ok super noob here, never did this before and i needed help from the gods of audio. ???????? of the day is..... does your preamp volt drop if you split the signal path?i have a pioneer head unit with a 4volt preout im trying to fig out which way to go on this. im running 2 alpine mrp-450s to my subs. is the best way to do this should i split the signal and use 2 rcas? or run one then split it at the amp end? or run one then use the pass through rca on the amp for the signal to signal from my other amp? sorry to sound like a dumb ass. but ive heard to many know it alls today that didnt even know what the hell signal noise ratio was. thanx for any help dam im tired this above was for the sub preout only.

No. To an extent. But that extent DOESN'T involve only two amplifiers. You can run two RCA's (my third choice), split it at the amp end (my second choice - first if the next option does not apply), or use the pass-through (my first choice, if there is no additional signal processing inside the first amplifier, including crossover functions).
Voltage doesn't get split in a parallel circuit - current does. If you wire two amplifiers to one battery, the voltage remains the same, right? RCA signal voltage is the same thing - voltage.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

omg some one changed me title lol, ok so i took my head out of my ass and act looked at the correct book for my amps lol these dont have the pass throughs my 5 channel alpines do. so i will run the 1 rca and split it at the amps via some high end patch cables. i do have another ? didnt want to start another thread. due to the happy nature of ground issues with pioneer head units. ive grounded it to the stock gm ground post if that dsnt work to the batt. ?????? is i have some monster xln noise killers would i put them at the head unit or the amps? due to the ext cramped space on caddys there is very little space?. thanx for the info on my prev ?.
