Amp w/ separate inputs 4 front & rear: Can/should I use only 1 input 4 all full range

[cad_3326 10+ year member]

Title says it: I'm looking to buy 2 (4 ch.) amp and most 4 channel amps have separate inputs for the front and rear channels... But I only have 3 preamp outputs on my H.U. and so I'd like to not need a 2nd input to one of the amps...If I'm going to run all 4 channels of an amp off of the same frequency range (prior to the amp crossover) , can I use a single input without losing the ability to adjust the gain on the amp independently for each pair of outputs?

Thanks for all the help guys.

WHY????

If I'm reading it correctly, just get a set of RCA splitters to fill in for the extra channels. Splitting RCA's is perfectly fine.

Yeah, I thought I could do that but I've heard that there's a pretty substantial loss in SQ when you split like that... Is there an economical 3 pre-amp in- 4 way out active crossover, that way I could split them all equally and gain something in the process? I thought about the audiocontrol 6xs> Is that a good solution?

No sound quality loss using RCA splitters.
