Hi all,
I installed a new HU Alpine HD149BT and when I powered with HU up the tweeters were making a 'shhh' type sound. The volume on the HU was at zero. This sound was happening with the old alpine HU I had what I want to fix this issue.
Setup:
components: polk audio db6501 6.5
amp for speakers: jl 300/2
sub: jl w6
amp for sub: jl 500/1
HU: alpine 149bt
Any ideas?
Thanks
