So I'm at a crossroad right now. I can either use my current headunit that have 2 pairs of 2v preamp outputs or I can upgrade and get a new headunit with 3 pairs of 4v preamp outputs. Currently I'm using a Y splitter to connect my speakers to my 4 channel amp and the other pair of RCAs is going to my sub amp. Will switching to the 3 pars of 4v preamps give me any significant benefits?
