Need urgent help installing new audio system

[Stefan Hayes]

So, at the last minute I realized I made an awful mistake with my girlfriend's christmas audio surprise. I purchased her a new head unit that only has 4 preamp RCA's instead of 6 preamp RCA's (in the picture it looks to be 6 channel, but it's actually just 4 :/ ). Below I have listed the specs of everything in her cars audio build. Need some help quick on what to do!

Wire: 4 Ga Power and Ground, 14 Ga Speaker Wire, All Sky High Car Audio brand

RCA: Stinger 6-channel RCA

Speakers: http://www.sonicelectronix.com/item_5474_Soundstream-SST5.7.html

Sub: Digital Designs Redline 400 /OR/ 500 series 15" subwoofer, 150-400w RMS, 1200w peak (http://www.ddaudio.com/products/mobile-audio/redline/500-series) (I can't find a 15" model of this anywhere but the sub is def a 15" and it says it on the back that it's indeed Redline)

Amp: http://www.sonicelectronix.com/item_79512_Soundstream-TA5.1250.html

Head Unit: http://www.crutchfield.com/S-rJ2eMuQEvgm/p_158XAV68BT/Sony-XAV-68BT.html

Keep in mind, no, this is not supposed to be the greatest audio setup out there. She likes her music but also wants a decent system, I like mine heavy and loud with sound quality and sub pounding. Two different tastes. Is there anyway I can make this work? Really appreciate any help, still a bit of a noob with this stuff.

Besides the subs, how many speakers are you hooking up to the amp?

OP, it's feasible, you just have to read instruction manuals and in the worst case you may need some RCA Y cable to split the signal.

I'm hooking up 4 of those 5.7's, and only running the one 15" DD. My father mentioned I could maybe try an RCA splitter, but I can't seem to find them on Amazon. Trying to get them here quickly with their guaranteed 2-day shipping since it's almost Christmas.

one female to two male rca splitter is what your after, two of them, then you'll end up with 3 pairs of rca's going to your amps

Here. Suprising enough, I got that by typing this into google: "RCA Y adapter Amazon"

OP, those splitters may not even be necessary. Read the instruction manual for the amp and see what the 2/4/5 channel switch does

if you can't figure it out with rockford's advice, you could probably get that y adapter from best buy/radio shack......just a thought.

Sorry, I'm still a bit new to this. I've hooked up my own amps before but this will be my first full fledged project from start to finish. I just don't want to mess it up, you know? Also, would this work better? (http://www.amazon.com/Rockford-Fosgate-Twisted-Adapter-Female/dp/B006RAT7GA/ref=sr_1_3?ie=UTF8&qid=1418880626&sr=8-3&keywords=1+male+to+2+female+rca) I have a 6-channel Stinger RCA cable. Am I wrong with this adapter, or is it what I need?

I'll check out the manual for the amp tomorrow, maybe it has a magic switch like you say? That'd be fantastic

Yeah unless you live in BFE, theres probably a dozen local places with a resonable selection. Avoid em if you can there, and read up on the amp.
