I've got the same problem you have but mine worked for a couple months and then when I was switching the amps, worked for another 30min and then they went silent. I still didn't open it yet but surely it's some kind of fuse that broke. Got to find the shematics of it to do some search here might be the problem...

Your pre-amp output has failed.
it will require repair.
use your voltmeter and measure the voltage from the RCAs.... it should be approx. 2.5v
If nothing - it is in need of repair.

Do you have the subwoofer amp connected to the pioneer thru pre amp connections; pre amp output of pioneer to pre amp input of Kicker amp. Page 10 of the manual explains how to adjust the subwoofer output. You can select the cutoff freq. that will pass to the subwoofer; The slopes don't match perfectly, but if you use the -12 slope , it should work fine.
Cut-off frequency:
50HZ

63HZ

80HZ same as kicker cut in freq

100HZ

Is my 1200 pioneer amp a good match for my 1200 watt pioneer sub


this is too close, your speaker wattage is alway's higher than your amplifier's wattage alway's to be safe because the hard pounding will make the speaker work harder, and this will cause your speaker burn out easily, though you can adjust your amplifier anyway's

I have a pioneer car stereo after a battery switch my amp gets power, but my subwoofers don't work


is the light on the amplifier on. is your remote wire the blue wire with power. if not you have a remote problem but if it all works check your rca's on the radio or your amplifier.

Can't fit subwoofer amp leads to pioneer DEH-2000MP Head unit


pioneer head units only distribute like 200 rms or so to the speakers. you might have to find a blue maybe even blue with white striped wire and nick it just enough to tie your amp wire around it. tape it up and see if it works.

Pioneer DEH-50UB


Hi again,

Appreciate the direct "Ask Me".

Let's try a process of elimination based on:
  • the Pioneer DEH-50UB is working OK other than it displays error communicating with the iPod at certain times (intermittent);
  • the iPod when played alone/by itself does not exhibit any freezing/hanging problems;
  • the iPod to DEH-50UB connector/cable CD-IU50 is in good working order since if it is not, then the iPod would not even be heard on the Pioneer;
  • the Pioneer's wiring are OK otherwise it would not be working.
Which leaves us the possibilities of:
  • corroded/dirty USB port/interface on the Pioneer DEH-50UB;
  • loose USB port on the DEH-50UB;
  • loose or corroded terminals on the CD-IU50;
  • corroded/dirty contacts on the iPod;
  • RF interference from communications equipment such as CB radios, 2mtr Amateur, mobile phones;
  • electrical interference/noise from the vehicle such as horn relay, A/C relay, fan relay, alternator;
  • electronic noise from navigation/GPS mobile equipment;
  • keyless/remote alarm/security system.
Additional actions that could be explored/done:
  • installation of choke/filter capacitor along the red & yellow wiring of the DEH-50UB;
  • additional grounding/groundstrap of the DEH-50UB to the chassis/metal/body of the vehicle.
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.

On my pioneer DEH-50UB the error message 'ERROR 19' is constantly appearing, this is addressed in the mannual however it merley advices you to restart the unit. obviously this is not satisfactory when it...


Hi,

To my knowledge, ERROR 19 on a Pioneer DEH series indicates failure on the USB connection. This is usually reserve for an iPod direct connection. If you are using such a device, pls:
  • check the Pioneer CD-IU50 USB Interface Cable;
  • reset the iPod;
  • disconnect the iPod and try again;
  • reset the Pioneer by removing the yellow and red connections. Pls note that some versions would require a security code when reconnected. Pls have this ready if and when your particular unit has a security/anti-theft feature;
  • reference page 32 of the manual.
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.

RCA Problem


You need an active subwoofer input in your amplifier.Which amplifier you are using? Only latest pioneer amplifiers has active sub input and sub output which can be connected to subwoofer.If you dont have active input then you will have to connect it the way you did in old player.
