check your specs. Unless i'm mistaken, the center and subs channel jack are the same. You'll need a high and lowpass crossover, i believe. If you wan't be deterred, have fun with that. Yeah, i'm doing my stuff form barters and preexisting. I STILL have a good half grand to spend since i need a screen. If you ever get tired of the screen, let me know. I'll have friends who'll want it when i finish my setup ;-).
Infinitys are what i'm using (going to be using when i install). Circuit City is having a sale right now for their subs if you're interested. 2 for 1. 100 for 10" 110 for 12". Audio shops are stupid when it comes to this. We're out of their league. Just remember to have a 4 channel amp for your speakers. Personally, i have an oldschool Rockford Fosgate 4040DSM. Now only do i have front and rear in seperate channels, i can dasiychain my amps. You wont' need that with 5.1. Actually, you may want TWO 4 channel amps, alteast one with buitl in crossovers. Have your left and right signals split between the front and rear inputs and use the buitl in crossovers to set the front (center) to high pass and the rears (subs) to low pass. I'm just wondering how you'll direct the power... just read what i said about KISS and interface and distractions on yrou last thread. If you want to view MY progress, here it is
