Both tweeters and sub woofers are designed to have a very specific frequency range they work in and adding a signal out side of that frequency range can damage them or your apmlifier (even the dinky 50W on in the head unit).
So to answer one of you many questions...
you can send the front output to the door 6.5" speakers first and put the crossover after them and the tweeters. This will put the full 20Hz to 26Khz audio frequency to the Polk 651s and limit the audio frequency to the tweeters to only the signal above 2500Hz (every thing below 2500Hz is too powerfull for the tweeters)
Your Head unit also sends a signal out to the rear channel
So you could use the rear channel for the door 651s and send the front channel to the tweeters through the crossover Boss provided
I sort of recommend this method because in my, car the tweeters over power the factory door speakers and cause the sound stage to sound like it is just behind the rev and clock pods....
If you set it up for the "fronts" to be tweeters and "rears" to be the doors then you can use the fader control top shift the sound stage a bit
When I re do mine in the next few weeks I am adding 4" mids in the rear hatch sides and home brew short depth 8' sub woofer and amp where the factory crap is under the driver seat
I will replace the factory speakers with Boss 6.5s and silk domed tweeters with supplied crossovers
I am still fussing with what head unit I want ...real hard to find all the features I want in one box
RDS
HD
Sirius
USB
Blue tooth
The RDS seems to be a rare item in most Head units
Can you add more information as to the wiring? In the "premium" sound package it appears that the tweeters and powered subwoofer are connected in parallel to the main speaker outputs. Do you have any more specific information?
A lot depends on if you are keeping the radio 10 or adding a headunit
I intend run all new speaker and power wires and leave the factory speaker wiring and connectors in place un hacked...I will store the radio 10 and sub woofer so I can put it all back to factory come sale or trade in time
It seems to me, from the few diagrams I have seen, that the radio 10 has the tweeter crossover designed in... they send tweeter left and right as seperate circuits...they send door left and right as seperat circuit and steal the powered sub woofer signal from one ( or both ) of the door speaker circuits I assume in the under seat powered 30 amp assy has a low pass filter to block the mid and high frequrncy signals
8 foot sub.... damn I need to pay attention to ' or " usage...but for the record... of the many concerts I went to in my youth, I am convinced several of then had 12' speakers
Largest speakers I ever had were a set of Sansui with 15" woofers and they would move a full wall locker across my barracks room.... grin
An 8" sub will work, some people mount it under the dash, I am trying to design a JL 13" shallow sub in a downfiring position underneath the seat. The woofer is only 2.5" thick... So yes you can mount an 8" sub, kicker,sony,kenwood, and pioneer all make one.

Fred, thanks for the info. Good idea keeping the radio 10. I was going to sell it. I hooked up my Kenwood. There are crossover settings that I can adjust to make sure the tweeters get the right freq. I'm going to keep the stock speakers for now.
