Installed the m6pro plus 2k, was super happy with it... until i installed hertz speakers all round and jbl 5ch amp.
There is feedback hum/whine through the speakers. This hum/whine was is not present if I connect the speakers to the headunit directly using the headunit built in amp.
(ran this way for 5months)
The hum/wine only occurs when a rca is connected to the headunit, this occurs on the front rca, rear rca and sub out rca, the hum/whine affects all output rca's.
With the rca's disconnected from the headunit there is no hum/whine from the amp/speakers (amp powered on by headunit just no rca's to headunit),
Only once a rca is connected to the headunit does the hum/whine occur, occurs on all speakers and all channels regardless of rca used (front/rear/sub).
if rca to front right only connected to the headunit, thats the only channel that he hum/whine occurs on. If rca to front left is connected to headunit thats the only channel the whine occurs on... so the whine is directly related to the rca being connected to the headunit.
Anyone connected their m6pro to a external amp using the rcas?
i have tried disconnecting all aux leads - reverse camera, wifi, 5g, mic, gps to eliminate those from being the cause.
Anyone a) experience this b) using the m6pro 2k connection to external amps?
My wiring is top notch, high quality 12gauge ofc, 4gauge power+ground, high quality rcas, all wire ends high quality connectors with heatshrink and attention to detail. Built many car audio setups over the years, first time ever had a hum/whine.
Thoughts? thanks guys
thanks.
