Hey guys:

I've got a car with the option of installing 6-speakers, but of course there are only 4 output channels from the empeg/Rio Car so what is the best way to add more speakers into the mix withour getting buzzing, humming or degrading sound quality? I'm thinking of using RCA Y-splitter cables on the front left & right outputs into two separate amplifiers in the trunk so that each lead can power a dedicated speaker. Is this the way the pros would do it?
