I know these radios are far from top of the line, and I have read they are prone to RFI. That being said they look the part and have Bluetooth so I am trying to make this work. I am getting a high pitched sound out of the component speakers I just installed and I can’t figure out why. Here is what I have
1989 Burb
M4 retrosound
Infinity reference 3.5 in the dash corners
Kenwood 4x10s in the back
6.5 Infinity Ref components in the kickpanels with a pioneer gma3702 amp
The dash and rear speakers are fine and have been for a year. It’s the new kickpanels that have a high pitched sound. If I mute the stereo or disconnect the RCAs the high pitch sound goes away. If I crank up the stereo real loud you can drown out the sound. BTW this is happening with the car off and key in accessory. I haven’t driven around yet as I am still troubleshooting. If I disconnect the RCAs from the retrosound and run the amp and kicks off my computer it sounds great. I’ve tried running separate power and ground wires to the radio and amp direct from the battery but I still get the sound. I’ve tried unhooking everything from the radio except power (switched and constant) and ground, and then rca cables and remote amp on wires direct to the amp. I’ve tried different RCAs. I’ve run short RCAs straight from the radio to the amp and not through the carpet and floor. I’ve pulled the radio out of the dash and run it on the floor. I’m out of ideas on what to try to at least isolate where the sound is coming from. I may have to abandon the retrosound but I’d like to try and get it to work. Any ideas on possible troubleshooting scenarios to run?
