when my preamp volume is up i can hear a light thump thump thump squiggle squiggle squiggle sound ONLY when i change cd tracks.
it only happens with the shitty pioneer deck , if i hook up the 16 year old kenwood i have it doesn't do it anymore.
does anybody know how to stop this? its not very noticable but i'm OCD when it comes to stuff like this and i want it gone. Any advice on a cure?
Deck volume is 23 out of 30 , preamp is a PPI par-225 , gain for door speakers is all the way down , sub gain is less that 1/4.
All connections are secure as far as i can tell. And except for the left door speaker wire all signal cables and power cables are routed on seperate sides of car.
