    Do I need a L and R RCA signal going to amp for 2 channels I'm bridging?

    Title pretty much says it all. Will be taking sub signal from the factory headunit and there is only one positive and one negative wire which will result in one output. The signal is for a sub that I am running off the rear channels (bridged) off a 4 channel amp.

    Thanks in advance..

    You will only have one working channel if you are using 2 bridged channels total. Which means only one channel would be playing.. You can always use a Y splitter though

    you wont have as much output even with a y splitter since youre using a 4 channel

    Signal is first going thru a line driver before the amp, does that make a difference? What would you recommend I do? There is a setting on the amp to use the inputs for channels 1 and 2 but the reason I want to use the sub signal is so I don't lose the functionality of the sub volume control on the head unit.

    Split the output of the line driver into both input channels. You need both inputs.
