I was wondering what the thoughts and advice are on:

- Alpine PXE-H660 System Integration Audio Processor

-Alpine PDX-5 5 channel amp
http://www.alpine-usa.com/product/view/pdx-5

-8" subwoofer?? im lost!!! please help!! i dont want SPL i want SQ. dont need 130db but i would like something decent. price range $200-600 for sub
i wouldnt mind just changing out the factory sub and put in a new aftermarket one in the same hole. would it work??

i have an 08 acura mdx with NAVI. and will be putting in audison or hertz speakers in the car. but not sure on amp (only getting 1) and audio processor(easy setup). i have factory navigation and i want to keep ALL oem items and functions. I want my system to look completely factory. thanks
