires? if so how do i hook them up to my speaker wires?


RCA jacks are used for outputs to an amp.
The speaker output wires will normally be a color per channel, the "A" leg will be the color and the "B" leg the same color with another colored stripe running along its length.
As for power supply the yellow would be for memory and needs to be connected to a permanent power supply ie direct to the battery.
The red is for main power. Connecting it to the ignition will switch the radio off when the ignition is turned off, or connecting it direct to the battery will allow operation of the unit irrespective of the ignition switch position.
The blue is used to power additional accessories such as an antenna or amplifier. If you are going to operate an electric antenna through the unit it is best to use a relay.
Black is to be connected to battery negative or any good earthing point on the vehicle body. For further assistance please leave a comment. A model number of the stereo would also help if you need more in depth assistance

Need to know where to connect this last wire so i can play my new cd player in my truck


You need to find a wire under the dash that is a 12V switched wire, it is used to actually turn the radio on and off, normally works with the ignition switch.

I have got a kenwood cd player but can,t install it into my vauhall corsa because i need a seprate battery 15amp yellow cable to run from the battery supply to connect up to a cable attached to the radio...


You can test one of the wires from the harness connector for a contant +12v with a test light. They are sold at your local auto parts store for less than five dollars. The harness connector that i'm talking about is the harness connector that originally connected to the stock radio. All of the connections needed to install a cd player are all on that harness wire. The test light is simple to use, all that's needed is for the alligator clip to be hooked to ground. And from there, you can determine from tapping which wires are for the power supply. The power consists of three or four wires. They are ground, +12v ignition, +12v constant, and if installing w/ an amplifier, the remote. This is the usual place most people connect the wires for a new head unit.

Panasonic CQ-DP620AEUC pinout (car radio/CD player) bought used from my brother. He didn't have the wiring pinout diagram anymore. Which wire is the "memory" connection to 12 VDC?


Yellow wire is always the memory or back up, which is always 12 volts even with key off. Red is for ignition, 12 volts only when key is on. Black is ground. Speakers are color coded in pairs, the grey and white pairs are the fronts and the green and purple pairs are the rear speakers. Each speaker wire with a black stripe is the negative speaker lead and the solid color is the positive.

If you need more help just let me know and a FixYa! rating would be appreciated.

Thanks,
Dave
