Subwoofers Popping and Hissing (DSP Amp)
 

Hi all -

just spent a couple of hours tracing all the connections under the radio rack, amp and subs (4.8iS) to try and eliminate a random loud popping noise which happens every several seconds, interspersed with white noise hissing from the subwoofers.

Chased all the connections but everything seems sound, however the fact that there is intermittent white noise leads me to suppose that the DSP amp is no good.


Thoughts??
