Installed a dual battery system with hellroaring isolator combiner in the jeep JK. its rear mounted with a 2/0 wire running up to a distribution block. block goes to all pre-existing main power. Bats are ground to body and frame with 2/0. (figured that problem from yesterday)
New head unit, amps and speakers, all wired right, power wires WELL away from RCA.
FAWKING ALTERNATOR HUM
not only that but another constant faint "tweeedleetweeedleeetweedleee" that is not varied with engine RPM.
it stops ONLY when no rca's are in the amps. a Ipod plugged directly into the amp does not do it (so not the amp)
Ground amps direct to bat.
gain turned down.
rca direct from head unit to amps in mid air.
head unit direct power and ground from bat.
disconnect hellroaring isolator.
run head unit on an ENTIRELY SEPARATED power supply.
combination of all of the above.
what the ****.
is my alternator bleeding that much ****ing RF that the headunit picks it up even when on an isolated power supply?
other things to try?
