Hi all, I can't for the life of me figure out if there is a good solution to this problem and I don't have the time to get reading on electrical books.
I'm upgrading the bass in my vehicle, I don't have the budget to replace the entire system. In my research the factory amplifier is applying equalization and crossovers before sending power to all the drivers--thus, I want to avoid getting a high signal from the speakers if possible. That means trying to get a signal from the factory pre-amp before the amplifier. In this vehicle, it's a differential balanced connection.
I read somewhere that attempting a connection to that differential line in parallel to my subwoofer amplifier, similar to tapping into a speaker connection, causes 'double termination' and will induce a lot of noise. Their solution was to get their magical harness they designed, which they don't make anymore--nor did it do what I want, which is to connect two of the channels to both the factory amp and my subwoofer amp.
Is there a sensible way of making this connection happen? I'm okay with a minimal amount of noise--this is a car after all, I'm not intending for super high SQ until I replace everything down the road, but if it's mass hissing because of some loop going on then clearly it's not going to work. Thoughts? Thanks!
