Help a newb with amp questions

Im looking to either replace my stock amp or add an additional amp to give my interior speakers a little more sound. Im not that skilled so the im looking for the easier route.

I have a 04 acura TL. I replaced the front doors, tweeters, center channel and rear deck with infinity kappa speakers (all 2 ohm)a while back and kept the stock amp to power them. They sounded better but lacked any serious sound. I also have one 10" type-r in sealed box. For that i added a loc to the stock sub wiring.

Im thinking that replacing the stock amp and rewiring all the speakers might be too much work for me. Instead, I was wondering if i could just add another 4 channel amp to power the interiors (the tweeters and front door speakers share the same line)

Can I add something like ALPINE MRP-F300, take the speaker wires AFTER the oem amp for the doors/tweeters and rears, run them into my new 4 channel amp then back to the speakers and be done with it? I say after the oem amp b/c Ive read that the stock head units signal is too weak.

Does it work like that?

The problem with that idea is that the factory amp controls the frequency distribution to all the speakers. You'll never get any midbass to the front speakers cuz the amp filters it out. The only way to get full control of the system is yank the factory amp.
