System Advice...I am new

[wsudu]

Ok...So I get this Acura Legend and I want a kick ass stereo for it. I get a z828 excelon head unit for it and 2 kappa 4" for up front with 2 kappa 6x9"s for the back. I just ordered 2 Kappa 12.1 perfects SVC's and (just like they suggested) but it in a sealed 1cf box.....I eventually want a JBL 1200.1 amp for them cause everyone says thats a great amp for them, but not yet. Heres the question.......I have a left over Kenwood KAC -728s amp. It says its 600watts and it stereo. So if I bridge it, how many watts per sub...Is this ok....I read a 2 page argument about clipping and underpowering subs, so I want to be ok for the time being....Do I fill the box with Poly Fill?..if so why....Give me some tips.....Will I need a cap later with that JBL????

Last can I take that kenwood amp and run the 4's and 6x9's later? How..

YOU CAN SEE I NEED YOUR HELP....THANKS IN ADVANCE

well the specs on the newer version of the kac728s (new=ksc729s) say that it is rated at 300w RMS x 1 at 2ohms. which means about 150 watts per sub if wired in parallel. you will be fine using this setup until you get the better amp. and then you can use the kac728s to power the FRONT speakers and NOT the back. the reason you would use poly fill is if your box is smaller than spec according to the sub manufacturer.
