ok can i take a rca y splitter and split both the left and right signals of the headunits rca outs and send them to a 4 chan amplifier.
from there i am confused a lil on the amplifier im looking to buy the crossovers are for front and rear but allow for Hi low and Flat.
It looks like it has the filter of 32-320hz, if i split the signal with y splitters could i set the front channels for the woofers with a highpass filter set to like the 320hz and then the rear channels for the tweeters set with a low pass at 320hz?
