Ok so here the awesome wiring diagram I used using Paint. I've been debating on whether to change the HU, but from reviews about discrepancies with the adapters available for MFSW I've decided to go with the Line Out Converter route for the sake of appearance and convenience.

Anyway, i'd like the opinion of audiophiles and some knowledge of doing this right. I'm a slight noob when it comes to wiring, but have done it before with an amp and sub, but never anything this extensive (for me anyway). Can someone give advice on what i'm doing is correct?
---------------------------------------------------------------
the specs:

2002 MCS with no Navi, no HK.

From what I understand about LOC's is that they take a speaker input and convert to a pre-amp output. Yes? No?

I want to take the speaker level output (PURPLE is the stock speaker wires) from the stock HU since it has no factory pre-amp outputs. I think I can cut the speaker wires from harness behind the headunit and attach HU Side of the speaker wires (shown in GREEN) to LOC. Yes? No?

I can then use RCA cable to attach LOC to four-channel amp (shown in BLUE). Yes/No?

I then put the amplified signal back into the speaker-side speaker wires of the (shown in ORANGE connecting to PURPLE) and therefore getting amplified sound to the speakers. Yes/No?

--------------------------------------------------------

Now for the remaining questions:

I plan on using an Audio Control LC6i Line Output Converter. Where does the remote out and remote in connect to (shown in CYAN). Does it need an Amp hook up kit with fuse and such just like the amp?

Same for the Amp. Where does the remote lead connect to?
I plan on using a 4-channel for the sake of simplicity, but would it be better to run two amps - one powering the front and one for the rear? I ask because the Polks that I am putting in can take more power and the amps that i've seen are usually 4x75-80 RMS, others higher but with $$$$$.

If what my diagram is somewhat correct, I am essentially wiring inline an LOC and Amp between the HU and speakers via the speaker wires?

------------------------------------------------------------------

I spent the better part of my afternoon drawing that because I really want to know. I've searched and searched, but got even more confused since many add a sub - something I may consider once I get more comfy, but for now powering four speakers with an amp seems plenty to me.

Also, I understand that product preference is a preference so i'm sure the components i choose may not be someone elses cup of tea, but please just let me know if I got the basics down so I don't blow up my car and not make this into a big "brand x is better than brand y so you should go with brand z" affair.
I got tired of listening to the Honda forums on whether my Polks were inferior to Infinitys ..
I'm on spring break next week so that's a week of ordering stuff through Amazon and installing it.

I do appreciate your time in helping me out with this, but I really want to keep the factory finish and steering wheel controls. I love my MINI, but my blown speakers are driving my ears insane.
