Whining Noise - Car Stereo

[Carbon 34]

i also have a kicker 4channel amp

same noise, tried everything

somehtings thats even more strange is the fact i have four speakers connected to the thing yet i only need two RCA's connected for al speakers to work

someone explain that one to me as iv messed around with it lots and yea nothing works im guessing i dont have surround sound i just have two sterio sound

you could have 10 speakers or more on a amp, if they are wired right, OHM's law

the internal RCA bridge parrallels your input for 4 speakers to work on 4 channnels with only a left and right connected

the plug a new or borrow a RCA and run it outside the car into the boot, and start the car, is the whine gone ?

if so you know you need to replace or move the RCA to a better location and or replace it, ground shield is broken causing the ground to go back thru the radio , muti-path grounds induce noise

run away from power wires, and reground the radio, amp to bare metal. clean the battery terminals as well.

alternator whine is coming from A/C ripple and is fairly simple to figure out . very rare is it a bad radio or amp. without other symtoms

Hi,

sorry to dig this back up,

I have my RCA's running through my car in collugated piping, is it ok to have my speaker wires in that too?

thanks

I wouldn't put the two together , but if you don't have noise I wouldn't rush to redo it

power down battery side (in most cases to shorten the run and find grommets thru the firewall), RCA on the other side and speaker wires in the middle under the console

convoluted tubing is the word your after, and not required , since it tends to hold wires in a clump under carpets (not optimum), but use it for passing around metal or in the engine bays.

if your wires run on the other side of floorpan from a cat converter then I would use some heat proof protective or move the wires to a better area
