I'm still around. Just haven't been on the board for a while. Truck is a little worse for wear. Clear coat on roof and hood is peeling, needs an alignment and some other maintenance.
Here is the LOC that I have uses the same circuitry as their NE-774V LOC. So I would assume that the one I have has signal level permanently set at the maximum 9.5 Volts. You would have to contact them to confirm that.
After all that work wiring it up I never even tried it out. I'm sure it would have got the job done though. It has a remote turn on built into it but no EQ control. It boosts the signal level output to 9.5 Volts per channel.
Looks like you ordered a Big 3 kit instead if an amp installation kit.
The amp kit includes a 17 foot power wire, blue remote wire, RCA cable, black ground wire, 20 foot speaker wire, and black wire loom.
