Engine noise from Pioneer radio only

Hi

I installed a radio (Pioneer), an amp and some speakers into my car and got some engine noise. I tried everything I read from this and other websites but no luck at all. Then I tried using other radio's and there we go, problem gone.

Can anyone perhaps tell me why this problem is only with my Pioneer radio and maybe how to fix it?

Just installed a DEH-X1710UB new 14 gauge speaker wire soldiered and heat shrink applied to all connections. Hot wire checks good, key on hot checks good, know good grounding point (verified by OHS check)...


Absolutely. The ground wire for a separate amp will need to have a chassis ground, or it will attempt to draw a ground through the radio. Unfortunately, the amp draws allot of current, and the ground foils(all the copper traces in your radio) cannot support an amp ground. Most likely, those traces are probably burnt open. Additionally, these new radios have fuses inline with the foil. They do not look like fuses, so I wouldn't recommend trying to replace them. Additionally, if you pull the cover off, you could potentially destroy many components(mostly ICs) due to lack of ESD precautions(Electrostatic Discharge). If you require more assistance, or would like to inquire about having you Pioneer repaired, please visit my website at audioserviceclinic.com. BTW, I worked at Pioneer, as the Field Service Engineer for all audio products. Thank you.

That radio may have a lot of noise on its outputs, there could be a ground mismatch, or other problem.
Can you tell us more about the car, the radio, Amps, and anything else involved with this system? Thanks

Pioneer DEH-P6500 head unit doesnt turn on


Check your radio fuse. It is likely if you didn't disconnect your battery terminal that you may have blown a fuse.
About the speaker distortion, you may need to install filters to each speaker. They are not very expensive and can be found at just about any electronics store.

Loud engine noise through speakers


Jadrian - I purchased a DEH-P780MP and have the exact same sound. My suond however increases in pitch throughout the RPM range and is audible when operating the headunit on ACC. I have found this problem to being typical in Checy Sports cars since I can swap this head unit out from my camaro SS into my Mustang Saleen and the sound disappears. The same is true for a swap into my SUV. Never quite figured it out! I think the 12V line from the fusebox or from the battery itself doesn't have "clean" power.

Speakers dropping out & engine sounds


sounds like your amp is bad

remove the amp and hook your speakers directly to the radio if the problem stops
then the amp might be messed up

if you got another radio try the amp with that radio to "double" check that it is the amp

if the problem is still there with the speakers hooked to the radio then you need to fix or get another radio
