Hi Fellow Members
I have just purchased a BKXXLS400 which I want to connect using the high level leads to my power amps. My problem is I just changed to class d digital power amps and the BK manual advises many class d amps do not like having the black/ground lead connected hence my problem.
I found instructions on Rel’s website that suggested floating (wrap in insulation tape) the black cable which should work without hum or issue for 70% of cases. I tried this and it didn’t work, lots of hum so turned off. There was further reference suggesting using a phone lead connected between the processor and sub which would provide the ground. Tried this but whilst the hum went the sub received no signal.
Has anyone successfully connected a BK sub via high level to class d amps and if so could you pleas,W advise how?
Thanks
Brian
