Seeking LOC advice
I think that I will need an LOC because I presume that this Alpine amp doesn't have differential inputs. I checked out Amazon but don't know which one I should get in terms of brand, # of inputs (2 or 4), any other specs or features (i.e. adjustments)?
If it makes a difference, I will use the amp in 5-channel mode to power the four cabin speakers and one sub.
Any expertise is appreciated!

I would call the company who makes the amp and ask it will accept the signal from the Bose radio. I called JL Audio direct before I did mine. Then you wont need a LOC. Just splice the speaker wire with RCA cables. Not sure your gonna want to run the factorys off that amp. May wanna grab some decent 4 ohm speakers. I got a set of Polks that sound decent pretty cheap.
All the wire colors are here in this section.

It's an Alpine MRV-F450. It is a few years old but never used. I have some Polks that are going in as well and a JL sub. Only keeping the Bose HU.
I'll check to see if I can just splice into the existing wires and run RCA's to this amp. If I need an LOC, any suggestions?
This leads me to another question. Since I have a 5-ch amp, do I need three RCAs going into the amp? Or should I be good with just the front and rear RCAs? The amp has three RCA inputs (one for the sub). My old Alpine HU had three RCA outs (one dedicated for the sub), I guess I wont be able to control the sub with the Bose HU... is there a simple way to control it with this set up?

You will need 1 RCA cable to cut. It will make one cable for the front and one for the rear.
Some 5 channel amps have a switch so you can select the sub input to be one of the front or rear inputs. If your amp has such a switch, select the input to be the rear speakers so you can control the sub output.

and connect into the speaker wires coming out of the Bose amp.
You will need 2 RCA cables to cut. One for the front and one for the rear.
I'm still not clear which wires coming from the HU that I need to splice into. Is there a diagram? So the are called "low-level" wires?

Did you read the sticky thread about adding an amp to the Bose system? https://g35driver.com/forums/audio-v...g35-coupe.html
See if that will answer some of your questions. The wire colors are posted in several threads.
You are right about only needing one RCA cable and cutting it to make two cables (one for front and one for rear). I was thinking about something else. I fixed it in my post above.

Part of the DIY said "If you have ever cut open a standard RCA cable, you will notice that there are two conductors, one of which is often VERY tiny. Splicing such a tiny conductor to a speaker wire is very difficult and does not yield quality sound for your inputs (which the entire system is dependant upon!) Look for twisted RCA cables, or braided RCA cables. These use thicker gauge wiring for both conductors. INOXS makes cables that work well for this."
I called Alpine and they said that my amp accepts the signal -- I don't need an LOC. As a test, I cut open some old Stinger RCAs, in the middle where it becomes one cable, and saw four tiny wires running through it (white, black, red, yellow). Then I pulled each off the RCA connectors (both had a black AND white wire running to it.) What color wire connects to the + or - wire to the Bose HU? How do I know which color is L or R and + or -?
BTW, I have Navi. Does this add any complexity?
