its all up to you and what you want man. you only have a pair of type r's to keep up with so i would say your going way overkill. to me, when i want loud i only care about the subs. when i want loud SQ i turn the subs down to a balanced level. but then again the MECA guys have brainwashed me to think like that now.
remember with all these speakers, they all need crossovers. going active would be the easier and probably cheapest way. not to mention it's the best way to go lol. your mids will need to be bandpassed, your midbass will need to be bandpassed as well but that can be done with a lowpass crossover and setting the HPF on the hu, or the amp. then the high pass for tweeters.
im curious, how much do you think your idea will cost you? speakers, crossovers, and amps? what kind of stuff are you looking at?
