most-likely amp output stage is blown and needs to be replaced.
local techs can do that for around $300 and it seems to be generic job
Avantegarde Duo repair.
Thanks in advance for any help. I have a beautiful pair of automotive blue AG Duo’s (not the 18ohm version) and both my SUB225’s have failed. I actually have 4 SUB225’s. One still works fine, one blows a fuse immediately and the pair that were in use are not powering up but the fuses are fine. Happened last week.
I live in the Chicago NW suburbs. Any recommendations for a quality shop to diagnose and repair?
Additionally does anyone have an opinion on value as is for someone with the knowledge to repair?
Thanks,
Jon
