ok i want 3 channels with 2RCA preouts on my HU. I realize i wont be able to fade. anyways do i use the Y connectors like situation A or B?

Situation A:
Two connectors...with one female end and two male ends. Each male end of each connector goes into the female of the amp for both front and rear. Then RCAs ran to deck.

Situation B: Two connectors...with one male and two female. Each male is hooked into the R/L of my Front or Rear preout of my deck and then RCAs ran to amp.

if its neither of these, let me know, i just need to know how to do this.

also my kicker kx 1200 has a preamp output, but i tried to use it and i dunno, i think it might be lowpass only. help me out please.

three channels or three pair of RCA connectors?

The best way to do this is via an electronic crossover like the Coustic XM-3 or Audiocontrol 3XS

i need three channels (front/rear and sub out) and my HU only has rear and sub out.

are you using a 4ch amp? some may have a switch or something that says front only, or rear and front. meaning, you switch it to front only and it takes in only 1 pair of RCA. i dont like daisychaining amps cause you can get some mad delay.

if your hu only has rear and sub out, then that is the signal that will be sent. but like kiki said, a 3xs you will take one of those rca's and the 3xs turns it into 3 pre amp outs. you will adjust the the crossover settings on the 3xs, but you will still be using the rear pre amp out from the deck, and that is the signal that the 3xs will have to work with.

actually, you'd probably end up getting a 2xs. if you have a pre amp out for the sub, then it can go straight to the sub amp. but the rear channel will have to be split. you can do this with just a few simple y-adapters if you're on a budget, but the more appropriate and for better sound, you'd better get a audiocontrol 2xs.

btw, is this for 3 amps or what?

im sorry, by 2xs and 3xs are you referring to a xover?

this is for two amps. a JL 300/4 (used for fronts and rears) and then a kicker kx 1200 for the sub. im thinking im just gonna take the rears out now and use the open hole as a sort of port for the sub...

and how much would that acoustic crossover cost..how do you hook them up etc?
