on my old head unit i only had one set of pre-amp outputs and i had to use y adaptors to connect to my 5 channel amplifier. on my new alpine deck it has three sets of pre-amp outputs(front, rear, and sub). I am getting ready to add the pxa-h100 imprint software to my alpine head unit. I was wondering if i should go ahead and run three rca's to each pre-amp out,(run one to the front speaker, rear speakers, and sub). The reason i was wondering if i should do this is because on the pxa-h100 imprint software when you go to install it to your alpine deck it has the same three pre-amp outputs(front, rear and sub) Overall my question is should i run the three rca's to each pre-amp output or would it be ok to leave the y adaptor hooked up the way it is and just plug it into the imprint software. Basically I want to know which way will give me the best overall sound in my truck, which way do you think is better run new rca's to all three pre-amp outputs or leave it how it is with the y adaptor? thank you very much for your time and please help!!!! thanks :) gumbeelee
