You can take your original pair of RCA's from your head unit, plug it into the 6XS and then have front (high/mid), rear, and sub outs with adjustable pre-amp voltage... checkout
www.audiocontrol.com They have other equipment that may also meet your need. I currently own an 6XS and enjoy it very much.
It's a little late, and my electrical theory part of my brain has already fallen asleep. But how do you figure it will cut the power in half? Depending on his preamp levels that he's currently got, I'm going to guess that it's between 2v-4v. Splitting the signal does NOT cut voltage in half. The only way it is possible to cause a voltage drop if the amperage draw on whatever preamp decice he is using, is becomes higher than what it can produce. But we're talking miliamps of draw here. I don't see splitting the signal between two amplifiers putting a significant strain on the preamp, and "sucking it dry". Especially if he's using line drivers.
And so what if he drops his preamp power half a volt (if it even did in fact happen)? He should still have ample power to get a good clean signal to his amplifiers.
Maybe I'm wrong, but I've NEVER had problems splitting an input signal.
At any rate, spending $200 on a crossover to split a signal to two seperate amps is a bit silly. If he actually needs that, then fine. But in the case of just splitting a signal to add more subs, esentially all he would be paying for would be the line-driver aspect of it, and those can be had for WELL under $50...
