Id have to go look at it to be sure but I don't think so. I'm really thinking the problem is just ****** HLC and stock HU. I've never experienced this problem on an aftermarket and I'm typically on top of voltage drops not being an issueDoes it have pins inside and is rectangle? Most amps have this for those that wanna run stock HU and no RCA's.
does it look like this?No pic handy not with the vehicle at the moment either. I've seen something similar on my last amp which was a jl audio just larger ports
