Help - Need Clarification
Okay, so. Here is the list of what I have:
Two 10'' Alpine Type R subs enclosed already.
A 4 channel amp.
A 4 channel headunit (SONY CDX-GT550UI).
All amp wiring necessary.
Unfortunately - I have BOSE Premium Sound.
I want to clarify, because Crutchfield is saying I need to get a 6 channel headunit, so I can use their harness (this one) that I connect to 2 of the pre-amp outputs to power the speakers, and the final sub pre-amp output to power the new amp/subs.
I don't necessarily want to buy a new headunit when I just bought this 4 channel one and learned the hard way that BOSE sucks with adding a sub.
Can I use...say this harness (http://www.pac-audio.com/productDeta...&CategoryID=26) instead...to power the speakers using these line outs and power the sub/new amp using the RCA pre-amp?
I would appreciate any help/direction. Thanks.

To keep it the simplist... and cheapest....
Keep bose head unit and speakers. You can get a Line converter to splice into your speakers to convert speaker level to RCA level signals to input your amp to power your speakers.

Some amps have built in speaker level inputs that i would recommend before using a converer.

If you want to do it right, Get a good headunit, run RCAs to both a monoblock amp for a sub and a 4 channel amp to your rewired components.

There are a bazillion different ways to do this, but if I was doing it myself, I'd try one of the following:
Option 1 - Buy an additional dedicated sub amp
-------------------------------------------------------
Use two RCA Y adapters to split the rear preamp so that you have 6 preamps & can run an amp connection to each speaker.
Option 2 - Use combination
--------------------------------------------
Use front preamps to AMP, then to front speakers. Use radio's line level outputs to rear speakers. Use radio's rear preamps to AMP, then to subs.
Option 3 - Combine Speakers
----------------------------------
Use the front preamps for the speakers and the rear preamps for the subs.
Driver Front & Driver Rear (in parallel) ---> AMP Left 1
Passenger Front & Passenger Rear (in parallel) ---> AMP Right 1
Sub 1 ---> AMP Left 2
Sub 2 ---> AMP Right 2

I appreciate your responses guys and will take them into consideration; however, I am still curious about whether or not the setup I described would work..? I want to know if I use the ROEM-NIS2 adapter to run my speakers. And use my 4-channel aftermarket amp (that I have lying around) to run my sub. I really don't want to spend any more money than what I already have. I'm not trying to use my 4-channel amp to power my speakers, that's the point of me getting the ROEM-NIS2 harness - so I can power the speakers using the existing BOSE amp.
tl;dr - Can I use BOSE amp to power speakers with the ROEM-NIS2 harness & power sub with my other amp?
^ All that is using the aftermarket headunit, of course, not stock BOSE unit.

Now, can you bridge your 4 channel amp? If so I would do that and run your two subs in stereo off the bridged channels of the amp. Keep in mind this will only work is the ohm load is compatible. I need more info on your speakers and amp to see if this best route.
Best bet (as other suggested) skip the Bose amp, use your 4 channel amp to drive the factory speakers and add a dedicated sub amp to power your subs. Option #2 from SparkleCityHop is one I recommend to most people since your rear speakers don't need that much power. Use the 4 channel amp to drive the fronts and subs if you can bridge the 2nd (or rear) channel.
