CAR: low level signal (MP3) to 3 amps (should convert to balanced?)- get lowest noise
hi,
I have this setup in car: 3 amps (front, rear, SW)
I bought theese 'signal' cables:
1)3meter of PROEL HPC 240 (balanced cable used for mics outer dia 4mm) - want to use it as STEREO CABLE with single shield with NEUTRIK MINI JACK
2)5+5 meter of PROEL HPC 230 (balanced cable used for mics outer dia 7mm) (each cable for each channel)
3)from previous cable split each channel to each amp (1+1+1, 1+1+1 meters) of PROEL HPC 210.
My question is, how to wire it to get minimum of noise... The signal source is MP3 COWON D2. It has higher output than ordinary mp3, but still lower than ordinary radio. => higher amplification => more noise.
In the shop i bought all of the amps and speakers told me to use those balanced (symetric) cables and make it double shielded. Question is does it help to wire the WIRE1 + GND together and use the WIRE2 as signal wire? Is it how he meant to it double shielded?
If I make somehow from the unbalanced output balanced somewhere behind the mp3 and convert it back to unbalanced before splitting it into amps, will it help? (the splitting of the signal will cause drop of the level of signal?)
Someone told me to put a filter into, and than someone told me that is a ********.
here is schema of used cables:

What is the best and cheapest solution for me?
